文摘

Subicular units code space in a heterogeneous manner. We found place cells, barrier-related and grid-like units. These last had spike waveforms similar to axonal recordings. Place cells did not show firing related to physical boundaries in the baseline recordings. Barrier-related cells fired in relation to boundaries. This group included BVC but not all barrier-related were BVC. Firing remapping detected suggests that units firing might be re-set, by a path integration mechanism.
