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.

Ketogenic Diet May Stabilize Mood in Young People with Bipolar

Researchers are launching a multi-site pilot study to assess whether a ketogenic diet, alongside standard medications, can stabilize mood symptoms in young people with bipolar disorder. The 16-week trial will involve 40 participants aged 12-21, who will follow a ketogenic diet while their mood symptoms, metabolic markers, and adherence to the diet are monitored.

How CBD Modulates THC’s Impact on the Brain

Researchers have identified how CBD interacts with cannabinoid receptors to mitigate the negative effects of THC, the psychoactive component of cannabis. Unlike THC, which fully activates the receptor and causes side effects like memory loss and addiction, CBD acts as a modulator, fine-tuning receptor activity.

Sleep Strengthens Emotionally Charged Memories During Non-REM Phase

Researchers have discovered that positive emotions enhance perceptual memories during sleep, particularly in the non-REM stage. Using mice, they found that memories linked to rewarding experiences lasted longer than neutral ones.

How the Brain Overcomes Instinctive Fear and Adapts to New Threats

Researchers have identified brain mechanisms that help animals suppress instinctive fear responses when threats prove harmless over time. Using a visual threat model in mice, they found that specific areas of the visual cortex are necessary for learning to override fear, but not for storing the memory. Instead, the ventrolateral geniculate nucleus (vLGN) retains these learning-induced memories, regulating fear suppression.

Ancient Ear Muscles Reactivate When We Struggle to Listen

Humans have vestigial ear muscles that once helped our ancestors focus on sounds. New research shows these muscles still activate when we strain to hear in noisy environments. Scientists used electromyography to measure auricular muscle activity in people listening to an audiobook with distracting background noise.

Imaging Reveals Gut-Brain Connection in Alzheimer’s Disease

Scientists have used advanced X-ray phase-contrast tomography (XPCT) to uncover how gut health may influence Alzheimer’s disease. The study found structural changes in the gut of Alzheimer’s-affected mice, revealing abnormalities in intestinal cells, neurons, and mucus secretion.

Genetics, Not Maternal Sickness, Drives Autism Risk

A large study analyzing over 1.1 million pregnancies found no strong evidence that maternal health conditions during pregnancy cause autism. Instead, nearly all previously reported associations between maternal diagnoses and autism could be explained by genetic or environmental factors.

Unhealthy Diet Linked to Faster Biological Aging in Young Adults

Diets high in processed meat, fast food, and sugary drinks accelerate biological aging, even in young adults. Researchers measured biological age using epigenetic clocks, which track gene regulation changes over time. Participants with a diet rich in fruits and vegetables showed slower aging, suggesting dietary choices influence how quickly the body ages.

How the Brain Adapts to New Sensory Contexts

New research reveals how the brain rapidly adapts to sensory changes using a feedback loop between the olfactory cortex and the olfactory bulb. Scientists trained mice to associate rewards with specific sounds and smells, then switched the rules to test their adaptability.

Blood Test May Predict Postpartum Depression Through Hormone Levels

Women who develop postpartum depression (PPD) may have distinct neuroactive steroid levels during the third trimester of pregnancy. A study found that those with PPD had lower levels of pregnanolone, which reduces stress, and higher levels of isoallopregnanolone, which increases stress.

Oral Bacteria Linked to Stroke Risk

A new study finds that the bacteria Streptococcus anginosus is more abundant in the saliva and gut of people who have had a stroke and is associated with a higher risk of death and major cardiovascular events. Researchers compared 189 stroke patients with 55 non-stroke participants, finding that this bacterium increased stroke risk by 20%.

How Large Social Circles Foster Trust

A new study challenges the belief that larger groups reduce cooperation, showing instead that flexible social connections enhance teamwork. Researchers found that in a prisoner’s dilemma game, participants in bigger groups cooperated more frequently, despite memory limitations.
