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.
Study identifies a different set of individual neurons in the medial frontal cortex that is responsible for memory-based decision making. The findings have implications for the treatment of Alzheimer's disease, schizophrenia, and other disorders associated with problems in cognitive flexibility.
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.
Researchers identified an abnormal link between the autonomic and central nervous system via communication between the heart and parts of the prefrontal cortex in women with generalized anxiety disorder.
Researchers have found significant changes in the brain make up of fetuses and newborn rats exposed to allergens during pregnancy.
Early-life exposure to antibiotics may impact brain signaling pathways associated with social behavior and pain regulation. Young mice treated with antibiotics had reduced expression of receptors that mediate endorphin, oxytocin, and vasopressin signaling in the frontal cortex.
While adults build integrated memories based on existing inferences, children can separate memories they later compare to make inferences as they go.
Researchers discover a gene already associated with longevity also improves memory and learning. The findings could help develop new treatments for cognitive decline.
