cortex

This digital reconstruction of the entire mouse cortex gives researchers a new way to explore brain function by recreating conditions such as Alzheimer's or epilepsy inside a virtual environment.

The brain's ability to interpret the visual world does not depend solely on its advanced outer layer, the cortex.

During the task, the scientists monitored the electrical signals from hundreds of neurons in the prefrontal cortex, the brain region involved in decision-making and complex thought.

The brain-related markers included a thinner cerebral cortex, white matter changes linked to vascular disease, and reduced or uneven blood flow.

Several studies have identified decreases in gray matter volume in key regions such as the frontal and temporal cortices and the hippocampus, which play major roles in memory and decision-making.
