Mouse study reveals slow-wave brain activity, which is indicative of sleep and resting states, is controlled by the claustrum. The synchronization of active and silent states across the brain via the slow waves contributes to consciousness.
Heart insufficiency has a negative impact on gray matter in the brain. Weak heart function was linked to decreased gray matter in areas of the brain associated with memory and learning, including the hippocampus and parietal medial cortex. This may increase the risk of Alzheimer's disease.
Study discussed the benefits of using psychedelics as an antidepressant option for those with depression.
Prosopagnosia, or "face-blindness", involves an entire network, not just one area of the brain. The findings may shed light on poor facial processing abilities associated with autism.
The left and right brain areas are more similar in those with ASD. Reduced asymmetry was identified in cortical thickness across various brain regions in those on the autism spectrum.
Nineteen gene sets have been identified that contribute to at least five psychiatric disorders. The gene sets were associated with ADHD, ASD, bipolar disorder, major depressive disorder, and schizophrenia.
LATE, a form of dementia that appears in the oldest-old is often mistaken for Alzheimer's disease, but the brain pathology is very different. The protein TDP-43 appears to play a significant role in the development of LATE. The neurodegenerative disease may progress more gradually than Alzheimer's, but when combined with Alzheimer's disease (a common combination), appears to cause a more rapid decline than either would alone.
