GRE Psychology: Physiological/behavioral Neuroscience 1

Subjects : gre, psychology
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Inner core of spine - cell bodies and dendrites






2. Incredible rage easily provoked when cerebral cortex is removed






3. Once minimum threshold is met - intensity always the same regardless of amount of stimulation






4. Process in which neural pathways are connected and then some die out (children go through these process)






5. Stage 1 & 2 non-REM sleep (with sleep spindles) - lower-amplitude and slower frequency waves






6. Or just synapse - the space between 2 neurons where they communication






7. Changes in a nerve cell'S charge as the result of stimulation - 2 forms: excitatory postsynaptic potential and inhibitory postsynaptic potential






8. Like neurotransmitters but cause long-term changes in postsynaptic cell






9. Inactivated state of a neuron






10. Made up of brain and spinal cord






11. Of diencephalon - controls autonomic nervous system biological motivations (hunger - thirst) and pituitary gland






12. Depolarization - + from outside allowed into cell - increase firing






13. Of mesencephalon - vision and hearing






14. Aka cell body. largest central portion - and make up gray matter - has a nucleus that directs neuron'S activity






15. Transmits impulses of neuron - bundles of these are nerve fibers (white matter); the wider nerve fiber - the faster its conduction






16. Areas on cortex that correspond to certain functions; - the larger the area - the more sensitive and highly accessed the function - Damage to a particular area would result in certain dysfunction






17. Occurs when people deprived of REM sleep - compensate by spending more time in REM sleep later in the night






18. ANS - recuperation after arousal (decrease HR - BP - respiration)






19. Used to implant electrodes into animals' brains in experiments






20. Of diencephalon - channels sensory information to cerebral cortex






21. For female - the onset of the menstrual cycles - occurs during puberty






22. Of cerebral cortex - responsible for somatosensory system






23. Associated with changes in hormone levels throughout the month - estradiol - progesterone - luteinizing hormone - follicle stimulating hormone






24. Protects the brain by making it difficult for toxic substances to pass from the blood into the brain - since blood vessel cells in the brain are tightly packed






25. Of telencephalon - involves in memory- transfer STM into LTM - - new neurons can form in adult mammalian brain






26. Consists of myelencephalon - metencephalon - and reticular formation






27. Made up of sympathetic nervous system and parasympathetic nervous system






28. Provide myelin in peripheral nervous system






29. Time after absolute refractory period - neuron can fire but needs a much stronger stimulus






30. Hyperpolarization - + let out - - compared to outside - decrease firing






31. Of cerebral cortex - controls speech (Broca'S area) - reasoning - problem solving






32. Include dopamine - lack of dopamine linked with Parkinson'S - excess dopamine is linked with schizophrenia - dopamine is also involved in feelings of reward and therefore addiction






33. Low-amplitude and fast -frequency alpha waves






34. Bumps seen on cortex surface






35. Anytime during adulthood - short periods - often transient or reversible (current/recent circulation); - menstrual cycle (estradiol - progesterone - luteinizing hormone (LH) - follicle stimulating hormone (FSH)); - LH and FSH in females regulate ovum






36. The process after a neurotransmitter has done its job - it is reabsorbed by the presynaptic cell






37. REM-sleep - low-amplitude and fast-frequency waves that characterize waking states






38. Where soma and axon connect






39. Of telencephalon - controls emotional reactions such as fear and anger






40. Jumping from one node of Ranvier to the next due to insulation by myelin sheath






41. Of mesencephalon - rest of reticular formation; Also involved in the sensorimotor system - analgesic effect of opiates






42. Measures brain wave patterns and have made it possible to study waking and sleeping states






43. Made up of somatic nervous system and autonomic nervous system






44. PNS fibers that run away from CNS (to cause effect the brain wants)






45. Comprise two classes of neurotransmitters - indolamines and catecholamines






46. Of pituitary - activates thyroid






47. comprises 50% of total sleep at birth - decreases to 25% - 20% sleep time spent in this type of sleep - Interspersed with non-REM every 30-40min - where dreams are experience - characterized by neural desynchrony - also known as paradoxical sleep -->






48. A type of cell that help support neurons; oligodendrocytes and Schwann cells






49. 16 hours of sleep a day - 6 hours






50. Divided into diencephalon and telencephalon
