Question

Which of the following is the common characteristic in the receptive fields of the ganglion cells in the retina, the LGN, and striate cortex neurons in layer IVC? a. Center surround b. Elongated bar of light moving across the receptive field c. Optimal orientation of a bar of light d. Radial column of cells from pia to white matter e. A and D

Answer 1

The answer is option E (A and D)

Step-by-step explanation:

The receptive field is a area of a sensory space that can elicit neuronal responses when stimulated or engaged.

The ganglion cells have circular receptive fields, similar to the LGN and striate cortex neurons which have the receptive fields of the neurons radially aligned in these pathways. Another common feature is with the center-surrounded opposition or antagonism.

Hence, the common characteristics are center surrounded opposition and radial columns of cells from pia to white matter.

Answer 2

Answer;

(A) center surround anatgonism

Step-by-step explanation:

The receptive field of a ganglion cell in the retina of the eye consists of feedback from all the photoreceptors that synapse with it, and the receptive field for a cell in the brain is generated by a group of ganglion cells.

Retinal ganglion cell receptive field as a retinal region from which the frequency of action potentials could be increased. Ganglion cells are the first neurons in the retina thatrespond with action potentials
