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. Holds neurotransmitters






2. 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






3. Increase in female during puberty causes genitals to matures and secondary sex characteristics to develop






4. Bumps on the brainstem - controls visual reflexes






5. Comprise two classes of neurotransmitters - indolamines and catecholamines






6. Positron emission tomography - scans glucose metabolism to measure activity in various brain regions






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






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






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






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






11. Of pituitary - activates thyroid






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






13. PNS fibers that run towards CNS






14. Bumps on the brainstem - controls auditory reflexes






15. Of diencephalon - channels sensory information to cerebral cortex






16. Of cerebral cortex - responsible for somatosensory system






17. Organizational and activational






18. Of cerebral cortex - responsible for hearing - also Wernicke'S area (related to speech)






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






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






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






22. Inner core of spine - cell bodies and dendrites






23. Stage 3 (less sleep spindles) & 4 non-REM sleep - high-amplitude and low-frequency - deepest level of sleep






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






25. Provide myelin in peripheral nervous system






26. Connections between brain and spine






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






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






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






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






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






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






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






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






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






36. 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






37. Of telencephalon - links brain areas dealing with emotion and decisions






38. Beginning of neuron (dendrites)






39. Made up of brain and spinal cord






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






41. Made of thalamus and hypothalamus






42. Contain synaptic vessels that hold neurotransmitters






43. Bumps seen on cortex surface






44. Chambers filled with cerebrospinal fluid that insulate brain from shock






45. Fissures seen on cortex surface






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






47. Present in fast-acting - directed synapses






48. (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






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






50. Low-amplitude and fast -frequency alpha waves
