Cognitive maps beyond the hippocampus.
We present a conceptual framework for the role of the hippocampus and its afferent and efferent structures in rodent navigation. Our proposal is compatible with the behavioral, neurophysiological, anatomical, and neuropharmacological literature, and suggests a number of practical experiments that could support or refute it. We begin with a review of place cells and how the place code for an env...
متن کاملCognitive maps and the hippocampus.
Following a familiar route and finding a novel route in a familiar environment depend on different cognitive processes and representations. A recent study by Hartley et al. begins to identity the neural basis of route following and wayfinding in humans. Their study also raises important questions about the functions of the hippocampus.
متن کاملThe human hippocampus: cognitive maps or relational memory?
The hippocampus is widely accepted to play a pivotal role in memory. Two influential theories offer competing accounts of its fundamental operating mechanism. The cognitive map theory posits a special role in mapping large-scale space, whereas the relational theory argues it supports amodal relational processing. Here, we pit the two theories against each other using a novel paradigm in which t...
متن کاملThe human hippocampus beyond the cognitive map: evidence from a densely amnesic patient
We tested a densely amnesic patient (P9), with bilateral hippocampal damage resulting from an autoimmune disorder, and 12 age- and sex-matched controls on a series of memory tasks designed to characterize allocentric spatial learning and memory abilities. We compared P9's ability to perform spatial memory tasks with her ability to perform non-spatial, color memory tasks. First, P9's performance...
متن کاملBeyond memory, navigation, and inhibition: behavioral evidence for hippocampus-dependent cognitive coordination in the rat.
Injecting tetrodotoxin (TTX) into one hippocampus impaired avoidance of a place defined by distal cues while rats were on a slowly rotating arena. The impairment could be explained by a deficit in memory, navigation, or behavioral inhibition. Here, we show that the TTX injection abolished the ability of rats to organize place-avoidance behavior specifically when distal room and local arena cues...
