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






2. Measures oxygen flow in different brain areas - used most in cognitive psych to measure activity in different brain regions during certain tasks






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






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






5. An amino acid - most abundant inhibitory neurotransmitter






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






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






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






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






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






11. PNS fibers that run towards CNS






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






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






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. Dysfunction in certain cortical association area - language disorder from damage to Broca'S area - in left frontal lobe; can understand speech but has difficulty speaking (slow - laborious - omits words)

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






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






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






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






20. Contain synaptic vessels that hold neurotransmitters






21. Dysfunction in certain cortical association area - language disorder from damage to Wernicke'S area - in left temporal lobe; can speak but doesn'T understand how to correctly choose words (fluent but nonsensical)

22. Of cerebral cortex - responsible for vision






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






24. Fissures seen on cortex surface






25. Pathway that runs to and from CNS






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






27. Provide myelin in central nervous system






28. Divided into diencephalon and telencephalon






29. Bumps on the brainstem - controls auditory reflexes






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






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






32. Fast frequency bursts of brain activity - inhibits processing to keep tranquil state






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






34. Made up of brain and spinal cord






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






36. Control large voluntary muscle movements - Their degeneration is related to motor dysfunction in Parkinson'S and Huntington'S






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






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






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






40. Low-amplitude and fast -frequency alpha waves






41. 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






42. (1) resting potential - neuron negatively charged - cell membrane does not let ions in; (2) presynaptic cell releases neurotransmitters from terminal buttons; (3) postsynaptic receptors in postsynaptic cells detects neurotransmitter and open ion chan






43. Made of thalamus and hypothalamus






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






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






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






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






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






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






50. Provide myelin in peripheral nervous system
