Chapter 3: Fore brain parts Flashcards
thalamus
sensory pre processing/ sensory relay center
- output to primary sensory cortex
- input from sensory organs
basal ganglia
sensory association areas (performs movements to obtain rewards), and tied to pleasure centre
damage to basal ganglia can cause…
parkinson’s, tremors, loss of motor control
hypothalamus
regulates internal states, emotion and motivation, regulates sex, hunger, thirst, and body temp.
limbic system
emotion, internal states (smell, motivation, memory, evolved out of olfactory system)
what does the limbic system entail?
thalamus, hypothalamus, hippocampus, amygdala
amygdala
excitement, arousal and aggression, fear.
damaged amygdala’s lead to no detection of fear.
hippocampus
spatial memory, physical layouts/ mental maps
hippocampus damage
impaired forming new memories, old memories intact.
cerebral cortex involves what parts and controls what?
forebrain, cerebrum.
most highly developed area, allows advanced intellectual skills
What is the outer layer of the cerebrum called?
the cerebral cortex or bark
the lateralization of the cerebral hemispheres refers to what..
that we rely more on one half than the other
how do the hemispheres in the brain communicate?
via the corpus callosum
What is the corpus callosum comprised of?
a large band of nerve fibures (axons) connecting hemispheres
4 lobes of the cerebral cortex
frontal, parietal, occipital, temporal
parietal lobe controls…
sensory integration
occipital lobe controls…
visual processing
who discovered the motor cortex?
penfeild, simple and complex movements
What does the somatosensory cortex control?
touch, temperature, pain
What does the occipital lobe do?
it’s the visual cortex
what does the temporal lobe do?
hearing, understanding language, memory
if one were to experience hallucinations, what lobe in the brain would be acting up?
the temporal lobe
the temporal lobe controls hearing, understanding language, and memory. What ‘s the area that controls the understanding of language?
Wernicke’s area.
What is the Broca’s area?
language production
