Expand description

Direction-selective retinal ganglion cell (DS-RGC) with On/Off sub-types.

Models the centre-surround receptive field with temporal derivative for direction selectivity. On-centre RGC responds to light increments, Off-centre responds to decrements.

response = w_c · (I - I_prev) ± w_s · surround_inhibition spike if response > θ
