Figure 5. The synaptic depression time constants τ_ON and τ_OFF strongly influence movement direction coding by bursts and isolated spikes.

A) Directional bias computed from the full spike train as a function of τ_ON and τ_OFF. B) Directional bias computed from the burst spike train as a function of τ_ON and τ_OFF. C) Directional bias computed from the isolated spike train as a function of τ_ON and τ_OFF. D) Opposite direction selectivity index (ODI) as a function of τ_ON and τ_OFF. E) PSTH values near the maximum values in the left to right (blue arrow) and right to left (red arrow) directions for the full spike (purple), burst (green), and isolated (orange) spike trains for an example data point marked with a star in panel D. F) PSTH values near the maximum values in the left to right (blue arrow) and right to left (red arrow) directions for the full spike (purple), burst (green), and isolated (orange) spike trains for another example data point marked with a star in panel D.
