Cortex
Deficits in language comprehension
What do association tracts do?
share information within one hemisphere
Job of the hippocampus
Memory
In the peripheral nervous system, a tract is called a:
nerve
Measures brain waves
Electroencephalography (EEG)
Patient has lesion in primary motor cortex
Three commissural tracts
corpus collosum, posterior commissure, anterior commissure
What does the medial geniculate nucleus do?
It is part of the auditory pathway sending information from the auditory nerve to Heschl's gyrus.
Anterior corticospinal
decussates in spinal cord, important for axial movement
Less expensive, quicker imaging than MRI
Computerized tomography
Patient has lesion in premotor cortex
planning movement
Function of arcuate fasciculus
T/F The thalamus is important for sending motor and sensory information
True
Lateral corticospinal tract
decussates in medulla, important for limb movment
X-ray procedure that x-rays blood vessels to view blockages
Cerebral angiography
Patient has lesion in prefrontal cortex
Deficits in executive function - decision making, attention, inhibition, etc.
Function of uncinate fasciculus
memory and emotions
What makes up the striatum?
caudate nucleus and putamen
Vestibulospinal tract
balance and posture, goes from the vestibular system to the spinal cord
Used to view tracts in brain
Diffuse tensor imaging
Patient has lesion in supramarginal gyrus
Deficits in sound-symbol correspondence
Function of inferior longitudinal fasciculus
visual processing and language comprehension
T/F The cerebellum has three lobes
True, posterior, anterior, and flocculonodular lobe
Medial reticulospinal tract
goes from the reticular nuclei to the spinal cord, important for increasing muscle tone and facilitating muscle movement
Two types of imaging that use radioactive tracers
PET, SPECT
