Figure 7. Interaction between locomotion-related inputs and hippocampal theta rhythm.

Schematic illustration of the effect of phase on neuronal integration of two oscillatory signals. A neuron (triangle) receives two oscillatory inputs with similar frequency. One input (in red) is phase locked to the head acceleration signal. The other (in blue) is phase locked to the hippocampal theta rhythm. The amplitude of the outputs (violet traces) depends on the phase difference of the inputs.
