Neocortical Control System Flashcards
What controls the autonomic (visceral) nervous system (ANS)?
Hypothalamus
Describe the function of the ANS
The ANS regulates bodily functions in response to the instinctive or visceral needs of the organism
ARAS neurotransmitters?
The ascending reticular activating system (ARAS) mainly uses acetylcholine (ACh), some gamma amino-butyric acid (GABA) and histamine (HA) as its major neurotransmitters
TMMS neurotransmitters?
The trimonoamine modulating system (TMMS), relies on dopamine (DA), noradrenaline (NA) and serotonin (5-HT)
mesocortical pathway major function?
The mesocortical “reward” pathways are involved in the anticipation or expectation of future reward
THINKING
mesostriatal pathways major function?
The mesostriatal “reward” pathways are involved in the
“default” or “motor” response to immediate needs
DOING
mesolimbic pathways major function?
The mesolimbic “reward” pathways are involved in
immediate gratification
FEELING
Central Executive Network location?
Frontoparietal system
CEN function?
Working memory and attention. The CEN nodes appear to be strongly activated during tasks that require integration and higher order thought and reasoning
Network responsible for actively maintaining and manipulating information in working memory
CEN
Network responsible for decision making in the context of goal directed behaviour
CEN
Network responsible for rule-based problem solving
CEN
DMN major node location?
The DMN has prominent nodes in the medial temporal lobe (MTL) and the angular gyrus
Name the two subcortical areas of the Salience Network
The amygdala amd The substantia nigra (SuN)/ventral tegmental area (VTA)
Key role SN?
To work out which are the most important stimuli
needing our attention at any given time.
