Exam 3 Week 16 ppt 4: Cognition Prefrontal Cortex Flashcards
what does the prefrontal cortex have rich connections with? (5)
The pre-frontal cortex has rich interconnections with
- hypothalamus,
- amygdala,
- basal forebrain,
- midbrain &
- hippocampus
orbital frontal cortex represents what?
Orbital frontal cortex represents the
–Highest regulation of autonomic function & social-emotional behavior
what are three things the orbitofrontal cortex is involved in?
It is involved in
- impulse control,
- socially acceptable behaviros and
- planning
what does damage to the orbitofrontal cortex cause? (5)
–Damage produces
- irresponsible,
- impulsive behaviors,
- lack of planning,
- focus &
- organizational skills
what is hyperactivity of the orbitofrontal cortex associated with?
Hyperactivity Orbitofrontal cortex is associated with obsessive-compulsive disorder
whtat is the dorsolateral frontal cortex involved in? (4)
Dorsolateral frontal cortex is Involved in
- analytical thinking,
- problem solving,
- keeping focus & attention, and
- planning
what does damage to the dorsolateral frontal cortex result in? (4)
–Damage results in
- disordered thinking and
- disorganized behavior with an
- inability to maintain focus and
- being easily distracted
What is the ventromedial frontal cortex involved in? (3)
The Ventromedial frontal cortex is Involved in
- motivation,
- gaining emotional pleasure from life experiences and
- connecting emotions and thoughts
what does damage to the ventromedial frontal cortex cause? (4)
Damage to the Ventromedial frontal cortex produces
- apathy,
- anhedonia,
- flat emotional affect,
- inability to report preferences,
in what condition is the ventromedial frontal cortex hyperactive?
mania
in what condition is the ventromedial frontal cortex less active?
clinical depression
what are two settings that the prefrontal cortex has a role in regulating?
- –Private element
- –Public forum
what does the public forum require? (3)
•Public Forum
- –Interaction with others
- –Requires accurate perception of others emotional states
- –Capacity to deal with others mental states
how does the prefrontal cortex help deal with others in the public forum?
when dealing with others in the Public Forum,
- Sensory awareness funneled thru amygdala and
- Integrated into your behavior in orbital prefrontal cortex
what does the private elemenet of behavior require?
Private element of behavior requires Social reasoning which is the matching internal state with social action
Examples of Private element’s Social reasoning include Empathy & altruism.
what re two examples of the private element’s social reasoning?
Examples of Private element’s Social reasoning include Empathy & altruism.
what does damage to the orbitofrontal cortex lead to in regards to the private elelment? (3)
•Damage to orbitofrontal cortex leads to
- selfish, egocentric behaviors,
- lack of empathy &
- engage in thoughtless acts
Who is Robin Dunbar, and what did he suggest?
- •Robin Dunbar, evolutionary psychologist, has suggest-ed that the development of these areas is responsible for the “great leap forward” by humans 40-60,000 years ago
- •Socialization ability drove human development & these areas (the prefrontal cortex) responsible
what is the significance of Phinneas Gage?
- •Perhaps the first documented insight to the role of the frontal lobes in emotional experience and behavior
- •Iron rod passed through Gage’s prefrontal lobe and skull
- •Forever changed his personality to be irreverent, profane, impatient, and obstinate
