4. 25 Cerebrum 4 Flashcards
cerebral cortex: layers overview
multiple layers, each with a different cellular structure
3 cell types of the cerebral cortex
- pyramidal and fusiform cells
- stellate cells
Which cells of the CC are the outputs?
pyramidal and fusiform cells
Which cells of the CC are the interneurons?
stellate cells
“map” of the cortical regions
Brodmann’s areas
What do Brodmann’s areas designate?
general related functions of cortical areas
- associated with each other but don’t work alone
Everything in the brain is accomplished by
neural networks
What are the 5 major areas of the CC?
- primary sensory
- secondary sensory
- motor planning
- primary motor
- association areas
Flow of information
primary sensory »
secondary sensory »
motor planning »
primary motor
primary sensory area
receives sensory info
secondary sensory area
analyzes info from primary sensory and categorizes it
motor planning area
organization/planning of movements (aka premotor area)
primary motor
- descending pathways that start with the cortex
Where do both primary sensory and motor planning neurons project?
primary motor cortex
association areas impact
- behavior
- sensation (more emotional)
- emotion processing/generation
- memory retrieval
frontal lobe
