Neurophysiology: CNS Components, Basal Ganglia Flashcards
In the frontal lobe the neurons for voluntary motor control are found in the … and arranged in a ….
Precentral gyrus; homunculus
What occurs with damage to the frontal lobe (4)?
- loss of motor control on the contralateral side
- Deterioration of higher intellectual abilities
- Loss of planning and problem solving skills
- Loss of initiative and personality (frontal lobotomY)
The neurons for cutaneous and muscle sensations are located in the … (location of the sensory homunculus).
post-central gyrus
What occurs with damage to the parietal lobe (2)?
- Decreased spatial orientation
2. Loss of body image on the contralateral side
What are the functions of the Temporal Lobe (3)?
- Auditory cortex for hearing
- Memory of sights and sounds
- Emotional behavior
What occurs with damage to the temporal lobe?
Kulver-Bucy Syndrome
Seizures in the temporal lob may produce ….
hallucinations of sights, sounds, smells, etc.
What is responsible for conscious perception of vision, correlation of visual images with previous visual experiences and other sensory stimuli?
Visual cortex
What are the functions of the Insular Lobe? (2)
- Memory encoding
- Integration of some sensory with visceral (autonomic) responses (i.e. coordination of cardiovascular responses to stress)
What layer in the cortex has the function of, structural and connections between cortical layers?
Layer I

Layer II & III
What layer in the cortex has the function of, receives thalamic input?
Layer IV
What layer in the cortex has the function of, sends cortical output to brainstem and spinal cord?
Layer V
What layer in the cortex has the function of, sends output to thalamus?
Layer VI
