behavior in the context of organs
Behavior in the contextof organs
  • Organs are parts of organism …
  • Organs have specialized functions for survival of organism…
  • Organs include, most importantly, the human brain
behavior in the context of organs4
Behavior in the contextof organs
  • Main area of research at organ level is the BRAIN
  • The brain is the organ of human behavior …
  • The brain, interacting with environmental influences, determines how we behave…
behavior in the context of organs5
Behavior in the contextof organs
  • All environmental influences must be received via the senses, perceived, and processed by the brain before a person can behave.
  • Everything we smell, see, hear, taste, or touch is experienced in our brains.
  • No behavior occurs without sensory information being relayed to the brain.
main brain functions
Main Brain Functions
  • There are FIVE MAIN brain functions:
  • Sensation
  • Motion / Movement
  • Reproduction / Internal Regulation
  • Emotion
  • Thought / Cognition
  • Most important for crime?
brain structure and process
Brain Structure and Process
  • Brain can be divided into:

brain structure and process11
Brain Structure and Process
  • Brain can be divided into:
  • Cortex and Subcortex
brain structure and process13
Brain Structure and Process
  • Cerebrum -- largest portion of cortex -- wrinkled mass in 2 hemispheres
  • Divided into FOUR LOBES
  • http://en.wikipedia.org/wiki/Cerebral_cortex
brain structure and process14
Brain Structure and Process
  • Frontal lobe – thought, intellect, associations, planning, intent, inhibition/self control
  • Parietal lobe – works with frontal lobe, movement, sensation
  • Occipital lobe – vision, abstract concepts
  • Temporal lobe – hearing, learning/memory, autonomic response, regulation of hormones, emotion, aggression

  • The parts most important for criminal behavior are frontal lobes and temporal lobes
  • Thus, overactive temporal lobe or underactive frontal lobe can result in “bad” behavior …
