The hippocampal CA1 field processes spatial information, but the relative importance of intra- vs. extra-hippocampal sources of input into CA1 for spatial behavior is unclear.
Webb14 apr. 2024 · Author summary The hippocampus and adjacent cortical areas have long been considered essential for the formation of associative memories. It has been recently suggested that the hippocampus stores and retrieves memory by generating predictions of ongoing sensory inputs. Computational models have thus been proposed to account … WebbWe performed circuit-specific optogenetic inhibition and found that the hippocampal CA3 subregion is the crucial target of LC projections during the encoding of a novel context. Furthermore, we show with activity-dependent labeling and in vivo calcium imaging that LC inputs are necessary to provide stable neuronal representations of the context.
