Frage 7
Frage
FC has connections to [blank_start]unimodal[blank_end] sensory areas [blank_start]and the motor cortex.[blank_end]
PFC has connections to [blank_start]multimodal[blank_end] areas[blank_start], e.g. the temporal association cortex.[blank_end]
Frage 8
Frage
The [blank_start]orbitofrontal[blank_end] cortex is involved in the bottom-up response to reward cues, the anticipation of rewards and the reaction to them.
The PFC might play a role in top-down self-regulation but this is controversial and the exact mechanism is most likely more distributed.
Antworten
-
orbitofrontal
-
ventrolateral
-
dorsolateral
