Subtle variations in brain structure during childhood are associated with early substance use, a new study reveals.
A six-hour sleep disruption in mice weakened fear memory consolidation and increased brain-derived neurotrophic factor mRNA levels.
New research reveals astrocytes, not just neurons, are crucial for cannabinoid receptor-mediated brain plasticity during development.
For girls, early harsh parenting might impact brain circuits involved in emotion regulation, increasing the likelihood of behavioral difficulties later in childhood.
A study found that infants with persistent regulatory problems (e.g., sleeping, crying, feeding difficulties) had poorer peer relationships in adulthood and increased functional connectivity in the allostatic-interoceptive brain system.
Western diets harm adolescent brain blood flow within weeks, research in mice reveals. Omega-3 fatty acids, like those in fish oil, showed a surprising ability to protect against this damage.
New research shows the ventral hippocampus scales its activity according to anxiety levels. Like an "anxiety meter," this brain region's neurons become more active as anxiety increases.
Even a short digital detox can have a real effect on your brain. Research shows that just three days away from your smartphone changes activity in brain regions related to impulses and rewards.
Anxiety can change how children's brains respond to happy faces, but in surprisingly different ways for boys and girls, according to a new study.
New research in mice reveals a brain region, the lateral habenula, as central to risk preference. Scientists found activity in this area reflects a mouse's risk choice even before deciding. Signals from the hypothalamus are essential for this brain process.
Youth with anxiety show a distinct brain activity pattern when viewing negative scenes, a study found. Brain scans revealed they engage a state linked to deeper emotional processing, suggesting anxiety may intensify negative feelings.
Scientists have developed a new method to understand autism by studying individual variations in brain connectivity.
A recent study has revealed that a well-known brain chemical, serotonin, plays a surprising role in reducing anxiety by acting in a brain area once thought to be solely responsible for controlling movement.
In adolescent girls with anorexia, increased somatomotor cortex activation to fearful faces after weight recovery suggests heightened anxiety-driven motor preparation.
Regular aerobic exercise reduces disease markers of Alzheimer's in rat brains, a new study finds. Scientists observed less amyloid, tau, and iron accumulation, offering hope for combating this devastating disorder.
