basal ganglia or corpus striatum - component of "extrapyramidal
motor system"
location and components (caudate, putamen, globus pallidus)
connections
input from cortex-thalamus, substantia nigra of
midbrain (nigrostriatal pathway)
output to same areas and extrapyramidal descending
pathways discussed in spinal cord chapter
basal ganglia disorders
Parkinson's disease
what's wrong with the brain
(death of DA neurons of substantia nigra), who it is seen in
what are the symptoms
bradykinesia
tremor at rest
rigidity
flexed posture
trouble initiating movements
treatments
medications
pallidotomy
thalamotomy
deep brain stimulation
stem cell implants
cognitive deterioration or "bradyphrenia"
Parkinson's disease dementia or Lewy Body dementia
Huntington's disease
what's wrong with brain
(loss of neurons in caudate/putamen and cortex; who gets it)
CAG repeats
what are the symptoms
chorea
athetosis
dementia
treatments
Tourette's syndrome
symptoms
treatments
correlation with other
disorders
cranial nerves
the 12 pairs of nerves
what chunk of brain each connects to
what each nerve does
what you wouldn't be able to do if each were damaged
trigeminal dermatomes (opthalmic, maxillary, mandibular)
cranial nerve related problems
palsies or paralysis of 3 nerves related to eye
movement
trigeminal neuralgia (tic douloureux)
Bell's palsy (facial paralysis)
Meniere's disease
thalamus
general structure and location
major divisions and functions
functions as a relay station for messages heading
to cortex
"specific nuclei" of thalamus
those with sensory functions such as
ventral-posterior (VP
thalamus)
touch
lateral geniculate - vision
medial geniculate - audition
those with motor functions
VA and VL
regions of cortex specific nuclei send their
messages
to
"nonspecific nuclei" connect to association areas of cortex and/or
limbic
structures
anterior nuclei
medial nuclei
intralaminar and reticular nuclei
kinds of functions the nonspecific nuclei are
involved
in
seizure vs epilepsy
"primary" vs "secondary" epilepsy
generalized vs partial/focal epilepsy
characteristics of different types
generalized tonic-clonic or grand mal seizures
petit mal or absence seizures
simple partial seizures
complex partial seizures
temporal lobe or psychomotor
seizures
aura
automatisms
treatments for epilepsy
status epilepticus
