Humans create spatial maps whenever they go somewhere. Neurons called place cells inside the hippocampus fire individually while a person makes their way through an environment. This was first discovered in rats, when the neurons of the hippocampus were recorded. Certain neurons fired whenever the rat was in a certain area of its environment.
The Morris water navigation task is a classic test for studying spatial learning and memory in rats [28] and was first developed in 1981 by Richard G. Morris for whom the test is named. The subject is placed in a round tank of translucent water with walls that are too high for it to climb out and water that is too deep for it to stand in.
The Morris water navigation task was conceived by Richard G. Morris (then at the University of St Andrews) in 1981 as an alternative to the radial maze. [10] The test was developed to study spatial learning and how it differed from other forms of associative learning. [11]
Spatial view cells are used by primates for storing an episodic memory that helps with remembering where a particular object was in the environment. Imaging studies have shown that the hippocampus plays an important role in spatial navigation and episodic memories. [7]
The hippocampus plays important roles in the consolidation of information from short-term memory to long-term memory, and in spatial memory that enables navigation. In humans, and other primates the hippocampus is located in the archicortex, one of the three regions of allocortex, in each hemisphere with neural projections to the neocortex.
Amygdalohippocampectomy is a surgical procedure for the treatment of epilepsy.It consists of the removal of the hippocampus, which has a role in memory, spatial awareness, and navigation, [1] and the amygdalae, which have a role in the processing and memory of emotional reactions, [2] both structures forming part of the limbic system of the brain.
Typically, the hippocampal formation is said to included the dentate gyrus, the hippocampus, and the subiculum. [2] The presubiculum, parasubiculum, and the entorhinal cortex may also be included. [3] The hippocampal formation is thought to play a role in memory, spatial navigation and control of attention.
His work on spatial navigation argues that the hippocampus is important for the spatial behavior known as dead reckoning, the relatively automatic process of determining the shortest way back to a starting location after an outward trip. Dead reckoning is the navigation strategy used by Columbus to reach the America’s and return to Spain.
