Smartphones have become an inseparable part of modern life, revolutionizing communication, work, and entertainment. However, excessive smartphone use (ESU) has been linked to various negative consequences, including addiction-like behaviors, impaired mental health, and diminished attention spans. Recent studies suggest that smartphone-related cues can trigger neural responses similar to those seen in substance addiction, reinforcing compulsive usage patterns. Understanding the effects of smartphone restriction on cue-related neural activity can provide valuable insights into developing interventions for individuals struggling with ESU.
The Role of Cue Reactivity in Smartphone Use
Cue reactivity (CR) refers to the brain’s response to stimuli associated with a habitual or addictive behavior. In the case of smartphone use, cues may include notification sounds, phone screens lighting up, or simply seeing a smartphone in one’s environment. These cues can activate reward-related brain regions, reinforcing the compulsive urge to check the device.
Research has shown that individuals with excessive smartphone use exhibit heightened neural responses to smartphone-related cues, similar to those observed in substance addiction. This heightened sensitivity may contribute to difficulty in controlling smartphone usage, leading to a cycle of compulsive checking and craving.
Investigating Neural Activity Changes Through Smartphone Restriction
To better understand how short-term smartphone restriction influences brain activity, researchers conducted a study using functional MRI (fMRI) to measure changes in cue-related neural responses over 72 hours of smartphone abstinence. The study involved 25 young adults who were regular smartphone users.

Study Design and Methods
- Participants were instructed to refrain from using their smartphones for 72 hours.
- A cue-reactivity task was designed, where participants were exposed to images of smartphones (both active and inactive) as well as neutral objects.
- Functional MRI scans were conducted before and after the restriction period to analyze changes in brain activity.
- Psychometric assessments were used to measure craving, self-control, and emotional responses associated with smartphone use.
Key Findings: How the Brain Adapts to Smartphone Restriction
1. Reduced Activation in the Reward System
One of the most striking findings was a significant reduction in activity in the nucleus accumbens and anterior cingulate cortex after 72 hours of smartphone restriction. These brain regions are heavily involved in reward processing and habit formation.
- The nucleus accumbens is associated with motivation and reinforcement learning. High activation in this area suggests strong craving and compulsive behavior.
- The anterior cingulate cortex plays a role in decision-making and impulse control. Reduced activity here indicates that participants may have experienced less compulsion to check their smartphones.
These findings suggest that even a short break from smartphone use can lead to neuroplasticity, allowing the brain to become less reactive to smartphone-related cues.
2. Alterations in Dopamine and Serotonin-Linked Activity
Further analysis using neurotransmitter probability maps revealed that activity changes in the reward system were closely linked to dopamine and serotonin receptor probabilities.
- Dopamine is a key neurotransmitter in reward-seeking behavior and addiction.
- Serotonin is involved in mood regulation and impulse control.
The findings suggest that smartphone restriction may influence neurochemical processes that drive compulsive behaviors. This could explain why some people feel withdrawal-like symptoms, including restlessness and anxiety, when they suddenly stop using their phones.
3. Increased Engagement of the Parietal Cortex
Another notable result was the increased activity in the parietal cortex, a region associated with attentional control and sensory processing.
- This suggests that participants became more aware of their environment and less preoccupied with smartphone-related distractions.
- Heightened parietal cortex activity was correlated with reduced craving scores, indicating improved cognitive control over impulsive smartphone use.
This supports the idea that limiting smartphone use can enhance focus and attentional regulation, reducing dependency on digital devices.
4. Reduced Compulsive Checking Behavior
Behavioral assessments showed that participants experienced a significant decrease in the urge to check their smartphones over time. This aligns with the observed neural changes in reward sensitivity and impulse control.
Participants also reported improvements in:
- Sleep quality: Reduced exposure to blue light and nighttime scrolling led to better sleep patterns.
- Social interactions: Without constant phone distractions, participants engaged more with people around them.
- Mental well-being: Several individuals noted feeling less anxious and more present in their daily activities.
Implications for Smartphone Addiction and Digital Detox Strategies
The findings of this study have significant implications for individuals struggling with excessive smartphone use. While a complete break from smartphones may not be feasible for everyone, implementing digital detox strategies can help manage usage and mitigate negative effects.
1. Scheduled Smartphone Breaks
- Taking regular breaks from smartphone use, even for a few hours a day, can help reset neural responses to digital cues.
- Setting specific times for checking messages rather than responding to every notification can reduce compulsive checking.
