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






2. Covers whole neuron - selective permeability - sometimes lets ions (positive charge) through






3. PNS - interacts with internal environment - - Responsible for the 'fight or flight' response - - It controls the involuntary functions including movement of smooth muscles - digestion - blood circulation - breathing






4. Controlled by hypothalamus - regulation of hormones in the body - The 'master gland' of the endocrine/hormone system






5. 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






6. Increase effects of a neurotransmitter (e.g. selective serotonin reuptake inhibitors [for depression] increase serotonin activity)






7. Of cerebral cortex - responsible for somatosensory system






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






9. Low-amplitude and fast -frequency alpha waves






10. Of pituitary - stress hormone - increases androgen and cortisol production






11. Provide myelin in central nervous system






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






13. Bundles of axon - Nerve fiber






14. Occur during specific periods in development - permanent or long-lasting effects; - presence of H-Y antigen in development causes fetus to develop into a male - absence to female; - androgens in males and estrogen in females causes secondary sex cha






15. Bumps on the brainstem - controls auditory reflexes






16. Presence during development causes a fetus to develop into a male (absence cause the fetus to develop into a female)






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






18. Incredible rage easily provoked when cerebral cortex is removed






19. Time after a neuron fires which it cannot respond to stimulation






20. Stage 0 & 1 non-REM sleep - low-amplitude and fast-frequency waves






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






22. Connections between brain and spine






23. Of mesencephalon - vision and hearing






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






25. Inner core of spine - cell bodies and dendrites






26. Released from the pituitary and facilitates birth and breast feeding - also involved in pair bonding (mother to child or romantic partners) -






27. 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






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






29. Increase in males during puberty causes genitals to matures and secondary sex characteristics to develop - example: testosterone






30. Decrease effects of a neurotransmitter (e.g. botox is an acetylecholine antagonist that decreases muscle activity)






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






32. Outer covering of spine - nerve fibers - axon bundles - myelin sheathing






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






34. An amino acid - most abundant excitatory neurotransmitter.






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






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






37. Holds neurotransmitters






38. In females - regulate the development of ovum and trigger ovulation - In males - regulate the development of sperm cells and the production of testosterone






39. Dysfunction in certain cortical association area - inability to write






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






41. Fissures seen on cortex surface






42. 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 -->






43. Tough connective tissues that cover/protect brain and spinal cord






44. Of telencephalon - structures around the brainstem involved in 4Fs (fleeing - feeding - fighting - and fornicating)






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






46. Include serotonin - lack of serotonin is linked with depression






47. Of hindbrain - has pons(connects brain parts to spine) and cerebellum(controls muscle coordination - balance - posture)






48. Bumps seen on cortex surface






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






50. Organizational and activational
