High school reunions often highlight how differently people age. Some individuals remain mentally sharp and physically active well into their later years, while others begin to experience frailty or memory decline much sooner than anticipated. “The way we age biologically doesn’t always match our chronological age,” said Ahmad Hariri, a psychology and neuroscience professor at […]

The first nonverbal Neuralink patient to receive the implant is showing how he uses the technology—narrating and editing a YouTube video through brain signals. Brad Smith is the third person globally to receive a Neuralink brain chip implant and the first individual with ALS to undergo the procedure. Amyotrophic lateral sclerosis (ALS), or Lou Gehrig’s

Although dementia typically affects older adults, hundreds of thousands of individuals receive a diagnosis of young-onset dementia (YOD) each year, and a major 2023 study provides valuable insights into its causes. Key Lifestyle and Health Factors in Young-Onset Dementia Previous studies have focused on genetics, but this team identified 15 lifestyle and health factors linked

Human interaction plays a crucial role in development, beginning at birth. However, for children with autism spectrum disorder (ASD), this social engagement is disrupted early in life. In fact, research shows that children with ASD exhibit reduced interest in social stimuli as early as their first year—a trait that ultimately impacts long-term cognitive and emotional

“Memorability” describes how likely a stimulus—such as an object, face, or sound—is to stay in memory after someone encounters it. Recent psychological studies have explored whether some stimuli naturally stand out in memory, making them easier to recall than similar ones. Researchers at the University of Chicago recently explored the memorability of voices, with their

A full night’s sleep strengthens memory by reinforcing newly learned information. This process is crucial for animals as well, as recalling the location of food sources is vital for survival. Researchers study this function of sleep in the lab by training mice and rats with different memory tasks to explore their environment. In spatial learning

It’s been just under two years since OpenAI introduced ChatGPT to the public, allowing anyone online to collaborate with an AI on tasks ranging from poetry and schoolwork to drafting letters for their landlord. Today, ChatGPT is just one of several advanced large language models (LLMs) capable of responding to basic queries in a way
Scientists Evaluated AI for Detecting Cognitive Decline. The Findings Were Surprising Read More »
Neurons, the brain’s essential cells, form intricate networks by exchanging signals, enabling learning and adaptation. Researchers at Delft University of Technology (TU Delft) in the Netherlands have created a 3D-printed environment that closely resembles real brain tissue. Using nanoscale pillars, they replicate the soft, fibrous structure that supports neurons. This innovation provides a more accurate
Scientists Trick Neurons Into Thinking They’re Inside a Living Brain Read More »
Children with attention deficit hyperactivity disorder (ADHD) are not lazy, undisciplined, or lacking manners. Instead, their brains develop and function differently, marked by unique neurological activity patterns and neurochemical imbalances. These differences classify ADHD as a neurodevelopmental disorder rather than a behavioral issue. The Neurological Basis of ADHD The neurological variations in ADHD manifest as

Your brain can still produce new neurons in adulthood, but how do these rare additions support cognitive function? Neurons, the cells responsible for brain function, are mostly formed before birth. While early life sees the bulk of brain development, certain regions continue generating neurons into adulthood, albeit at a slower pace. Scientists debate whether adult
