Topic: spatial scales

Cells in the rodent hippocampal (HP) formation contain representations of space and time. In entorhinal cortex (EC), spatial (grid) cells are organised along a hierarchical gradient with smaller spatial scales dorsal and larger scales ventral (homologous to a posterior-anterior axis in humans). Recent models suggest these patterns of cellular activity might be the consequence of a more general mechanism that optimally represents the structure of possible sequences in the world. If so, it should be possible to find similar signatures for arbitrary (non-spatial) sequences. Using extracellular re
