The Hippocampus as a Cognitive Graph
A theory of cognitive mapping is developed that depends only on accepted properties of hippocampal function, namely, long-term potentiation, the place cell phenomenon, and the associative or recurrent connections made among CA3 pyramidal ceils. It is proposed that the distance between the firing fields of connected pairs of CA3 place cells is encoded as synaptic resistance (reciprocal synaptic ...

متن کاملThe Hippocampus as a Cognitive Map … of Social Space
The traditional view of the hippocampus is that it creates a cognitive map to navigate physical space. Here, in this issue of Neuron, Tavares et al. (2015) show that the human hippocampus maps dimensions of social space, indicating a function in the service of navigating everyday life.
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 کاملCognitive 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...
