Brain structure and mood improve when people spend time outdoors. This has positive implications for concentration, memory, and overall psychological wellbeing.
Combining EEG data and MRI brain scans, researchers discovered how, during sleep, the hippocampus sends memory information it has stored throughout the day to the cerebral cortex, allowing for memory consolidation.
Researchers have identified three areas of the posterior cerebral cortex that bridge the brain's perception and memory systems.
Apoptosis plays a critical role in brain development as it influences the thickness of layers in the cerebral cortex, variety, and layer cell density. Alterations in how cells perform division and apoptosis lead to the development of abnormal cortical structures as seen in a variety of neurodevelopmental disorders, including autism.
People with depression often experience problems with visual perception. Researchers report issues with visual perception are likely linked to information processing differences in the cerebral cortex.
A large-scale meta-analysis reveals men and women's brains do have slight differences. However, the differences are due to brain size and not sex or gender. Researchers say brain differences between men and women are small and inconsistent once an individual's head size is accounted for.
People who suffer from obesity have stronger connections between brain areas associated with the motivation to eat and the rewarding effect of food consumption. Additionally, researchers found noted differences in the thickness of the cerebral cortex of obese test subjects.
Gray matter damage associated with multiple sclerosis progression may be caused by inflammatory reactions that lead to synaptic loss.
High resolution imaging reveals the human cerebellum is 80% of the area of the cortex. The findings indicate this area of the brain likely grew larger as human behavior and cognition evolved.
