biopsych Flashcards
homunculus
Graphic representation for the divisions of the brain
-> body w/in the brain
wernicke’s area
understanding of written + spoken language
left hemisphere posterior inferior to temporal lobe
Visual pathway
Retina-optic nerve-optic chaism-optic tract- lateral geniculate nucleus-optics radiation-visual cortex
Gyrus
raised ridges (worms) winding around the brain
Conduction Aphasia
inability to repeat simple phrases
Sulcus
small grooves dividing the gyri/gyrus
Cortical Blindness
loss of vision without causes
= bilateral lesions inside Occipital lobe
Primary Olfactory Cortex
interprets smell
-> only sensory info not routed
Arcuate Fascicules
white matter pathway connecting wernicke’s + broca’s area
= coordinated speech
Primary Gustatory Cortex
Main site involved w taste
-> specific neurons for sweetness, sourness, saltiness, bitterness
Olfactation + Gustation
olfact.=sensation of smell
gust=sensation of taste
Broca’s aphasia
can comprehend words can’t physically talk
Cerebellum
Coordination persicion + motor movements
location=inferior to transverse fissure
Limbic System
set of structures inside the brain
-> not separate system but collection of cerebrum
Primary somatosensory Cortex
involved w processing temp. pressure + pain
bodily awareness-> space + time
