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






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






3. 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






4. PNS fibers that run towards CNS






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






6. End of a neuron (terminal buttons)






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






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






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






10. Comprise two classes of neurotransmitters - indolamines and catecholamines






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






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






13. Bumps on the brainstem - controls auditory reflexes






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






15. 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






16. Of cerebral cortex - responsible for somatosensory system






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






18. Of mesencephalon - vision and hearing






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






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






21. Of diencephalon - channels sensory information to cerebral cortex






22. 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 -->






23. 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)

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






25. Organizational and activational






26. Made of thalamus and hypothalamus






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






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






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






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






31. Provide myelin in central nervous system






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






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






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






35. 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






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






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






38. Contain synaptic vessels that hold neurotransmitters






39. Provide myelin in peripheral nervous system






40. Chemicals that stimulate nearby cells






41. Connections between brain and spine






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






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






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






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






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






47. Midbrain; contains tectum and tegmentum






48. Where soma and axon connect






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






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