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.

Terra Moves to Expand in African Drone Sector, Secures $22m Funding

Olugbenga Agboola, Flutterwave CEO has joined a $22 million funding extension for Nigerian defensetech start-up Terra Industries as Africa’s fast-growing drone and security technology sector begins to attract capital far beyond traditional venture circles.

The round was led by Lux Capital, with participation from Agboola through Resilience17 Capital and returning investors including 8VC and Nova Global.

It follows an $11.75 million raise just weeks earlier, bringing Terra’s total funding to $34 million as the company accelerates expansion into high-risk security markets.

Terra, founded in 2024 by 24-year-old chief engineer Maxwell Maduka and CEO Nathan Nwachuku, builds autonomous drones and surveillance systems designed to protect critical infrastructure such as energy facilities, logistics corridors and industrial sites. The startup says it is already safeguarding assets worth billions of dollars while securing early federal and commercial contracts.

Agboola’s involvement highlights a broader shift in African tech investment patterns. While fintech has long dominated venture flows, escalating infrastructure sabotage and terrorism threats have elevated demand for locally developed security hardware.

“Nigeria’s drone ecosystem is rapidly evolving from hobbyist and mapping use cases toward industrial monitoring, border surveillance and energy protection, areas increasingly seen as foundational to economic stability.

“This is about backing infrastructure security at scale. Africa’s growth depends on resilient systems that protect critical assets,” said Agboola.

Terra CEO Nwachuku is adamant that locally engineered systems are better suited to African operating conditions. “We are building tools designed for the realities on the ground. Security technology should not always be imported when local innovation can respond faster and more effectively,” he stated.

Lux Capital partner Brandon Reeves underlined that the investor appetite, which has drawn fintech heavyweight interest such as Agboola, reflects rising cross-sector confidence in African defense technology as a commercial category. “Security is a prerequisite for economic growth,” he said.

“As Terra ramps production and expands regionally, its funding milestone illustrates a wider transformation. Drone and autonomous security platforms are no longer peripheral experiments but emerging pillars in Africa’s technology landscape, where fintech leaders and venture capital converge around safeguarding the infrastructure powering the continent’s next growth phase,” said Reeves

The company’s response follows NDPC’s investigation into Temu’s data processing practices.

In a statement to Nigeria CommunicationsWeek, Temu stressed its dedication to local and international data protection standards, noting ongoing communication with the regulator. “At Temu, protecting user privacy and data security is a top priority. We are committed to complying with applicable laws and regulations in our data practices,” the statement read.

Temu further affirmed: “We can confirm that Temu has received the inquiry and is engaging with the Commission. We will continue to engage in open and constructive dialogue with the NDPC to address any questions or concerns.”

Under Dr. Vincent Olatunji’s leadership, NDPC has ramped up scrutiny of foreign digital platforms to safeguard Nigerian citizens’ personal data—from contact details to financial information—ensuring transparent and secure handling. For e-commerce giants like Temu, managing vast consumer data volumes demands strict regulatory alignment to sustain operations and trust in Africa’s biggest economy.

Industry observers view Temu’s proactive stance as a savvy bid to ease tensions, mirroring Nigeria’s firm handling of platforms like X (formerly Twitter) and fintechs. This engagement underscores NDPC’s rising clout, compelling investors and foreign entrants to prioritise data compliance costs.

Nigeria CommunicationsWeek sees Temu’s approach as a model for global retailers eyeing Nigeria’s booming digital retail sector through 2026.