2. Mindful Technology Use
- Practicing conscious smartphone use by turning off unnecessary notifications and using grayscale mode can help decrease reliance on digital stimuli.
- Engaging in non-digital hobbies, such as reading, exercise, or meditation, can strengthen attention control and reduce smartphone dependency.
3. Sleep Hygiene and Nighttime Restrictions
- Avoiding smartphone use one hour before bed can improve sleep quality by preventing blue light exposure.
- Using do not disturb or airplane mode at night can minimize the temptation to check notifications.
4. Awareness Campaigns and Education
- Schools, workplaces, and mental health professionals can promote awareness of the impact of excessive smartphone use on brain function.
- Implementing digital wellness programs can encourage balanced technology use.

Conclusion: How Smartphone Restriction Reshapes the Brain
The study provides compelling evidence that even a short period of smartphone restriction can lead to measurable changes in brain activity. The observed reductions in reward-related neural responses, coupled with increased attentional control, suggest that limiting smartphone use can promote cognitive flexibility, impulse control, and overall mental well-being.
As smartphone addiction continues to be a growing concern, understanding the neurological basis of cue-reactivity and digital dependency is crucial. These findings highlight the importance of incorporating healthy technology habits to ensure that smartphones remain tools for convenience rather than sources of compulsive behavior.
By making small adjustments in smartphone usage, individuals can foster better focus, improved mental clarity, and greater overall life satisfaction. So, why not start with a 72-hour break and see how your brain adapts?
Matthew Perry has reportedly died. The “Friends” actor was 54
Actor Matthew Perry, famously known for the role of Chandler Bing in the iconic show Friends, was found dead Saturday in a hot tub at his Los Angeles home, law enforcement has reported.
Spokesperson of the LA Fire Department reported that first responders arrived at Perry’s home at about 4 p.m. regarding a “water emergency” of an unknown type, but did not name the actor. Sadly, upon arrival, they discovered Perry’s unresponsive body. According to them, there were no drugs of any type at the scene. At the time being, no foul play is suspected.
A representative of the actor hasn’t issued any comments regarding the tragic incident.
The investigation over Perry’s passing is still ongoing and the cause of death remains unknown. It will be determined by the Los Angeles County coroner’s office at a later date.
“We are devastated by the passing of our dear friend Matthew Perry,” Warner Bros. Television Group, which produced “Friends,” said in a statement to The Times. “Matthew was an incredibly gifted actor and an indelible part of the Warner Bros. Television Group family. The impact of his comedic genius was felt around the world, and his legacy will live on in the hearts of so many. This is a heartbreaking day, and we send our love to his family, his loved ones, and all of his devoted fans.”
“We are incredibly saddened by the too soon passing of Matthew Perry,” NBC, which aired the series for all 10 seasons, said in its own statement to The Times. “He brought so much joy to hundreds of millions of people around the world with his pitch perfect comedic timing and wry wit. His legacy will live on through countless generations.”
Saturday evening yellow-and-black LAPD crime scene tape blocked off the entrance to Blue Sail Drive, a tony street just off the Pacific Coast Highway at the crest of a hill with sweeping views of the Pacific Ocean.
Shortly after 7 p.m., as multiple helicopters whirred overhead, Perry’s mother, Suzanne, and her husband, broadcaster Keith Morrison, joined the journalists and LAPD officers on the scene. Morrison declined to comment. An LAPD officer at the scene said he had no information and that he did not know when any would be forthcoming.
Peter, a neighbor of Perry’s on Bluesail Drive who declined to give his last name Saturday evening, said he only spoke to the actor once, for five minutes, and that he was “very pleasant” and a “nice guy.”
“It’s shocking,” Peter said as he waited for the LAPD, who had barred journalists from passing the police tape, to approve him for entry. “He’s been redoing this house forever and he seemed fine. It’s very sad.”
Leo, another neighbor who declined to give his full name, said he was home when an ambulance arrived at Perry’s house Saturday afternoon. He declined to say whether paramedics tried to revive Perry or if a body was removed from the premises.
“I was shocked,” he said. “It was very disturbing and sad after all these years.”
Perry was one of his favorite actors, Leo said, and the funniest member of the “Friends” cast.
“I encountered him once and he was very, very friendly. More so than I thought,” Leo said. “It’s definitely a tragedy, especially at such a young age,” he added. “I was very heartbroken to see what happened.”

Perry, the son of actor John Bennett Perry and Suzanne Marie Langford, onetime press secretary of Canadian Prime Minister Pierre Trudeau, was born in 1969 and grew up between Montreal and Los Angeles after his parents separated when Perry was 1.
