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.

$2 Saliva Test Could Help Detect Depression and Schizophrenia

Scientists have developed a portable biosensor that can detect levels of BDNF, a protein linked to mental health conditions such as depression, schizophrenia, and bipolar disorder. The flexible, low-cost device analyzes a drop of saliva in under three minutes, offering a fast, affordable, and noninvasive diagnostic tool.

How Chemotherapy Triggers Nerve Damage, and How to Stop It

A new study reveals that chemotherapy-induced nerve pain arises from a stress response in immune cells that triggers inflammation and neurotoxicity. Researchers found that activating a cellular stress sensor called IRE1α causes nerve damage and pain during chemotherapy, but blocking it prevents both in mice.

Epigenetic Switch to Turn Memories On and Off Created

Researchers have shown for the first time that flipping an epigenetic “switch” in specific memory-holding neurons can directly alter memory strength. By targeting the gene Arc—which helps neurons adjust their connections—scientists used CRISPR-based tools to either boost or silence its activity in engram cells within the hippocampus.

How Neurons Feel Force: Uncovering the Physics of Touch

A groundbreaking study reveals how neurons sense and transmit mechanical forces across their membranes—a key to understanding touch, movement, and development. Using precision laser-based optical tweezers, researchers discovered that tension travels faster in touch-sensing neurons than in movement-sensing ones.

How the Brain’s Ion Gates Open and Close

New research reveals how tiny electrical gates in the brain, known as NMDA receptors, control learning, memory, and neuron survival. Using cryo-electron microscopy, scientists captured atomic-level images showing how a natural neurosteroid, 24S-HC, holds these channels wide open, while a synthetic compound locks them partially shut.

Your Brain “Zones Out” After Poor Sleep To Clean Itself

New research shows that during moments of lost focus after poor sleep, the brain releases a wave of cerebrospinal fluid (CSF)—the same cleansing process that normally occurs during deep sleep. Using simultaneous EEG and fMRI scans, scientists found that these fluid pulses occur precisely when attention lapses, suggesting the brain is attempting to catch up on missed “housekeeping.”

Football Players Show Subtle Brain Differences Linked to CTE Risk

Brain scans of former football players revealed subtle differences in brain grooves compared to men who never played contact sports, possibly marking early signs of chronic traumatic encephalopathy (CTE). Researchers found that players had shallower grooves in a key frontal region previously associated with CTE and that years of play correlated with structural changes in another area of the brain.

When Using AI, Users Fall for the Dunning-Kruger Trap in Reverse

A new study reveals that when interacting with AI tools like ChatGPT, everyone—regardless of skill level—overestimates their performance. Researchers found that the usual Dunning-Kruger Effect disappears, and instead, AI-literate users show even greater overconfidence in their abilities.

Hunger Hormone and Blood Flow Team Up to Guide New Brain Cells

Scientists have discovered that blood flow helps direct the movement of newly formed neurons in the adult brain, revealing a surprising link between circulation and brain cell migration. Using advanced imaging, researchers found that neurons travel faster along high-flow blood vessels, and that the hunger hormone ghrelin boosts this migration by activating movement within the cells.

Dopamine Boost Makes People More Patient

In one of the largest studies of its kind, researchers found that increasing dopamine levels with L-DOPA made people slightly more willing to wait for larger, delayed rewards—reducing impulsive decisions by about 20%. The study challenges earlier research suggesting that dopamine increases impulsivity, showing instead that it promotes patience and long-term thinking.

Gene That Controls How Sensitive You Are to Alcohol Discovered

Researchers have discovered that a gene called CHRNA3 plays a key role in determining alcohol sensitivity, helping explain why some people tolerate alcohol better than others. When this gene was mutated, subjects were slower to avoid alcohol and consumed more of it, showing reduced sensitivity to its calming effects.

Daily Light and Sound Therapy May Slow Alzheimer’s Decline

A long-term study found that daily 40Hz light and sound stimulation may help slow cognitive decline in people with late-onset Alzheimer’s disease. After two years of treatment, participants maintained stronger cognitive performance than typical Alzheimer’s patients and showed reduced levels of tau protein, a key disease biomarker.
