Neuralink First: Patient Uses Brain Implant to Make YouTube Video

Neuroscience, Science /

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 […]

Study Finds 15 Early Dementia Risk Factors

Neuroscience, Science /

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

New Study Links Attention Shifting in the Brain to Autism’s Social Challenges

Neuroscience /

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

Study Finds Some Voices Are Naturally More Memorable

Neuroscience, Science /

“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

Sleep Boosts Memory: Study Finds Neural Reorganization During Rest

Neuroscience, Science /

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

Scientists Evaluated AI for Detecting Cognitive Decline. The Findings Were Surprising

Neuroscience, Science, Uncategorized /

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 Trick Neurons Into Thinking They’re Inside a Living Brain

Neuroscience /

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

Expert Identifies Irregular Brain Wave Patterns as Potential Indicator of ADHD

Neuroscience /

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

Adults Generate New Brain Cells, Which Play a Role in Enhancing Learning Through Listening

Neuroscience, Science /

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

Brain Stars Function as Tiny Storage Units for Our Memories

Neuroscience, Science /

Recent research into how “brain stars” (astrocytes) store memories has reshaped our understanding of memory retention in the brain. Previous Beliefs About Memory and Neurons Scientists at Baylor College of Medicine have been examining the role of astrocytes, star-shaped cells in the brain that function as tiny storage units for memories. These cells work in
