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






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






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






4. Dysfunction in certain cortical association area - inability to organize movement






5. Released at neuromuscular junction to cause contraction of skeletal muscles - also involved in parasympathetic nervous system






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






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






8. End of a neuron (terminal buttons)






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






10. Overeating with no satiation of hunger; leads to obesity; damage to ventromedial region of hypothalamus






11. An amino acid - most abundant inhibitory neurotransmitter






12. Between myelin sheath - help send impulse down axon






13. Bumps seen on cortex surface






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






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






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






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






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






19. Consists of limbic system - hippocampus - amygdala - cingulate gyrus






20. Of pituitary - regulate water levels in body and therefore BP






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






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






23. Outer half-inch of cerebral hemispheres; - sensory and intellectual functions; - split into frontal - occipital - parietal - temporal lobes; - 90% is neocortex (new in evolution - 6 layers cortex) - 10% < 6 layers and more primitive






24. Inner core of spine - cell bodies and dendrites






25. Low-amplitude and fast -frequency alpha waves






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






27. Neuron branches - receive impulses - branching patterns change throughout life






28. Fatty - insulating sheath on some axons for faster conduction of axon impulses






29. 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






30. An amino acid - most abundant excitatory neurotransmitter.






31. Provide myelin in peripheral nervous system






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






33. Chemicals that stimulate nearby cells






34. Beginning of neuron (dendrites)






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






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






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






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






39. The basic unit of the nervous system - Consist of: Dentrites - cell body (soma) - axon hillock - axon - myelin sheath - nodes of Ranvier - Terminal buttons - cell membrane - synapse - glial cells






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






41. Gray matter - white matter






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






43. Of Hindbrain - aka medulla; Mainly controls for reflexes - but also controls sleep - attention - movement






44. Extension of the spine - developed from base to the front






45. 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 -->






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






47. Comprise two classes of neurotransmitters - indolamines and catecholamines






48. Bundles of axon - Nerve fiber






49. Dysfunction in certain cortical association area - inability to read






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