New paper from Ulanovsky's group: With brain recordings from🦇 flying in a 200m tunnel, the group discovered that place cells of CA1 exhibit dense spatial coding, i.e., multiple place fields, and cells of CA3 exhibit ultrasparse coding, i.e., one place field. www.nature.com/articles/s41...
The hippocampus exhibits a CA3-to-CA1 coding transformation that combines fast learning with an efficient, compressed neural code.
