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






2. An amino acid - most abundant excitatory neurotransmitter.






3. Where soma and axon connect






4. Present in fast-acting - directed synapses






5. Holds neurotransmitters






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






7. Contain synaptic vessels that hold neurotransmitters






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






9. Chemicals that stimulate nearby cells






10. 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






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






12. Divided into diencephalon and telencephalon






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






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






15. Of cerebral cortex - responsible for somatosensory system






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






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






18. Of mesencephalon - vision and hearing






19. Of pituitary - activates thyroid






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






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






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






23. Organizational and activational






24. Bumps on the brainstem - controls visual reflexes






25. (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






26. Linked to pleasure and analgesia; can be endogenous (opioid peptides) or exogenous (morphine or heroin) - Exogenous endorphine are highly addictive






27. 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






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






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






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






31. Consists of myelencephalon - metencephalon - and reticular formation






32. Inner core of spine - cell bodies and dendrites






33. Bumps seen on cortex surface






34. Takes about half an hour; (0) prelude to sleep - neural synchrony; alpha waves; person is relaxed and drowsy - closes eye; (1) Eyes begin to roll. alpha waves give way to irregular theta waves; loses responsiveness to stimuli - experiences fleeting t






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






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






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






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






39. Pathway that runs to and from CNS






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






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






42. PNS fibers that run towards CNS






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






44. Comprise two classes of neurotransmitters - indolamines and catecholamines






45. 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






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






47. Low-amplitude and fast -frequency alpha waves






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






49. Made up of brain and spinal cord






50. 16 hours of sleep a day - 6 hours
