Biological Bases

4. device that monitors and records waves of electric activity within the brain
5. technique for revealing bloodflow and, therefore, brain activity by comparing successive MRI scans
7. structure of the hindbrain that coordinates voluntary muscular movements
8. neurons that carry information from the receptors to the spinal cord and brain
9. automatic behavior in response to a specific stimulus
11. subcortical structure that relays incoming sensory information to the cerebral cortex
12. chemical messengers that cross the synaptic gap between neurons
15. the oldest part and central core of the brain
16. a molecule (e.g., drug) that enhances the operation of a neurotransmitter
17. cell body of a neuron
18. structure in the limbic system important in processing memories
21. wide band of neural fibers that connects the two hemispheres of the brain

1. the sensory and motor neurons that connect the CNS to the rest of the body
2. neurons that carry information from the brain and spinal cord to the muscles
3. band of nerve fibers that run through the center of the brain stem
6. division of the peripheral nervous system that control's the body's skeletal muscles.
7. Division of the nervous system that consists of the brain and spinal cord
10. a nerve cell; basic cell of the nervous system
13. base of the brainstem; controls heartbeat & breathing
14. a group of structures located beneath the cerebral cortex that are involved in regulating emotions
19. structure of the brainstem that allows for communication between the cerebellum
20. site where two or more neurons interact but do not touch
