The Human Brain : From Neurone to Nervous System

ENTORHINAL CORTEX AND SPATIAL NAVIGATION


  1. We orient ourselves and navigate our way through our environment using a process called spatial navigation, by which we can identify our current location and plan our movements. This process is based on out ability to map our environment and identify and remember landmarks.

  2. This process involves the creation of a 'cognitive map' that allows potential routes and optimal paths to a new position in our environment to be identified.

  3. Recently the neurones responsible for spatial navigation and the cognitive map have been found within the entorhinal cortex of the temporal lobe of experimental animals .

  4. The entorhinal cortex is intimately involved in navigating ourelves through our environment, and in selecting appropriate routes to a desired place.

  5. Key Words: Hippocampus; Entorhinal Cortex; Spatial Navigation
