Psychotherapy: 97b - Behavioral Neuroanatomy
This flashcard set highlights how specific brain regions and network functions relate to mood, motivation, and personality. State networks are responsible for regulating mood and motivation through widespread cortical and neurotransmitter interactions. Connector regions (hubs linking brain modules) are especially vulnerable—lesions here can cause significant cognitive disruption. Finally, damage to the prefrontal cortex can lead to profound changes in personality and judgment, even when other cognitive functions remain intact.
Mood and motivation are attributed to [state/channel] network functions
Mood and motivation are attributed to state network functions
Many different cortical areas play a role; deficits are usually attributed to interference with neurotransmitter pathways
