Neuroscience Flashcards
forebrain
top part of the brain
midbrain
middle of the brain
hindbrain
lower part of the brain
cerebral cortex (cortical structures)
the outer surface of the brain associated with higher level processing
frontal lobe
involved in high-order cognitive planning, decision making, and impulse control
motor cortex
structure in the frontal lobe involved with planning and coordinating movement
pre-frontal cortex
structure in the frontal lobe involved with higher-level cognitive functioning
parietal lobe
processes sensory information
somatosensory cortex
structure in the parietal lobe that processes information from sensory receptors
temporal lobe
responsible for hearing, memory, emotion, and language
auditory cortex
structure in the temporal lobe that processes auditory information
occipital lobe
processes visual information
primary visual cortex
structure in the occipital lobe that interprets incoming visual information
longitudinal fissure
divides each hemisphere of the brain
corpus callosum
bundle of fibers that connect the two hemispheres and allow them to communicate
gyri
patterns of folds or bumps
sulci
grooves
Broca’s area
responsible for language production
Wernicke’s area
responsible for speech comprehension
Broca’s aphasia
loss of ability to produce speech and language
Wernicke’s aphasia
loss of ability to understand incoming speech
What are the four main indicators of Broca’s aphasia?
- halting speech
- repetition of phrases
- disordered grammar and syntax
- comprehension intact
What are the four main indicators of Wernicke’s aphasia?
- fluent speech
- little spontaneous repetition
- adequate grammar and syntax
- comprehension not intact
subcortical structures
structures that lie below the cerebral cortex
thalamus
sensory relay station of the brain where senses are routed before being sent to processing areas
hypothalamus
regulates homeostatic processes and responsible for the 4 F’s
What are the four F’s that the hypothalamus controls?
fighting, feeding, fleeing, f*cking
amygdala
plays a role in emotional processes and ties emotional meaning to memories
hippocampus
essential structure for learning and memory
anterograde
difficulty forming new memories
retrograde
difficulty remembering old memories
