Across
- 3. More active when you fall asleep
- 8. Small voltage fluctuations across the cell membrane
- 10. A positive ion that can move freely across the membrane
- 13. Type of seizure that is limited to a specific area
- 14. These appear during stage 2 of sleep
- 15. A structure in the brainstem that is important for autonomic and homeostatic functions
- 17. GABA is used by this area to inhibit the pallidum
- 18. Functions as a gateway for all sensory information to the cortex
- 19. Affected by exposure to enriched environments in rats
- 21. Type of gated channel that opens in response to the membrane reaching a threshold
- 23. The “master” clock
Down
- 1. The thalamus uses this neurotransmitter to excite the cortex
- 2. An increase in the electrical charge across a membrane
- 4. A decrease in this neurotransmitter could cause a seizure focus
- 5. A positive ion that cannot move freely across the membrane
- 6. Decrease in responding with repeated stimulation
- 7. A decrease in the electrical charge across a membrane
- 9. An oxygen with an unpaired electron
- 11. These waves appear during stage 4 of sleep
- 12. The source of norepinephrine
- 16. The colliculus responsible for visual startle reflex
- 20. Developmental window during which events influence brain development
- 22. Measures activity from pyramidal cells in the cortex
- 24. A structure important for muscle coordination, balance and movement
