Descriptive models summarize large amounts of experimental data compactly yet accurately, thereby characterizing what neurons and neural circuits do.
Descriptive Model of Receptive Field
Definition: Specific properties of a sensory stimulus that generate a strong respond from the cell.
Spot of light that turns on a particular location on a retina
Bar of light that turns on a particular orientation and location on the retina
Receptive fields in the retina are center-surround receptive fields in the retina, it either a on-center off-surround receptive field or off-center on-surround receptive field.
Retina passes the information to Primary Visual Cortex (V1) through Lateral Geniculate Nucleus (LGN). And V1 responds to oriented receptive field
