Biological Bases
Across
- 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
Down
- 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
