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. Bumps on the brainstem - controls auditory reflexes






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






3. Present in fast-acting - directed synapses






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






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






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






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






8. 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 -->






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






10. Between myelin sheath - help send impulse down axon






11. Where soma and axon connect






12. 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)

13. ANS - controls arousal mechanisms (blood circulation - pupil dilation - threat and fear response) - Lie detector test relies on the premise -->lying activates the sympathetic nervous system and cause things like (increase heart rate - blood pressure






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






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






16. Consists of myelencephalon - metencephalon - and reticular formation






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






18. PNS fibers that run towards CNS






19. Of pituitary - regulate water levels in body and therefore BP






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






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






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






23. (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






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






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






26. Outer covering of spine - nerve fibers - axon bundles - myelin sheathing






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






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






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






30. Of cerebral cortex - responsible for vision






31. 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






32. Midbrain; contains tectum and tegmentum






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






34. End of a neuron (terminal buttons)






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






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






37. Beginning of neuron (dendrites)






38. Protects the brain by making it difficult for toxic substances to pass from the blood into the brain - since blood vessel cells in the brain are tightly packed






39. Comprise two classes of neurotransmitters - indolamines and catecholamines






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






41. REM-sleep - low-amplitude and fast-frequency waves that characterize waking states






42. Of mesencephalon - vision and hearing






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






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






45. Connections between brain and spine






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






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






48. Bumps seen on cortex surface






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






50. Of pituitary - activates thyroid
