What is neuroscience? Neuroscience is the scientific study of nervous systems. Neuroscience can involve research from many branches of science including those involving neurology, brain science, neurobiology, psychology, computer science, artificial intelligence, statistics, prosthetics, neuroimaging, engineering, medicine, physics, mathematics, pharmacology, electrophysiology, biology, robotics and technology.

Midlife Cortisol Levels Linked to Alzheimer’s Risk

A new study finds that elevated cortisol levels in midlife are linked to increased brain amyloid deposition—a key marker of Alzheimer’s disease—specifically in post-menopausal women. Researchers tracked 305 cognitively healthy individuals over 15 years and discovered that high cortisol predicted amyloid buildup later in life, but only among women who had gone through menopause.

Babies Fight COVID Differently Than Anyone Else

Infants hospitalized with severe COVID-19 mount an immune response that looks entirely different from that of adults or older children. Researchers found both interferon responses and inflammation were elevated simultaneously—something never before observed in other viral infections.

AI Chatbots Mirror a Human Brain Disorder

Researchers have found a surprising similarity between the way large language models (LLMs) like ChatGPT process information and how the brains of people with Wernicke’s aphasia function. In both cases, fluent but often incoherent output is produced, suggesting rigid internal processing patterns that can distort meaning.

Tylenol Targets Pain Through Unexpected Endocannabinoid Pathway

A new study reveals that acetaminophen (Tylenol) relieves pain by reducing levels of an endocannabinoid called 2-AG, rather than increasing it as previously thought. This discovery challenges decades-old assumptions about how pain relief works and may open the door to designing safer, more targeted medications.

Calm Your Mind: Choose Mindfulness by Anxiety Type

Mindfulness is well known for its calming effects, but researchers now propose that different types of mindfulness practices may be more effective for specific types of anxiety. A new framework suggests that focused attention meditation may benefit those who worry chronically, while open monitoring may help individuals with hypervigilance and physical symptoms.

This shows different animals in a forest setting.

Hidden Patterns Shape Animal Behavior Across Species

Despite vast ecological differences, animals from meerkats to hyenas appear to follow a shared behavioral architecture in how they switch between activities. By tracking movement patterns with accelerometers and using machine learning, researchers discovered that the longer an animal stays in one behavior—like resting or foraging—the less likely it is to switch, a pattern known as a “decreasing hazard function.”

Personality Could Help Predict Bipolar Disorder

New research suggests that personality testing could help tailor treatment for people with bipolar disorder by predicting who is more likely to experience recurrent depression or struggle with daily life functioning. Analyzing data from over 2,500 individuals, researchers identified combinations of personality traits—called personality styles—that either increase or protect against long-term mental health risks.

Alzheimer’s Disrupts the Whole Body, Not Just the Brain

Alzheimer’s disease is traditionally seen as a brain disorder, but new research using fruit flies reveals that it also affects organs and tissues throughout the body. Scientists created an Alzheimer’s Disease Fly Cell Atlas to profile gene expression across 219 cell types in flies expressing human Alzheimer’s proteins.

Silent Switches in DNA Gave Rise to Human Intelligence

Despite sharing over 98% of our DNA with chimpanzees, humans possess strikingly advanced cognitive and emotional abilities. A new study reveals that rapid shifts in gene regulation—rather than changes in protein-coding genes—may explain this leap.

Astrocytes Control Behavior Through Slow Brain Signaling

Astrocytes, once thought to be mere support cells, are now shown to play a leading role in regulating behavior by modulating neuronal activity through slow biochemical circuits. In zebrafish, researchers discovered that astrocytes respond to norepinephrine by releasing ATP, which is then broken down into adenosine—an important neuromodulator that signals neurons to stop swimming when progress is futile.

Clues in Spinal Fluid Could Unlock Early FTD Diagnosis

Frontotemporal dementia (FTD), a common form of early-onset dementia, is often misdiagnosed due to its overlapping symptoms with psychiatric and neurological disorders. In a new NIH-funded study, researchers identified key protein changes in spinal fluid that may serve as the first specific biomarkers for FTD in living patients.

Psychedelics May Shift Brain Power to the Right Hemisphere

A new theory suggests that psychedelics promote empathy, insight, and psychological flexibility by making the brain’s right hemisphere temporarily dominant over the left. Known as HEALS—Hemispheric Annealing and Lateralization Under Psychedelics—this model proposes that psychedelics disrupt the typical hierarchy between hemispheres, releasing the more holistic, emotionally intelligent right side from left-brain control.
