Smartphone Use Changing our Brain – Researchers
Typing text messages, scrolling web pages, and checking your email on your smartphone could be changing the way your thumbs and brain interacts. That’s according to researchers from the University of Zurich, ETH Zurich, and University of Fribourg.
Dr Arko Ghosh, of the University of Zurich and ETH Zurich, led the research which involved using electroencephalography (EEG) to measure the cortical brain activity in 37 right-handed people, 26 of whom were touchscreen Smartphone users and 11 users of old-fashioned cellphones.
A total of 62 electrodes were placed on an EEG cap worn by subjects to record how the brain processed touch from their thumb, forefinger and middle finger.
Brain activity was then compared with the individual commands recorded by each individuals’ phone logs.
“We measured people’s brain activity using a bunch of electrodes on the scalp and what these maps indicate is essentially how much of the variance between people we could explain by just looking at the phone logs, so how much brain activity can be explained by looking at people’s history of use on the phones alone,” said Ghosh.
Pointing at brain scans on his computer he added: “For instance these red spots here indicate when you measure the signals of these electrodes a lot of the differences between one person and the next can be explained simply by how much phone they were using in the previous ten days.”
Electrical activity in the brains of smartphone users was shown to be enhanced when all three fingertips were touched.
According to research student Magali Chytiris, activity in the cortex of the brain associated with the thumb and index fingertips was directly proportional to the intensity of phone use, as quantified by built-in battery logs.
“This activity is related to the amount of use from the past days of phone use,” said Chytiris. “So we used the logs, the battery logs, from the phone and we found that if the EEG recording was just after the peak of high intensive use then the brain activity was higher.”
Ghosh says the results suggest that repetitive movements over the touchscreen surface reshape sensory processing from the hand, with daily updates in the brain’s representation of the fingertips. He believes that cortical sensory processing in the contemporary brain is continuously shaped by personal digital technology.
“Most superficially what we found was that smartphone users have a brain that processes touch differently than people who don’t use smartscreen touch phones,” said Ghosh.
“However, if you dig a bit deeper into the data what you essentially see is that the most recent usage that people accumulated on their smartphones that reflected on the way that brains processed information from their fingertips. So essentially these day-to-day fluctuations that we encounter through our daily lives they imprint on the brain on the way that it processes information from your hands.”
Ghosh says that smartphone use is an ideal way to explore the everyday plasticity of the human brain. “It gives us a very good excuse to go back and look into the phone logs in greater detail to understand how our digital histories could be used to understand brain function and develop real world solutions by studying the real world example of brain plasticity,” he said.
MTN Nigeria has marked 25 years of commercial operations, with Karl Toriola, chief executive officer, saying the company began operating in the country at a time when telecommunications access was severely limited.
Toriola said that a quarter of a century ago, making a phone call was a privilege few Nigerians could afford.
People queued at public telephone booths and centres, travelled long distances to deliver messages, and sometimes waited weeks for letters to arrive, he said, noting that a mobile phone was then beyond the reach of most.
Today, the company connects more than 90 million people across Nigeria, a figure MTN says reflects its role in building the infrastructure behind the country’s shift to a data-driven economy.
MTN entered Nigeria in 2001 following the GSM liberalisation carried out by the Nigerian Communications Commission (NCC), at a time when mobile telephony was still a luxury reserved for a privileged few.
Toriola said the milestone was about more than subscriber numbers.
Businesses have been built, families have stayed connected across distances, students have gained access to knowledge, and creators have found audiences beyond Nigeria’s borders, he said, crediting the wider telecommunications ecosystem for enabling entire new industries to emerge.
The company also pointed to its role beyond direct connectivity.
MTN has helped build a wider value chain of SIM registration agents, tower contractors, retail distributors, fintech partners and digital developers that now supports millions of livelihoods in Nigeria.
Toriola thanked MTN Nigeria’s customers, saying their trust had allowed the company to expand its community investments through the MTN Foundation, which has supported health, education, youth development and economic empowerment programmes.
Looking ahead, the CEO acknowledged that significant connectivity gaps remain, with millions of Nigerians still needing access to reliable, affordable and inclusive digital services.
He said greater digital inclusion would be a central priority for the company’s next chapter, adding that the anniversary marks both a celebration of the past 25 years and a renewed push to expand digital access for the country’s young and growing population.
“We’ve come a long way. And we are only getting started,” Toriola said.
The anniversary comes as MTN Nigeria continues to navigate rising operating costs tied to Nigeria’s unreliable power supply.
Where the national grid is unreliable, the company and its infrastructure partners have had to rely on diesel generators, batteries, solar systems and other backup power solutions, making network operating costs highly sensitive to fluctuations in diesel prices.
Telecommunications subscribers under the umbrella of the National Association of Telecoms Subscribers (NATCOMS), has handed telecommunications operators in the country September deadline to improve network quality or face legal action.
Deolu Ogunbanjo, president, NATCOMS, said that subscribers have endured deteriorating network services despite repeated interventions, warnings, and sanctions by the Nigerian Communications Commission (NCC).
As reported by BusinessDay, Ogunbanjo, noted that if the situation fails to improve through regulatory intervention, NATCOMS will seek justice through the courts by the end of the third quarter.
The ultimatum comes as rising data consumption, subscriber migration, and growing demand for mobile services place severe pressure on network infrastructure across parts of the country.
The NCC stated that mobile operators have offered compensation to more than 75 million subscribers for poor network quality following a regulatory directive requiring restitution in locations where performance fell below required standards.
The regulator is conducting an independent review to determine whether all eligible subscribers received proper compensation.
The compensation scheme, provided through automatic airtime credits for verified service failures dating back to November 2025, requires no individual claims from consumers.
