Document Summary
Knowing where and getting there: a human navigation network. Previous literature has found that damage to a rat"s hippocampal structure leads to severe. These findings have provided support for the notion that the hippocampus provides an allocentric representation of locations, or cognitive map (maguire et al. , 1998). The posterior parietal lobe has been implicated in providing complementary egocentric representations of locations. Other brain regions such as the dorsal striatum, have also been identified as possible elements in the navigation system. In humans, the function of the hippocampus has been emphasized for its role in memory and in particular, in declarative or episodic memory (o"keefe et al. , 1998). This stems from evidence that patients with damage to the hippocampal formation are amnesic, in which these patients are impaired on spatial memory tasks. Based on these results, it was speculated that there is a special role for the human hippocampus in spatial navigation analogous to that in the rat.
