Topic: local auditory cues

During spatial navigation, hippocampal place cells rely on visual inputs to map space, but other sensory modalities, such as odour, can also be effectively used (doi: 10.1093/cercor/bht239). Although rodents are nocturnal and short-sighted, little is known about the role of other sensory modalities as substrates for place fields. Here, we recorded electrophysiologically from place cells in the hippocampal CA1 region of adult male rats while they explored a round empty field arena in darkness and in the absence of reliable tactile, olfactory, and visual cues. We compared place cell behaviour un
