Across
- 2. a branch-like extension of the neuron that receives input and communicates with other neurons
- 6. transmits signals between different parts of the body, coordinates actions, and provides the biological basis for psychological experiene
- 7. clusters of neurons found under the forebrain, and a key area for selecting action, learning and motor control
- 8. serves basic life functions (such as heart rate) and connects the CNS to internal organs that or involuntarily or automatically regulated by the brain
- 10. the outer layer (2-5mm thick) of the forebrain that is key area for higher order functions
- 11. a biological cyclical occurance that operates more than once a day. eg; the sleep cycle
- 15. a device that Detects, Amplifies, Records the Electrical activity of the muscles responsible for controlling eye movement
- 16. a part of the PNS, conveying sensory info to the CNS and motor messages to the muscles
- 20. division of the autonomic NS that dominates when under stress by activating internal muscles to initiate a 'fight or flight' response
- 22. based on personal experience or feeling, not from external evidence
- 25. average 6-7 hours of sleep a night, and experience less deep slow-wave sleep, and may not go through stage 3 or 4 at all
- 27. nerve cells found entirely within the CNS that act as a link between sensory neurons and motor neurons
- 28. 16-17 hours a day of sleep, and sleep and wake about 4-5 times a day. spend 90% of sleep in REM
- 29. data that is free of bias and is unable to be changed or manipulated
- 31. the connection, including the gap between neurons, across which signals are carried by neurotransmitters
- 32. a stage of sleep characterised by quick, jerking eye movements, increased heart rate, blood pressure and metabolic rate, and a complete paralysis of the muscles in the body. REM sleep is also called 'paradoxical sleep'
- 33. not sleeping at all
- 34. largest part of the hindbrain involved mostly in the coordination of movement
- 35. a layer of insulation around the axon
Down
- 1. at 3-5 years of age, 10-12 hours of sleep a day. 20-25% of sleep is REM. by 10yo, they sleep 8-10 hours a day
- 3. a neuron conducting impulses outwards from the brain or spinal cord
- 4. division of the autonomic NS that dominates in calm and maintains the sense of homeostasis in normal functioning
- 5. a sleep study consisting of many measures to assess the functions of the body and brain during sleep
- 9. a device that Detects, Amplifies, Records the Electrical activity of the neurons inn the brain
- 12. consists of four stages of sleep characterised by little to no eye movements, decreased heart rate, blood pressure and metabolic rate, and a relaxation of the body's muscles where movement is possible
- 13. carries information between the CNS and the rest of the body
- 14. require 8 hours of sleep a night, of which REM occupies 20% of
- 17. the nerve fibre of a neuron
- 18. the brain and spinal cord- the control, decision making and communication centre, also responsible for reflexes
- 19. a personal account or a personal interpretation of data which may contain unintentional bias and/or inaccuracies
- 21. an automatic response made by a pathway of neurons from sense organs to the spinal cord to the muscles without going to the brain
- 23. a neuron conducting impulses inwards to the brain or spinal cord
- 24. sleeping for some of the night, but not getting enough sleep as required
- 26. a biological ocurrance that operates once a day, eg; the sleep-wake cycle
- 30. steady state of balanced normal functioning
