Hippocampus spatial
Webb7 juni 2024 · 1. INTRODUCTION. The original formulation of the cognitive map theory specified that the hippocampus is part of a “memory system, which contains information about places in the organism’s environment, their spatial relations, and the existence of specific objects in specific places” (Ref. 1, p. 2; emphasis added).The basic idea was … WebbWhile robust place-cells are found in the mammalian hippocampus, much less is known about spatial coding in the hippocampus of birds. Here we used a wireless-electrophysiology system to record single neurons in the hippocampus and other two dorsal pallial structures from freely flying barn owls ( Tyto alba ), a central-place …
