b. Failure to respond to stimuli on the right side of their body
c. Scotoma on the left visual field.
d. Asomatognosia, failure to recognize your own body parts

Step 1
Posterior parietal cortex
Posterior parietal cortex located between the the visual cortex. The main function of this part of brain is planned movement, attention, and spatial reasoning.
Parietal cortex responsible for many action and damage in the posterior parietal cortex can cause various type of sensorimotor deficit, including inaccurate grasping and reaching to an object, spatial relationships, control of eye movements and inattention. The two main consequences of damage in PPC is hemispatial neglecte and apraxia.

Group of answer choices Parasympathetic (sympathetic) innervation of the sphincter pupillae stimulates pupil dilation. Photoreceptors in the retina are of two types: rods and cones. Eye color is determined by that of the iris. A. Light striking the fovea centralis goes unnoticed and is commonly called the "blind spot". B. Light entering the eye passes through the cornea, anterior chamber, pupil, lens, and vitreous body, from outer to inner.(posterior only) C. Movement of the extrinsic muscles of the eye is controlled by the autonomic (optic nerve) nervous system. D. Because lacrimal fluid ultimately enters into the nasal cavity, people often sniffle when they cry. F. The adjustability of the lens allows the eye to focus on nearby objects.arrow_forwardThe _____ project information via the internal capsule to sensory cortex of the cerebral hemispheres. a.
