Medial nuclear group function?
(and external thalamic reticular formation extension)

project information from reticular formation to relay nuclei and then to the cerebral cortex.

Function of pars intermedia?

produces melanocyte stimulating hormone MSH
causes melanocytes to secrete melanin which darkens skin. it increases during pregnancy.

Pineal body function?

secretes melatonin
modulate sleep patterns
don’t really know what it does
might regulate sexual maturity
Calcifies in adolescence

Substania Nigra associated with what disease?

parkinson’s disease. degenerative where you loos cells.

Perfectly

Subthalamus function?

exert inhibitory influence and prevent dyskinesia-hemiballismus (bad movement)

Brodmanns area 1,2,3

Post central gyrus

Brodmanns area 4

pre central gyrus

Pre-central gyrus

primary motor area (cortex) or primary motor strip
originates most corticospinal tract motor fibers
voluntary fine digital movement

Premotor cortex

brodmanns area 6 control of trunk and poximal muscles

Supplementary motor area (SMA)

motor planning plans the sequence of movements from memory rather than movements guided by visual cue

Frontal eye fields

brodmanns area 8 voluntary control of extraocular movements

Prefrontal cortex function?

CEO of brain executive control personality emotions and control problem solving reasoning decision making memory

Brocas Area

pars triangularis and P opercularis drive motor (expressive) speech dominant on teh left side 80-95% of people lession-expressive aphasia (common from stroke) can still use profanity with expressive aphasia

Post Central Gyrus

primary somesthetic sensory area. I.E primary receiving area for general sensation. Brodmanns area 1,2,3 follow homuncular pattern

General sensation

pain temperature tactile seense fine touch and pressure stereognosis 2 point discrimination kinesthetic sense (conscious proprioception) vibration

VPL?

Ventral posterior lateral nucleus general sensory fibers from body coming in and directed to relay nucleus of thalamus

VPM?

Ventral posterior medial nucleus gets sensory info coming in from the face.

General sensory association cortex

process general sensory information in parietal lobe

Inferior parietal lobule made of?

supramarginal gyrus angular gyrus

Supramariginal gyrus function?

integratoin center, provides sensory tactile feedback to guide motor tasks. Speech comprehension wernicke's area (temporal lobe and wernicke's area)

Disorder of supramarginal gyrus cause?

dypraxia/apraxia receptive aphasia

Dyspraxia

Basically can't process tactile information. ideamotor: know what to do but cannot do it ideational: does not know what to do or how to do it.

Supplementary motor area dysfunction

can't perform sequence of movements from memory

angular gyrus function

reading association

agular gyrus dysfunction

dyslexia - any reading disorder agraphia - cant write acalculia - can't do simple calculations finger agnosia - can't identify fingers that are held up left-right disorientation

How much of brain is association cortex?

80-85%

Primary visual area receives information from?

Thalamic visual relay nuclei (lateral geniculate nuclei)

Cortical blindness

issue with primary visual cortex. cant see at all.

association cortex blindness

you can actually see, but can't tell what it is.

Visual association cortex

occipital lobe outside of primary visual area

function of visual association cortex

integration and interpretation of visual information

Visual agnosia

you can see, but don't know what you are looking at.

Function of anterior transverse temporal gyri

primary auditory area gets send information from medial geniculate body (relay nucleus) of thalamus.

Wernikie's speech area

speech association area dominant on left for most people. supramarginal gyrus and angular gyrus?

Arcuate fasiculus

fibers connecting broca's area to wernicke's area speeds up process
