Abstract

Eliav et al., (2018) recently reported hippocampal-entorhinal spiking in bats occurring preferentially at specific phases of nonrhythmic extracellular voltage fluctuations. This disentanglement of phase coding from continuous oscillations raises new questions about the importance of rhythms for neuronal coordination.

Keywords: bats; entorhinal cortex; grid cells; hippocampus; nonrhythmic fluctuation; oscillations; phase coding; phase precession; place cells; theta.