He got his start as a child actor, landing guest spots on “Charles in Charge” and “Beverly Hills 90210” and playing opposite River Phoenix in the film “A Night in the Life of Jimmy Reardon” in the 1980s and early 1990s.
But his big break came when he was cast in “Friends” — originally titled “Friends Like Us” — a sitcom about six single New Yorkers navigating adulthood that premiered on NBC in 1994.
The series soon became a juggernaut, the anchor of the network’s vaunted Thursday-night “Must-See TV” lineup, and turned Perry and his castmates Jennifer Aniston, Courteney Cox, Lisa Kudrow, Matt LeBlanc and David Schwimmer into mega-stars almost overnight. At its high-water mark — for a 1996 Super Bowl episode and the 2004 series finale — the series could notch more than 50 million live viewers; by its end, cast members were earning more than $1 million an episode.
As Chandler Bing, the handsome, wisecracking roommate of LeBlanc’s Joey Tribbiani and, later, love interest of Cox’s fastidious Monica Geller, Perry distinguished himself in a crackling ensemble cast. With his dry delivery he created a catchphrase with a mere turn of inflection, based on banter he’d shared with childhood friends: Could he be any more Chandler?
Soon, he was attached to major stars like Julia Roberts and appearing in prominent films such as 1997 rom-com “Fools Rush In,” opposite Salma Hayek, and 2000 ensemble mob comedy “The Whole Nine Yards” with Bruce Willis.
There was a dark side to the life of one of television’s most beloved funnymen, however. In his 2022 memoir, “Friends, Lovers, and the Big Terrible Thing,” Perry recounted his lifelong struggle with addiction to alcohol and opioids. He wrote that he had his first drink at 14, but didn’t recognize the signs of alcoholism until 21. Since then, he estimated, he’d spent more than $7 million on efforts to get sober, including multiple stints in rehab. His substance abuse also led to a number of serious health issues, including a five-month hospitalization in 2018 following a colon rupture that left him, he wrote, with a 2% chance to live through the night.
And it was fueled, he acknowledged during a “Friends” reunion special in 2021, by the pressure to land the joke in front of a live studio audience night after night.

“Nobody wanted to be famous more than me,” Perry told The Times in April, discussing “Friends, Lovers, and the Big Terrible Thing” at the Festival of Books. “I was convinced it was the answer. I was 25, it was the second year of ‘Friends,’ and eight months into it, I realized the American dream is not making me happy, not filling the holes in my life. I couldn’t get enough attention. … Fame does not do what you think it’s going to do. It was all a trick.”
Perry was remembered on Saturday by friends and collaborators such as Selma Blair, Paget Brewster, Morgan Fairchild and Mira Sorvino as a singular comic talent and kind soul.
Perry’s “Friends” co-star Maggie Wheeler, who played his on-again, off-again girlfriend Janice on the hit show, shared a sweet tribute on Instagram.
“What a loss. The world will miss you Mathew Perry,” she wrote. “The joy you brought to so many in your too short lifetime will live on. I feel so very blessed by every creative moment we shared.”
He was also memorialized by Canadian Prime Minister Justin Trudeau, Pierre’s son and one of Perry’s childhood friends.
“Matthew Perry’s passing is shocking and saddening,” Trudeau wrote on X. “I’ll never forget the schoolyard games we used to play, and I know people around the world are never going to forget the joy he brought them. Thanks for all the laughs, Matthew. You were loved — and you will be missed.”
Though Perry estimated he had relapsed “60 or 70 times” since first getting sober in 2001, he maintained a steady presence on American television, playing key parts in backstage dramedy “Studio 60 on the Sunset Strip” and therapy sitcom “Go On,” and making a steady stream of guest appearances on acclaimed shows such as “The West Wing” and “The Good Wife.”
Since his near-death experience in 2018, Perry had found solace in friends, frequent games of pickleball and, especially, writing. Though producing “Friends, Lovers, and the Big Terrible Thing” had forced him to relive his darkest moments, it also connected him to “all the sufferers out there”: “I had a story to tell, a story that could really help people,” he wrote. “And helping others had become the answer for me.”
Indeed, for all his success as an actor and, more recently, as a bestselling memoirist, Perry told The Times in April that his work was not the center of what he hoped would be his legacy.
Pressed to name how he’d like to be remembered, he said: “As a guy who lived life, loved well, lived well and helped people. That running into me was a good thing, and not something bad.”
