Behavioral Neuroscience Quiz #4

Prefrontal Cortex

Selects the appropriate behavior and its target, using a combination of bodily and external information

Premotor Cortex

Combines information needed for movement programming (target & location) 

Supplementary motor area

Assembles sequences of movements; coordinates movements between the two sides of the body

Primary motor cortex

Executes voluntary movements by organizing the activity of specialized cells; adds force and direction control

Basal ganglia

Uses info from secondary areas (thalamus) and somatosensory cortex to integrate and smooth movements (learning movement sequences)

Cerebellum 

Maintains balance, refines movements, controls compensatory eyes movements (learning motor skills) 

Posterior parietal cortex

Supplies motor area with information about location of body parts in relation to objects in space

Where does sensory info go?

Somatosensory cortex

Where is sensory info relayed?

PPC

PFC

PPC relays information to; conscious decision making

Pre-motor cortex

PPC relays information to; programming action plan

Supplemental Motor Area

PPC relays information to; assembles sequences

Primary motor cortex

PPC relays information to; executes signal to move

Where does the basal ganglia receive info from?

Primary & secondary motor areas; Somatosensory cortex

Main neurotransmitters of the Basal Ganglia

Gaba (inhibitory) & Dopamine (movement, reward)

Caudate nucleus

Connects the putamen to other basal ganglia structures
