Brain structure and aggression

Cards (58)

  • What are the assumptions of the biological approach?
    Behavior explained by brain structures, neurotransmitters, evolution
  • How many lobes does the brain have?
    Four lobes
  • What does the frontal lobe control?
    plays an important part in decision making and self-restraint
  • How can you remember the parietal lobe's function?
    Parents raised you, so they are at the top
  • What does the occipital lobe control?
    Vision, color identification, visual processing
  • How can you remember the temporal lobe's function?
    Temperature is taken in the ear at the doctor
  • What is the corpus callosum's function?
    Links the two hemispheres of the brain
  • What happens if the corpus callosum is split?
    Messages can't be sent across hemispheres
  • What are lesions in the context of brain research?
    Purposeful damage or stimulation of brain areas
  • Which part of the brain is linked to aggressive behavior?
    The hypothalamus
  • What is the role of the prefrontal cortex?
    Linked to emotions and decision-making
  • What did Raine's study find about the prefrontal cortex?
    Lower function linked to less consequence thinking
  • What did Bicara's study reveal about the prefrontal cortex?
    Damage leads to focus on immediate rewards
  • What is the limbic system composed of?
    Hippocampus, amygdala, hypothalamus
  • What role does the amygdala play in aggression?
    Stimulated amygdala increases aggression levels
  • What happens to animals without an amygdala?
    They become passive and unresponsive
  • What is the amygdala's role in emotional response?
    Integrates stimuli causing reactions to environment
  • What is the fight or flight response associated with?
    The limbic system and amygdala
  • How does the prefrontal cortex relate to aggression?
    Regulates emotions; damage leads to aggression
  • What is the significance of Phineas Gage's case?
    Injury led to aggression, linking brain structure to personality
  • What is tray panning?
    Surgical intervention to treat brain problems
  • What does bilateral refer to?
    Two sides
  • What does unilateral refer to?
    One side
  • What is the role of the hippocampus?
    Converts short-term to long-term memories
  • What does the hypothalamus regulate?
    Temperature, hunger, thirst, pain responses
  • How does the hypothalamus relate to aggression?
    Links to offensive and defensive behavior
  • What is the significance of the medial hypothalamus?
    Linked to offensive behavior and physical attack
  • What is the role of the amygdala in fear response?
    Stimulated amygdala causes aggressive response
  • What happens when the amygdala is removed?
    Animal becomes passive and unresponsive
  • How does the limbic system contribute to aggression?
    Controls temperature, survival, and fight or flight
  • What is the relationship between dopamine, serotonin, and aggression?
    Prefrontal cortex connects to these neurotransmitters
  • What is the impact of lower prefrontal cortex activity?
    Leads to less regulation of behavior
  • What is the significance of the classic study by Raine?
    Links low prefrontal cortex activity to aggression
  • How does aggression manifest in lab animals with hypothalamus damage?
    Increased aggressive behavior when stimulated
  • What is the role of the prefrontal cortex in planning?
    Regulates long-term planning and consequences
  • What is the relationship between aggression and the limbic system?
    Limbic system controls emotional responses, including aggression
  • How does the amygdala respond to stimuli?
    Integrates stimuli causing aggressive reactions
  • What is the effect of stimulating the amygdala?
    Causes aggressive responses in animals
  • What is the significance of the hypothalamus in aggression?
    Regulates aggressive behavior and responses to threats
  • How does the prefrontal cortex affect emotional regulation?
    Damage leads to uncontrolled aggressive reactions
