B). Precentral sulcus
C). Precentral gyrus
C). Precentral gyrus
What is the function here?

What is this gyrus called?
A). Precentral sulcus
B). Superior temporal gyrus
C). Post central gyrus
C). Post central gyrus
What is the function here?
A). Primary Motor
B). Somatic sensory
C). Primary auditory
B). Somatic sensory
Which lobe is this?
A). Parietal
B). Temporal
C). Occipital
A). Parietal
What are the functional differences between primary and
association cortex and which has the bigger area?
Association cortex is
usually more advanced and does higher order
processing than the primary cortex which is the first point of input
e.g - Visual cortex and association
visual cortex - association does all of
primary and faces, objects,
recognition, depth, binocular,
patterns
The parietal lobe performs mostly
A). Sensory processing
B). Visual processing
C). Motor processing
A). Sensory processing
Wernickes area is an important area for :
A). Processing visual stimuli
B). Complex body image inputs
C). Language comprehension
C). Language comprehension
The primary visual cortex is found in cerebral cortex of which lobe?
A). Frontal
B). Occipital
C). Temporal
B). Occipital

What fluid filled structure has a similar shape to the caudate nucleus and is closely associated with it?
A). fourth ventricle
B). subarachnoid space
C). lateral ventricle
C). lateral ventricle
Which component of the basal ganglia structures is degenerated in Parkinson’s disease
A). substantia nigra
B). subthalamic nucleus
C). putamen
A). substantia nigra
Which elements of the basal ganglia make up the dorsal striatum?
A). nucleus accumbens and olfactory tubercle
B). globus pallidus and substantia nigra
C). putamen and caudate nucleus

In the David and Goliath conundrum, if the giant has found it difficult to detect the presence of
Goliath on both left and right sides which parts of those visual pathways that are visible on the
ventral brain may be affected?
A). Optic nerves
B). Optic chiasma
C). Optic radiation
