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’s commitment to digital innovation took center stage at MarkHack 4.0, the annual marketing and technology conference held at Landmark Event Centre, Victoria Island, Lagos, on Friday, May 23, 2025, with the theme ‘Experience Ignited: Fueling the Customer’s Journey’.

In a celebration of innovation, technology, and storytelling, the company also took home the award for Best Use of Data in a Marketing Campaign at the Nigeria MarTech (MarkHack 4.0) Awards Night. This award recognizes brands that have successfully transformed data into compelling narratives and actionable insights to meaningfully engage their audiences.
Akinbulejo Onabolu, Senior Manager, Segment Management, Enterprise Business at MTN, joined a panel to discuss the power of immersive technologies on consumer behaviour. Drawing from MTN’s launch of its 5G Digital Experience Centre in Abuja last year, Onabolu highlighted the rapid evolution of immersive technologies such as Virtual Reality (VR) and Augmented Reality (AR) stating “Our 5G centre is a sandbox for our customers to come and see how technology can shape things. At the launch event, we unveiled a smart city to customers, clients and dignitaries in attendance, with gaming and other tech experiences.”
On the intersection of data, AR and VR, he added: “Co-creating with MTN takes our minds to a platform where different partners, companies and creators can bring their buildings, products and businesses for people to see via augmented reality and connectivity, just swiping through and following through that journey.
“As a part of impacting our customer’s lives, a few years ago, we also played around with the Metaverse and we ended up creating some of our back-office processes with some of our customer journeys on augmented reality and virtual reality such that a customer somewhere can engage with a virtual agent to solve real life problems and integrating that back into our operating systems. As an organization, at a lot of our events, you will find a lot of AR and VR experiences.”
Speaking on how MTN is embedding immersive technology into its day-to-day operations, he explained that the company is prioritizing both internal capability development and external engagement. “85% of our organization has undergone extensive training on AI and that already is a great addition to our daily lives. We’re using it to do things differently, developing user journeys and brainstorming different things. In terms of Augmented Reality and Virtual Reality, we are working with organizations to develop training programs which we use internally.”
He described the bases for this tech as stable connectivity, high bandwidth, high speed and low latency. “Over the past year, we’ve doubled our 5G capacity across the entire country. Wherever you are, you’ll probably start to pick up 5G. With our FibreX service, we’re going way beyond connectivity to create the systems and platforms to support the ecosystem, AR and VR. In addition to this, we’re also engaging regulatory systems to start to tease this out and build the proper governance.”
The session, moderated by Daniel Adeyemi, Managing Editor at Condia Business, also featured insights from leaders in FMCG, consulting, and global marketing, all underscoring the transformative potential of immersive technologies for Africa’s future.
MTN Nigeria has announced a massive capital expenditure (CAPEX) drive for 2025, nearly doubling its investment to almost 900 billion Naira, as it seeks to significantly enhance network service quality in major cities like Lagos and Abuja and extend improvements to other areas.

This financial commitment, up from a combined total of approximately 440 billion Naira spent in 2023 and 2024, was detailed by MTN Nigeria CEO, Dr. Karl Toriola, during a recent interview on Arise TV.
Toriola highlighted that a key focus of the increased CAPEX will be on “putting additional capacity in a city like Lagos, particularly in Abuja, where you have a lot of buildings coming up, you need additional sites because there are coverage issues.”
Beyond these critical urban centres, the investment aims to bolster network resilience and ensure power stability for its infrastructure nationwide. This includes proactively addressing site outages by ensuring timely payment for operational necessities such as diesel for generators, a persistent challenge in the Nigerian operating environment
The CEO outlined the comprehensive nature of the upgrade process, which involves “placing orders formally, opening letters of credit, and then the equipment gets shipped in and installed.” He added that where necessary, MTN will be “acquiring new sites” and “laying fiber to the base station to create better stability.”
While the immediate CAPEX is geared towards improving existing service quality and capacity, this investment aligns with MTN’s broader goals, which include enhancing financial inclusion in underserved rural areas, suggesting a long-term vision for network expansion and service improvement that extends beyond metropolitan areas.
Customers are expected to begin experiencing the positive impact of these investments with a “significant improvement in quality of service” anticipated by the end of the second quarter or early in the third quarter of 2025, according to Toriola.
