- - - - frontal lobe
      - parietal lobe
      - occipital lobe
      - temporal lobe
    - - MRI
        
        magnetic resonance imaging
        
        can inform on the structure. The pictures are compiled using the measurement of radio frequency.
      - fMRI
        
        functional magnetic resonance imaging
        
        detects differences in magnetization between poor or rich oxygenated blood flow
      - EEG
        
        electroencephalography
        
        measures brain activity, using electrodes attached to the scalp
      - CAT
        
        computerized axial tomography
        
        gives a still picture of the brain, using X-rays
      - PET
        
        positron emission tomography
        
        gives a moving picture of brain activity. This is achieved by tracking radiation levels in the brain

    - - right hemisphere
        
        recognizing emotion and faces, together with spacial functioning
      - left hemisphere

    - - an androgen (a male hormone). implicated in behavior such as aggression
    - - fight or flight
  - - - testosterone levels
    - - twin studies
    - - may increase the chances of survival
  - - - the way the signal is transmitted down the neuron to the next synapse
    - - the way the brain can transmit activation. There are billions of neurons in the human brain
    - - the small fluid-filled gap between neurons which is essential for transmission of the nerve signals
    - - the process of signal from neuron to neuron
    - - the ability of the nervous system, especially the brain, to adapt to the environment and to replace function following damage
    - - biochemicals found within the brain that play an important part in transmitting messages from neuron to neuron
    - - the genetic constitution of an individual organism
    - - the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment
    - - the presence of the same trait in both members of a pair of twins
  - - - replacement
      - refinement
      - reduction
    - - the term used when findings of animal research are used to help explain human behavior
