TESTE DEIN WISSEN

How does TMS function as depression treatment?

Lösung anzeigen
TESTE DEIN WISSEN

- rapid rTMS 5Hz-> enhance motor excitability

- slow rTMS 1Hz-> depress excitability 

to left-side dorsolateral prefrontal cortex (positive emotions) 

- newer form of rTMS called intermittenes theta burst stimulation (iTBS)

  • mimics endogenous theta rhythms

- rTMS in depression: train different brain parts to change the excitability of these regions

What is top- down processing?

Lösung anzeigen
TESTE DEIN WISSEN

- when we form our perceptions starting with a larger object, concept, or idea before working our way toward more detailed information

- from general to specific

- Your brain applies what it knows and what it expects to perceive and fills in the blanks

e.g. reading, stroop task (say the color of the word but not the actual word itself)

Relationship between alpha activity and forebrain activity

Lösung anzeigen
TESTE DEIN WISSEN

- high alpha activity: low brain activity

- low alpha activity: high brain activity

What is the stroop task?

Lösung anzeigen
TESTE DEIN WISSEN

- traditional Stroop task involves naming the ink color of colored words

  • ink color congruent (“RED” printed in red ink)
  • sometimes they are incongruent (“RED” printed in blue ink)
  • name the word or the color of the word
  • measure the reaction time how long they need and the accuracy 
  • because automatically read the word, slower to name the color in the incongruent condition-> greater ACC activation is observed

TESTE DEIN WISSEN

What brain parts are active during stroop task?

Lösung anzeigen
TESTE DEIN WISSEN

DLPFC

  • active when name the color (top- down process)
  • more activity, less conflict
  • responsible for maintaining and representing context information
  • most activation in the left DLPFC, smallest stroop interference effect

ACC

  • Greater activity when incongruent
  • consistent with a role in conflict monitoring
  • individuals showed the largest Stroop interference effect tended to have more ACC activation
  • ACC activity increases when top-down control is low

Which brain areas are involved in emotion?

Lösung anzeigen
TESTE DEIN WISSEN

- Left hemisphere (left PFC)

  • positive stimuli
  • active by more aggression

- Right hemisphere (right PFC)

  • negative stimuli
  • more active when less aggressive

- limbic system (amygdala, hippocampus...)

TESTE DEIN WISSEN

Phineas gage- which brain parts impaired results in what symptoms?

Lösung anzeigen
TESTE DEIN WISSEN

- limited to the left frontal lobe

- problems with emotional processing and rational decision-making (future plan making impaired)

- no long term goals

- stimuli driven (monkey experiment)

TESTE DEIN WISSEN

What is approach motivated behavior and which brain part is active?

Lösung anzeigen
TESTE DEIN WISSEN

- achieving positive outcomes related to left-hemispheric brain activation, translate to a variety of right-oriented behavioral biases

- aggression more approach

- positive emotions-> approach

TESTE DEIN WISSEN

Avoidance/ withdrawal behavior& brain parts?

Lösung anzeigen
TESTE DEIN WISSEN

- withdrawal motivation-> right- hemispheric activation

- negative emotions-> avoidance

TESTE DEIN WISSEN

How does brain activity influence fair behavior and decision making?

Lösung anzeigen
TESTE DEIN WISSEN

- fair offer: associated with activity in ventral stratium (reward processing)

- unfair offer: negative emotions, activation of anterior insula 

- DLPFC (cognitive control also for emotions, overriding prepotent emotional biases)

- emotional processes driven by subcortical, limbic& paralimbic structures

- deliberate processes driven by anterior, dorsolateral prefrontal cortex& posterior parietal regions 

anterior insula (processing of emotions) 

- DLPFC

  • controls impulse unfair offers to reject
  • cognitive control of the emotional impulse associated with fairness goals
  • executive control, goal maintenance, inhibition of prepotent responses 
  • key role in overriding or weakening self-interested impulses
  • implementation of fairness motives
  • causal evidence functional role of the right DLPFC not only in overriding immediate selfish impulses also acting strategically fair

How does the Ultimatum game works?

Lösung anzeigen
TESTE DEIN WISSEN

- dictator more interesting to observe

- examine strategic thinking in bargaining, reciprocal fairness

- tension between economic self-interest- reciprocity and equity motives

  1. Proposer can allocate the money
  2. Proposer and responder agree on a division of an amount of money
  3. Responder can accept or reject the offer
  4. Economic self-interest alone motivates the responder-> accept even very low offer
  5. Reciprocity and equity motivate him-> reject low offers (view them as insultingly unfair)

TESTE DEIN WISSEN

What is bottom- up processing?

Lösung anzeigen
TESTE DEIN WISSEN

- ACC more active

- processing sensory information as it is coming in

- built up from the smallest pieces of sensory information

  • Focuses on incoming sensory data
  • More data driven
