Why taxi drivers may hold the key to Alzheimer’s?

What does the hippocampus?

Abstract. Hippocampus is a complex brain structure embedded deep into temporal lobe. It has a major role in learning and memory. It is a plastic and vulnerable structure that gets damaged by a variety of stimuli. Studies have shown that it also gets affected in a variety of neurological and psychiatric disorders.

What is the posterior hippocampus?

Abstract | The precise functional role of the hippocampus remains a topic of much debate. The dominant view is that the dorsal (or posterior) hippocampus is implicated in memory and spatial navigation and the ventral (or anterior) hippocampus mediates anxiety-related behaviours.

What is the posterior hippocampus used for?

The posterior hippocampus is preferentially connected to the retrosplenial and posterior parietal cortices and is thought to be involved principally in cognitive and spatial processing.
