As the first generation that interacted with digital technology reaches an age where dementia risks emerge, scientists have asked the question: Is there a correlation between digital technology use and an increased risk of dementia? With the phrases “brain rot” and “brain drain” circulating on social media, it would appear that most people would assume the answer is yes.

However, a new study in Nature Human Behavior by neuroscientists at Baylor University and the University of Texas at Austin Dell Medical School reveals the opposite—digital technologies are actually associated with reduced cognitive decline.

The study, “A meta-analysis of technology use and cognitive aging,” was sparked by the ongoing concern about the passive activity of digital technologies and their relation to accelerating risks of dementia. Study co-authors are Jared F. Benge, Ph.D., clinical neuropsychologist and associate professor of neurology at Dell Medical School and UT Health Austin’s Comprehensive Memory Center within the Mulva Clinic for the Neurosciences, and Michael K. Scullin, Ph.D., associate professor of psychology and neuroscience at Baylor.

The world is full of tips and tricks on how to live longer—some say it’s about eating clean, others swear by cutting stress. But when someone who has crossed the 100-year mark speaks, the world listens. Dr John Scharffenberg, a preventive medicine specialist who lived a rich and active life into his 100s, offered a perspective that turns many popular beliefs on their head.

His message was simple, sincere, and backed by years of real-life observation. The secret, he said, isn’t food or relaxation—it’s something far more practical and often overlooked.

Characterizing the intelligence of biological organisms is challenging yet crucial. This paper demonstrates the capacity of canonical neural networks to autonomously generate diverse intelligent algorithms by leveraging an equivalence between concepts from three areas of cognitive computation: neural network-based dynamical systems, statistical inference, and Turing machines.

Researchers in optics and brain and cognitive science are investigating whether neurons can transmit light in a manner similar to fiber-optic communication channels. Neurons, specialized cells in the brain and spinal cord that form the central nervous system, are known to communicate through elec

The newly discovered SLYM membrane segregates clean and dirty CSF, supporting the brain’s immune defenses and glymphatic system, paving the way for targeted treatments and deeper understanding of brain diseases. The human brain, with its intricacies ranging from neural networks to fundamental bio

Human brains make synaptic connections throughout much of childhood, and the brain’s plasticity enables humans to slowly wire them based upon experiences, contrary to how chimpanzees develop. Humans and chimpanzees share 98.8% of the same genes, but scientists have been looking for what drives the unique cognitive and social skills of humans.

A new study, which was published today in Genome Research, that examined brain samples from humans, chimpanzees, and macaques, collected from birth up to the end of their life span, has found some key differences between the expression of genes that control the development and function of synapses, which are the connections between neurons through which information flows.

Scientists from the Max Planck Institute of Biological Cybernetics are studying how different brain regions cooperate during memory. While testing monkeys with images for visual stimulation, they recorded electrical activity both in a visual area and in the frontal part of the brain. Their research
