Basal Gang
What is the Striatum made up of?
putamen and caudate nucleus
This ascending pathway carries pain and temperature sensation.?
STT
This structure is where nasal retinal fibers cross?
optic chiasm
This syndrome presents with resting tremor, rigidity, bradykinesia, and postural instability.
PD
This nucleus is divided into internal (GPi) and external (GPe) segments.
globus pallidus
Fibers of the spinothalamic tract cross the midline through this spinal cord structure?
anterior white commissure
This thalamic nucleus relays visual information to the visual cortex?
lateral geniculate nucleus (LGN)
Damage to the corticospinal tract results in these upper motor neuron signs.
spasticity, hyperreflexia, clonus, and a positive Babinski sign?
What receptor is excited by dopamine in the indirect pathway?
D2 receptor
Primary sensory neurons of all ascending pathways have their cell bodies located here.?
dorsal root ganglion (DRG) or posterior horn of the spinal cord.
This thalamic nucleus relays auditory information to the auditory cortex.
medial geniculate nucleus (MGN)
This hereditary disease results from degeneration of the caudate nucleus.
Huntington disease?
Activation of the direct pathway causes this change in thalamic activity?
increased thalamic excitation of the motor cortex (disinhibition)
This tract coordinates head and eye movements in response to visual and auditory stimuli?
tectospinal tract
These otolith organs detect linear acceleration and head position relative to gravity?
utricle and saccule
A lesion of the subthalamic nucleus produces this hyperkinetic movement disorder.
Hemiballismus?
