- What is visual cortex?arrow_forwardWhat is a sensory modality?arrow_forwardYou are driving at night on a two lane road, and you see a bright light. The light pass through your pupil, and your lens concentrates the light at retina. This stimulates the visual pathway. Your visual association center processes the signal from your eye and determines the lights is from a flashlight that an old lady is holding while crossing the street. Your visual association center sends a signal to your primary motor cortex, which sends a signal down the lateral corticospinal tract. This signal then proceeds down the spinal cord, out the posterior gray horn of the spinal cord, and out the ventral roots of efferent motor neurons. The motor signal travels from the sacral plexus and out towards the sciatic nerve. To answer this question, number the following steps in the correct order starting with the signal exiting the sciatic nerve. Number in order from 1-15 ______The cycle repeats and now many muscle fibers in the gastrocnemius begin to contracts in unison. _____Calcium ions…arrow_forward
- Unilateral Cerebral strokes can cause deficits in motor control, somatic sensation and vision. However, they do not cause deficits in hearing. The explanation for this is: Auditory information does not reach the cortex Auditory information only goes to one hemisphere. Auditory information goes to both hemispheres How are the outer segments of photoreceptors positioned? between bipolar cells and horizontal cells in the outermost layer of the retina in the ganglion cell layer farthest from the pigment epitheliumarrow_forwardDo blind people experience REM sleep?
