Neuroimaging

Scientists have discovered two biologically distinct subtypes of autism using brain imaging. By studying both mice and humans, researchers linked reduced brain connectivity to synaptic function and increased connectivity to immune system activity.

Scientists have successfully replicated the restorative power of sleep in awake mice. By using targeted light stimulation to mimic deep-sleep brain rhythms, researchers relieved sleep pressure and rescued memory performance, offering new insights into how our brains reset.

Scientists have identified the biochemical links between stress and reduced sexual motivation. By studying fruit flies, they found that dopamine prolongs courtship suppression after confinement.

Scientists have discovered that astrocytes use stress hormones to lock in neural connections during early brain development. This breakthrough helps explain how critical periods of learning close and how early life stress might alter brain maturation.

A new study in BMC Psychology suggests stuttering is more than a physical speech disorder. Researchers found that adults who stutter experience differences in auditory brain processing and higher anxiety, which both scale with their stuttering severity.

Higher levels of an excitatory brain chemical can make individuals overly sensitive to their mistakes. New research shows that an exaggerated response to everyday errors helps explain the shared biological roots of anxiety and depression.

A new neuroimaging study reveals that the brain organizes autobiographical memories chronologically. Memories from similar periods of your life share similar neural patterns, showing how our minds physically map out our personal histories.

People who regularly use psychedelic drugs outside of clinical settings process threatening facial expressions more efficiently than nonusers, according to recent brain imaging research. The scans reveal distinct neural habits that might explain the enduring emotional benefits of these substances.

Published in Nature Medicine, new research suggests a brain-computer interface can empower a person with severe paralysis to converse and work from home. The device decodes brain signals into text and computer commands without needing daily expert assistance.

By combining connectome data with spatial gene expression maps, scientists have discovered how chemical gradients guide the wiring of the entire brain. The findings offer new ways to understand brain development and neurodevelopmental disorders.

Physical exercise is known to improve mental health. A new study reveals that a muscle-released protein called apelin travels to the brain during exercise, promoting neuron growth and alleviating depression.

A new study of retired athletes found that repetitive head trauma can lead to a "leaky" blood-brain barrier. This long-lasting damage allows immune cells to enter the brain, causing persistent inflammation and accelerating cognitive decline.

New research finds that high psychopathic personality traits are associated with a thinner outer layer of the brain in specific regions. This structural brain pattern was identical in men convicted of domestic violence and non-violent men.

A new longitudinal study reveals that specific brain wave patterns emerging around age nine can reliably predict whether a child will develop anxiety or depression during their teenage years, opening the door for proactive mental health interventions.
