  1. 1branch of psychology that analyzes how the brain and neurotransmitters influence our behaviors, thoughts and feelings.Biological Psychologists
  2. 2a cell that works to carry messages throughout the bodyneurons
  3. 3nerve cells within the nervous system responsible for converting external stimuli from the organism's environment into internal electrical impulses.Sensory Neurons
  4. 4Neurons in the central nervous system that project their axonsMotor Neurons
  5. 5Neurons within the brain and spinal cord that communicate internally and intervene between the sensory inputs and motor outputsInterneurons
  6. 6neuron that fires both when an animal acts and when the animal observes the same action performed by another. (found in the premotor cortex of humans)Mirror Neurons
  7. 7Contains the nucleus (brain) of the cell. Tells the cell to fire or not to fire.Soma (Cell Body)
  8. 8Wire like structure that extends from the soma to the axon terminal buttons. It is like a highway in which the messages will travel down the neuron.Axon

  36. 36the endocrine system's most influential gland; under the influence of the hypothalamus, the pituitary regulates growth and controls other endocrine glandsPituitary Gland
  37. 37tissue destruction; a brain lesion is a naturally or experimentally caused destruction of the brain tissueLesion
  38. 38an amplified recording of the waves of electrical activity that sweep across the brain's surface; these waves are measured by electrodes placed on the scalp.Electroencephalogram (EEG)
