Frontal Lobes
Question | Answer |
---|---|
What are the subdivisions of the frontal cortex? | Motor, premotor, prefrontal, anterior cingulate |
Functions of the motor cortex? | specifies elementary movements such as those of the mouth and limbs, controls movement force and direction, its cells projects to subcortical motor structures such as the basal ganglia, the red nucleus as well as the spinal cord |
What areas does the premotor cortex contain? | The supplementary motor cortex (dorsal region) and 3 major premotor sectors: the dorsal and ventral premotor cortex and the inferior frontal gyrus (Broca's area) |
What are the functions of the premotor cortex? | Active for choosing movements from its movement lexicon, contains mirror neurons that recognize other's movements and selects similar or different actions, as does the Broca's area; can influence movements directly through corticospinal projections or ind |
What are the three regions of the prefrontal cortex? | The dorsolateral prefrontal cortex, the orbitofrontal cortex, the ventromedial prefrontal cortex. |
What are the functions of the prefrontal cortex? | receives input from mesolimbic dopomine cells in tegmentum - NB role in regulating how prefrontal neurons react to stimuli - contributes to emotional states |
