Q

thalamic and habenular nuclei

A

thalamic nuclei integrate and gate information flow to cortex

habenular nuclei play a role in control of emotional and social behaviors relative to pain, stress, and anxiety, and play a role in sleep

Q

dorsolateral prefrontal cortex (dlPFC)

A

involved in goal representation and attentional control

helps resist temptation in order to meet long term goals (self control)

stores emotional memories used in decision making

Q

venteromedial prefrontal cortex (vmPFC)

A

assigns value to emotional inputs during decision making

plays a role in risk assessment, decision making, social judgements, and self control

Q

orbitofrontal cortex (OFC)

A

processes information about rewards from the environment

involved in developing preferences and choosing between options

inhibits inappropriate actions (delay of gratification)

16
Q

posterior insula

A

monitors interoceptive information from the viscera and can send this information to the anterior insula; creates a body-based “feeling state”

16
Q

anterior cingulate cortex (ACC)

A

detects conflict during problem solving and in new situations

helps to prioritize attention, make choices, and predict consequences

uses information from cortex & limbic areas to inform decision making and action selection

helps calculate cost-benefit analysis (is the effort worth the reward)

17
Q

anterior insula

A

constructs a representation of how one feels

integrates information from the posterior insula with contextual information (environment, task, people) to make emotional judgements (trust, anxiety, empathy)

creates a global “feeling state” that guides decision making

18
Q

amygdala

A

receives sensory information from the thalamus and sends emotional information to cortical areas

creates emotional associations with stimuli in the environment

19
Q

hypothalamus

A

regulates biological functions and responds to natural rewards (food)

regulates the endocrine system (pituitary gland) and the ANS

produces visceral responses to emotions

20
Q

ventral striatum (nucleus accumbens)

A

pleasure center of the brain

activated by things we like, want, value, prefer, and enjoy

receives dopaminergic input from the VTA - mesolimbic pathway

21
Q

ventral palladium (substantia innominate)

A

receives input form the ventral striatum and other rewards-related areas

translates reward related motivation signals from the limbic system into motor output

22
Q

mesocorticolimbic pathway

A

mesolimbic projections: VTA –> nucleus accumbens, amygdala, hippocampus (dopamine pathway appraises the amount of reward a stimulus provides)

mesocortical projections: VTA –> PFC (orbitofrontal cortex) (dopamine pathway brings awareness to stimuli that produced past rewards and promotes goal directed behaviors to seek out rewarding stimuli)

23
Q

orbitofrontal-striatal circut

A

circuit between PFC (orbitofrontal cortex and dorsolateral PFC) and the ventral striatum (nucleus accumbens)

helps with choice of large delayed reward over small immediate reward

delayed gratification

24
Q

ventromedial prefrontal - amygdala pathway

A

important for value-based decision making and rewards processing

vmPFC can suppress fear responses from the amygdala

pathway implicated in PTSD

receiving feedback about failure may decrease vmPFC activation; however, making choices based on one’s preferences during a task can help maintain vm PFC activation even when receiving failure feedback, leading to improved performance

25
Q

anterior insula - anterior cingulate cortex circuit

A

awareness of emotions (anterior insula) is used to make decisions about actions based on anticipated consequences (anterior cingulate cortex)

26
Q

Volition

A

mental control over an action/ongoing effort to sustain motivated action

ANTERIOR CINGULATE CORTEX is involved in exerting mental control and problem solving

premotor and supplementary motor areas are activated in preparation for volitional actions

27
Q

self regulation/goals

A

prefrontal cortex generates goals and intentions

DORSOLATERAL PFC is involved in pursuing long term goals

ANTERIOR CINGULATE CORTEX involved in monitoring conflict, integrating emotions, and making decisions about changing course of action

28
Q

extrinsic motivation (incentive motivation)

A

engaging in behavior bc it leads to some separate consequences like gaining a reward

ORBITOFRONTAL STRIATAL CIRCUIT and ANTERIOR CINGULATE CORTEX helps determine if the reward is worth the effort

providing extrinsic rewards can decrease intrinsic motivation

29
Q

intrinsic motivation

A

doing a behavior bc activity itself is interesting and spontaneously satisfying

ANTERIOR INSULA is activated by intrinsic rewards

30
Q

basic psychosocial needs (supports intrinsic motivation)

A

competence, autonomy, relatedness

ANTERIOR INSULA and rewards system are involved

31
Q

autonomous self-regulation

A

volition decision making that are based on one’s sense of autonomy

activates VENTROMEDIAL PFC

can help resolve conflicts in the anterior cingulate cortex
