brain structures

• What are the three brain structures involved in aggression?

  Amygdala, hypothalamus, prefrontal cortex
• What is the primary role of the limbic system?

  Emotional and behavioral responses
• Which two structures make up the limbic system?

  Hippocampus and amygdala
• What is the function of the prefrontal cortex?

  It is in charge of memory
• What problems arise from damage to the prefrontal cortex?

  Short term memory issues and lack of empathy
• What are the functions of the hypothalamus?

  Regulates temperature, hunger, thirst, mood, sex drive, and sleep
• What happens if the hypothalamus is damaged?

  Body features will be deregulated
• What is the primary function of the amygdala?

  In charge of aggression
• What are the effects of damage to the amygdala?

  Irregular behavioral patterns
• What is the frontal lobe known as?

  The control panel of our personality
• What functions does the frontal lobe control?

  Emotional expression, impulse control, judgment, problem solving
• What does the temporal lobe process?

  Memories
• What is the role of the temporal lobe in perception?

  Involved in auditory perception
• What is the primary function of the occipital lobe?

  Processing visual information
• What type of sensory information does the parietal lobe process?

  Tactile sensory information
• What specific types of tactile sensory information does the parietal lobe process?

  Pressure, touch, pain
• What are the main functions of the four lobes of the brain?

  • Frontal lobe: Personality control, emotional expression, impulse control, judgment, problem solving
  • Temporal lobe: Memory processing, auditory perception
  • Occipital lobe: Visual information processing
  • Parietal lobe: Tactile sensory information (pressure, touch, pain)
• Who is Charles Whitman in relation to aggression studies?

  A case study showing amygdala's role
• What does Charles Whitman's tumor near the amygdala suggest?

  It may explain his violent behavior
• What did Bard's 1940 study demonstrate about the amygdala?

  Lesions in the amygdala produce aggression
• What happens when the amygdala is stimulated with electric current?

  The animal displays aggressive behavior
• What occurs when the amygdala is removed from an animal?

  The animal becomes passive and unresponsive
• What did Flynn et al. 1970 find regarding the hypothalamus in cats?

  Electrical stimulation produces aggressive responses
• What types of aggressive responses are produced by hypothalamus stimulation?

  Responses include hissing and growling
• How does stimulation of different parts of the brain affect aggression?

  It leads to different types of aggression
• What is a strength of brain structures in aggression theory?

  Case studies link aggression to the amygdala
• How do case studies like Charles Whitman contribute to aggression theory?

  They provide evidence linking aggression to the amygdala
• What animal studies are mentioned in relation to aggression?

  Bard and Flynn studies from 1970-1940
• From which brain structures does aggression arise according to the theory?

  Aggression arises from the limbic system
• Which specific brain structures are involved in aggression?

  Amygdala and hypothalamus
• What type of evidence supports the theory of aggression?

  Brain scans provide supporting evidence
• What is a limitation of generalizing findings from brain studies on aggression?

  Not all aggressive individuals have amygdala tumors
• Why is it difficult to generalize animal studies to humans in aggression research?

  Animal studies may not reflect human behavior
• What do brain scans identify in relation to aggression?

  They identify socialization, not causation
• What does the evidence from brain scans imply about aggression?

  It suggests correlation, not direct causation
• What can PET scans inform decisions about?

  Appropriate sentencing and parole
• How might changes in aggression levels be useful?

  They may indicate demand or damage
• What is a potential benefit of PET scans in diagnosis?

  Helpful in diagnosing specific conditions
• What are the strengths and shortcomings of scientific techniques like PET and MRI scans?

  Strengths:

  • Scientific credibility

  
  

  Shortcomings:

  • Deterministic nature
  • Suggests lack of agency in decisions
• What does the deterministic nature of PET and MRI scans imply?

  Some people are inherently aggressive