For many subscribers, however, airtime credits do little to offset the broader economic and personal toll of unreliable connectivity.
Emeka Douglas, a subscriber, recounted how poor network quality nearly turned a medical emergency into a tragedy when he was unable to transfer funds to a hospital during his wife’s surgery.
Douglas noted that his brother in the United States eventually sent funds directly to the hospital’s account after local banking channels failed.
Janet Okoye, a small business owner, said unreliable connectivity severely affected her business after service disruptions on her Airtel and Globacom lines led clients to cancel orders.
Teniola Adeyemi, a university student, highlighted dropped calls as a major concern, stressing that recent tariff increases ought to reflect in better service quality.
Grace Eze, an Abuja-based media professional, explained that fluctuating network connectivity once delayed a lead news story intended for her editor in Lagos, resulting in an official query over late submission.
Pressure on national networks is driven by both expanding subscriber numbers and rising usage intensity.
Active telephony subscriptions in Nigeria rose from 182.2 million in January 2026 to over 187 million by April, according to NCC data. MTN leads the market with 96.4 million subscriptions, followed by Airtel with 64.7 million and Globacom with 23.2 million.

ipNX Collaborates with ICT Stakeholders on the Future of Fibre-to-the-Home in Nigeria @ ATCON Forum
ipNX Nigeria joined other stakeholders across the telecommunications ecosystem as they convened at the Association of Telecommunications Companies of Nigeria (ATCON) Critical Conversation Forum on Fibre-to-the-Home (FTTH) to deliberate on practical solutions to the challenges affecting broadband infrastructure deployment and the future of fibre connectivity in the country.
The forum, themed “Fibre to the Home in Nigeria: Addressing Challenges, Strengthening Standards and Ensuring Sustainable Deployment,” was held at the Radisson Blu Hotel, Lagos, and brought together representatives from government agencies, telecommunications operators, regulators, infrastructure providers, industry associations, and the media to foster dialogue around policies and collaborative actions needed to accelerate Nigeria’s broadband ambition.
Delivering the keynote address virtually, the Executive Vice Chairman of the Nigerian Communications Commission (NCC), Dr. Aminu Maida, described Fibre-to-the-Home as a critical enabler of Nigeria’s digital future.
“FTTH is uniquely positioned to meet Nigerians’ next phase of data demand. The quality of our broadband will increasingly shape the competitiveness of our businesses, the growth of our digital industry and the opportunities available to our citizens,” he said.
Dr. Maida also stressed the importance of protecting telecommunications infrastructure, noting that damage to fibre networks carries significant economic consequences.
“We must uphold deployment standards. Nigeria needs fibre that is properly installed, properly documented, and properly protected.”
Speaking during the opening session, ATCON President, Mr. Tony Emoekpere, underscored the strategic importance of FTTH in achieving Nigeria’s broadband penetration targets while calling for greater public awareness around protecting communications infrastructure.
“This forum is critical because Fibre-to-the-Home is the technology that will enable the country to achieve full broadband penetration. We all depend on communication infrastructure, and it must be protected.”
Drawing a comparison with power infrastructure in the country, he added:
“If somebody comes to your neighbourhood to tamper with your transformer or power cables, everybody will come out. The same thing needs to apply for communications infrastructure. When we see people damaging fibre cables, we should raise an alarm.”
The forum also highlighted successful collaborative initiatives at the state level. Speaking on infrastructure management, Director-General of the Oyo State Infrastructure Management and Control Agency (OYSIMCA), Mr. Adebayo Akande, shared how the agency is addressing fibre theft, vandalism, and promoting shared infrastructure among operators.
He explained that encouraging operators to utilise common pole infrastructure along shared routes would reduce unnecessary duplication, minimise infrastructure damage, improve urban aesthetics, and optimise investment across the sector.
Similarly, Managing Director of the Edo State Information and Communication Technology Agency (ICTA), Mr. Eghosa Urhoghide, advocated stronger collaboration among operators, regulators, government institutions, road maintenance agencies, and host communities.
He emphasised that strict adherence to NCC deployment standards remains essential to ensuring the long-term sustainability and resilience of Nigeria’s telecommunications infrastructure.
Representing ipNX on the panel discussion titled “Policy, Governance and Regulatory Alignment,” Mr. Segun Okuneye, Deputy Director, Strategic Business Initiatives, highlighted the need for stronger collaboration across the telecommunications ecosystem to unlock the full potential of fibre broadband in Nigeria.
According to him, sustainable fibre deployment extends beyond technology and investment to include policy consistency, stakeholder alignment, infrastructure protection, and shared responsibility.
“Achieving universal fibre connectivity requires more than deploying infrastructure, it requires sustained collaboration between operators, regulators, government agencies and host communities.
“When policies are aligned, deployment standards are consistently enforced, and critical infrastructure is protected, we create an environment where investment thrives and more Nigerians can enjoy reliable, high-speed broadband.
“At ipNX, we remain committed to working with all stakeholders to build resilient digital infrastructure that will support Nigeria’s economic growth for generations to come.”
Throughout the discussions, participants agreed that while Nigeria has made considerable progress in broadband expansion, addressing recurring issues such as fibre vandalism, right-of-way challenges, inconsistent deployment practices, infrastructure duplication, and limited public awareness will require stronger partnerships and coordinated industry action.
The forum concluded with a shared commitment among stakeholders to strengthen industry standards, encourage infrastructure sharing, improve policy implementation, and promote greater public appreciation of telecommunications infrastructure as critical national assets deserving of protection.
For ipNX, participation in the ATCON Critical Conversation Forum reinforces our company’s ongoing commitment to supporting industry-wide initiatives that advance broadband penetration, strengthen digital infrastructure, and accelerate Nigeria’s journey towards a more connected and digitally inclusive future.
