WebWhat represents the remaining 30%? These are a heterogeneous class of cell with highly specific responses. One example is a ganglion cell with chromatic tuning. This neuron has a simple receptive field, with a single light-sensitive “center” region. Blue light falling on the cell’s receptive field excites it; yellow light inhibits it. WebThe receptive field has two distinct regions: an excitatory region and an inhibitory region. 8. c. a bar of light oriented at a particular angle. 9. a. an off-center retinal ganglion cell. 10. a. one eye. Step-by-step explanation 1. A sensory area known as the receptive field activates a receptor cell or neuron.

WebMost retina ganglion cells have center-surround receptive fields, where the center may be either ON or OFF while the surround is the opposite. We clarify the functional roles of the receptive field structure, on the basis of the modern theory of natural data processing. It is suggested that the retina shares the principal mechanism and ... WebA relatively large area of the sensory surface could affect that firing rate of any one cell. In addition, stimulation of any one region would affect the firing rate of several cells. This animation follows procedures similar to those actually used by Kuffler (1953) to determine the receptive fields of retinal ganglion cells. What is not ...

WebMost neurons in the retina and thalamus have small receptive fields that have a very basic organization, which resembles two concentric circles. This concentric receptive field structure is usually known as center-surround organization. On-center retinal ganglion cells respond to light spots surrounded by dark backgrounds like a star in a dark sky.
