ABSTRACT
The model
The knowledge on cell physiology of the distal retina gives an ability to represent the functioning of cone -horizontal cell - bipolar neural network as a whole. Six signal operations are combined in the model:
phototransduction operation (i.e. signal transformation from light into electrical response in the photoreceptor);
chemical synaptic transmission from photoreceptors to second order neurons;
electrical coupling between horizontal cells;
nonlinear (amplifying) properties of horizontal cell non-synaptic membrane;
the feedback from horizontal cells to photoreceptors in triad synapses;
dynamics of the bipolar neuron.
