brain structures and functions Flashcards
cerebellum
motor functioning, smooth and coordinated movements
medulla
cardio, breathing, skeletal muscle tone
midbrain
neural relay stations and coordinate reactions to sensory events
tectum
neural relay center
superior colliculi
visual
inferior colliculi
auditory
reticular formation
sleep, attention
substantia nigra
produces dopamine
broca’s area
ability to speak (damage results in lack of fluency, knowing words but unable to form them)
frontal lobe
executive functioning, decision making
parietal lobe
somatosensory cortex
Temporal lobe
auditory
wernicke’s area
auditory, ability to make sense, damage leads to “word salad”
occipital lobe
visual
basal ganglia
movement- affects parkinson’s
amygdala
motivation, emotion
hippocampus
memory (damage results in perpetual present)
thalamus
relay center for sensory info
hypothalamus
motivation, pleasure
right hemisphere
spatial tasks, emotional processing, judging time
left hemisphere
language, like reading and writing
corpus callosum
bridge between left and right hemisphere
split brain can occur
- Agenesis of corpus callosum is from birth
2. when the corpus callosum has been cut to prevent epilepsy
Right hemisphere controls left side of movement
left hemisphere controls right side of movement
