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






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






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






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






5. Bumps on the brainstem - controls auditory reflexes






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






7. Connections between brain and spine






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






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






10. Provide myelin in peripheral nervous system






11. Gray matter - white matter






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






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






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






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






16. PNS - interacts with external environment by controlling voluntary movements of striated muscles






17. Divided into diencephalon and telencephalon






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






19. Organizational and activational






20. Of cerebral cortex - responsible for somatosensory system






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






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






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






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






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






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






27. Between myelin sheath - help send impulse down axon






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






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






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






31. End of a neuron (terminal buttons)






32. PNS fibers that run towards CNS






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






34. An amino acid - most abundant inhibitory neurotransmitter






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






36. 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






37. Of diencephalon - channels sensory information to cerebral cortex






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






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






40. 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






41. Base in hindbrain - rest in midbrain; oldest brain area; Controls alertness - thirst - sleep - involuntary muscles (i.e. heart)






42. Where soma and axon connect






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






44. 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






45. 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)


46. 16 hours of sleep a day - 6 hours






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






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. Dysfunction in certain cortical association area - difficulty processing sensory information






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