Fig. 5. Impact of tonic activity in NGL processing. Relay cells and interneurons behave
tonic mode we get a better detectability of the edges of our stimulus. Time detection
of the edges of the stimulus is reduced as the membrane potential of relay cells and
interneurons is more tonic.
Fig. 6. Impact in bursting activity in NGL processing. Relay cells and interneurons
behave simultaneously in burst mode, there is a poor detectability of the stimulus
edges. The stimulus edges are best detected when the stimulus relay cells found in
tonic mode and interneuron in burst mode.
5 Discussion
Our model of the NGL indicates that this nucleus is probably performing some
relevant visual information tasks. Concretely, it provides a plausible explana-
tion of the functionality of the ON and OFF channel push-pull circuit. The
