Term
| What parts of the Frontal Lobe are associated with movement? |
|
Definition
• Primary motor cortex – helps initiate movement
• Motor association (premotor) cortex plans movements (gets information from the basal ganglia and cerebellum and passes the information to the primary motor cortex |
|
|
Term
|
Definition
| • Different areas of the neocortex which are divided based on cell type and how they connect to each other |
|
|
Term
|
Definition
• Primary Sensory area
• Touch, pain, temperature, taste
• Associated with VPL |
|
|
Term
|
Definition
| Primary motor cortex –involved in initiating motor movement |
|
|
Term
|
Definition
• premotor cortex – plans movements in every possible area
• receives information from other motor areas of the neocortex, integrates the info and advises area 4 |
|
|
Term
|
Definition
| • Frontal eyefields – coordinates eye movements, coordinates saccadic movements |
|
|
Term
|
Definition
• Broca’s area
• Motor function associated with speech
• Controls facial activities |
|
|
Term
|
Definition
• Prefrontal cortex
• Most primitive of neocortical areas
• Involved in personality
• Inhibits and coordinates reflexes |
|
|
Term
|
Definition
• Visual Association areas
• Get visual input coming from area 17
• Area 17 responds to dots of light; area 18 responds to lines; parts of area 19 respond to angles, and so on
• Complexity of information increases with motion away from area 17 |

Term
|
Definition
• Wernicke’s area
• Part of the auditory association area |
|
|
Term
|
Definition
• the association cortex of association cortexes
• Seems to get information from everywhere |
|
|
Term
| Classicially how many layers are there in the neocortex? |
|
Definition
|
|
Term
|
Definition
• Small stellate neurons
• Any info coming into the cortex synapses in layer 4
• Distributes info to other layers |
|
|
Term
|
Definition
• Lots of pyramidal neurons
• It’s the major output area of the cortex |
