Gre Psychology: Experimental/natural Science Biology

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. Is used as an anaesthetic for children and animals but causes psychosis in adults






2. Extensive research in dreams - said BAH to Freud; proposed the activation-synthesis hypothesis (dreams are nothing more than the product of random electrical impulses)






3. Physiologically different from the other four stages of sleep (i.e. the similarity between the summed electrical activity of neurons measured on the scalp (EEG) during REM sleep and during wakefulness






4. Absolute; relative






5. Instead of one continuum for sex (masculine-feminine) - her work in the presence of both masculine and feminine features/development suggests these are actually two separate continuums (defeminized-feminized and unmasculinized-masculinized)

6. Also known as ABLATION - is any surgically induced brain lesion






7. Has neurons for reflexes






8. Caudate nucleus and putamen






9. A patient who had intact intelligence but an inability to learn/remember anything new (severe anterograde amnesia)






10. AKA the striate cortex - located at the back of the brain - and contains the visual cortex






11. Smooth electrical activity of 8-12 Hz -medium frequency - awake but in a restful state (^ eyes closed but conscious)






12. Important to motor system






13. Is characteristic of indirect antagonists






14. Occurs when their is damage to the septal area and results in unchecked aggressive and vicious behavior






15. A region of the visual association cortex located in the extrastriate cortex at the base of the brain that has special face-recognizing circuits (more important in right hemisphere)






16. Oculomotor Nerve - moves eye pupil






17. Hormone secreted during the night by the pineal body; role in circadian and seasonal rhythms






18. Eating - sex - aggression - sleep - focus on subcortical and neuroendocrine control of behavior






19. Precursor to GABA (the most inhibitory/regulatory/pervasive neurotransmitter)






20. Occurs when a neuron is hyperpolarized and characterized by sufficient strength of stimulation triggering a new action potential






21. Part of a glial cell that wraps around the axon of a neuron - providing insulation that facilitates speed of propagation of action potential






22. These two developed the criteria for habituation; basic process is a form of synaptic depression that occurs presyntaptically.






23. Hormones that reduce pain






24. Actually are two kinds: monochorionic and dichorionic (blastocyst splis into two before day 4)






25. If head is rotated - eye movements occur in the same direction






26. All have similar molecular structure - so many 'dirty' medications






27. Can occur after long term antipsychotic tx (opposite of Parkinson'S?); oversensitivity to dopamine






28. Those biological considerations which are DISTANT; Evolutionary Psychology - Comparative Psychology - Ethology






29. Skin senses that register the sensations of pressure - warmth and cold






30. Short bursts of waves 12-14 Hz that occur 2-5 times a minute during stages 1-4 of sleep; most characteristic of sleep Stage II; some believe sleep spindles are involved in keeping one asleep (decline in older people)






31. Is an oversensitivity to dopamine (D2)






32. The visual image of the world on the retina






33. Produce drowsiness and sleepiness






34. Involved in the effects of odors/pheromones in reproductive behavior - a nucleus that receives olfactory information from the olfactory bulb and accessory olfactory bulb






35. Thymoleptics = relieves mania of bipolar disorder (lithium carbonate - valproic acid - carbamazepine)






36. Serotonin = 5-HT -regulation of mood - anxiety - aggression - sleep - appetite - sexuality -rostral and caudal raphe nuclei






37. Is found in PTSD/CPTSD patients and persons exposed to chronic stress






38. Contains receptors to detect when the body needs food or fluids; the hunger center; lesions lead to aphagia






39. Activates one of 5 types of receptors in the CNS - cognition - motor activity - reward - muscle tone - sleep - mood - attention - learning -higher level effects of dopamine = D2






40. Olfactory Nerve - smell






41. Is found in the frontal lobe (which is divided into the prefrontal lobes and ___ ___)






42. Increasing effects/effectiveness of a medication due to repeated administration






43. When a neuron reaches its excitation threshold - the neuron will produce an action potential of FIXED amplitude regardless of the magnitude of the stimulation






44. Facial Nerve - moves face and salivates






45. The increase in REM sleep seen after a period of REM sleep deprivation






46. Is characteristic of indirect antagonist drugs






47. SCN = controls circadian rhythms - located directly above the optic chasm in the anterior portion of the hypothalamus - receives input from the eyes which is why light exposure affects our sleep-wake cycles






48. A sensory organ that detects the presence of certain chemicals - especially when a liquid is actively sniffed; mediates the effects of some pheromones






49. Made from within - natural






50. Located in the midbrain - a group of neurons which produce dopamine and degenerate in Parkinson'S Disease
