- 3rd side (hint)
|
Supplementary Motor Area (SMA) |
- output to cortcospinal pathway -sequence specific for neurons - DAMAGE IN MONKEYS= deficits in bimanual coordination |
SMAC |
|
|
Premotor Area (PMA) |
- sends fewers outputs to spinal cord than SMA -triggered by external sensory events -important for visually guided movement - tells our body to move |
PMAM |
|
|
Corpus Callosum |
-attaches left and right brain |
|
|
|
Left Brain |
Language |
LL |
|
|
Right Brain |
Visospatial Skills |
RV |
|
|
Split Brain Syndrome |
- typically when a surgeon severs corpus callosum -now brain hemispheres must work alone -potentially genetic |
|
|
|
Broca's Area |
- Speech Production |
BS |
|
|
Broca's Aphasia |
- non-fluent aphasia - broken speech |
BB |
|
|
Wernicke Area |
- understanding language and comprehension |
|
|
|
Wernicke's Aphasia |
- can speak, but sound drunk, no grammar |
|
|
|
Apraxia |
a disorder of learned, skilled purposeful movement not related to muscle paralysis or comprehension deficits |
|
|
|
Ideational Apraxia |
inability to evoke appropriate action representation from long-term memory |
|
|
|
Ideomotor Apraxia |
inability to translate the appropriate innovatory patterns into action |
|
|
|
Down Syndrome |
- speech in right hemisphere - not a good thing, hemisphere is not optimized for speech production - corpus callosum is more round and thinner |
|
|
|
Afferent Fibers (sensory) |
occupy the dorsal and external lateral portions of the spinal cord |
|
|
|
Efferent Fibers (motor) |
occupy the ventral and internal lateral portions of the spinal cord |
|
|
|
Propriospinal Neuron |
A neuron coming from the brain enters the spinal cord and sometimes synopsis with a propriospinal neuron |
