Study Links Hippocampus to Control of Skilled Movements

The hippocampus, traditionally linked to memory, also plays a crucial role in skilled actions like typing, handwriting, and playing music. This study challenges the long-held belief that motor skills are exclusively managed by motor regions like the basal ganglia and cerebellum.

Hippocampus Distinguishes Urgent from Future Goals

Researchers discovered how the brain prioritizes immediate and distant goals. Their study found that the hippocampus processes urgent goals faster and differently than future goals. This insight could help understand psychiatric disorders like depression, which affect goal-setting abilities. The findings reveal crucial differences in brain activity and behavior related to goal prioritization.

Hippocampus Shrinkage Linked to Cognitive Decline Beyond Alzheimer’s

A new study indicates that hippocampal shrinkage in the brain is associated with cognitive decline, independent of amyloid-beta plaques, a key marker of Alzheimer's disease. The study suggests that neurodegenerative diseases other than Alzheimer's contribute to cognitive decline.

Unlocking the Dual Memory Codes of the Hippocampus

Researchers have distinguished between two vital memory tasks housed in the hippocampus: one that remembers associations and another that predicts based on past events. The study used optogenetics to isolate one memory function without affecting the other.
