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. Synchronized EEG activity during its deeper stages






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






3. Is found between the dura mater and arachnoid mater meninges






4. Regulates body temperature






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






6. The female reproductive cycle of mammals other than primates






7. First described by Descartes - a combination of antagonistic muscle movements (e.g. those involved in walking)






8. The Lee-Boot effect - Whitten effect - Vandenbergh effect - and the Bruce effect; all mediated by the VNO






9. Found in the ventricles and spinal canal






10. Binding of drug to receptor site that doesn'T interfere with the principal ligand






11. Has a calcium-related role and produces the hormone parathyroid






12. Symptom of narcolepsy - paralysis occurring just before a person falls alseep






13. Vagus Nerve - heart rate and digestion






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






15. 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)






16. Causes mesolimbic dopamine hyperactivity; etiology of schizophrenia






17. Self-dissolving






18. Related to plasticity - the term Lashley used to describe different parts of the cortex being interchangeable in their roles in learning






19. The midbrain; a region that surrounds the cerebral aqueduct; includes tectum and the tegmentum






20. A large network of neural tissue located in the central region of the brain stem - from the medulla to the diencephalon






21. Cornea - aqueous humor - pupil - lens - vitreous humor - retina






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






23. Forebrain -band of nerve fibers connecting the two cerebral hemispheres






24. A single - unfertilized cell created during conception; the combined egg + sperm






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






26. Mechanism whereby neurons make connections to new areas to change their connectivity






27. Is found in the interior rostral temporal lobe - part of limbic system






28. Areas in the brain receiving incoming sensory information or sending out motor-impulse commands






29. A 90-minute activity cycle occurs throughout the day as well as throughout sleep (in humans) waxing and waning alertness controlled by a biological clock in the caudal brainstem that also controls cycles of REM and slow-wave sleep






30. Is a receptor blocker; binds with a receptor but does not activate it - actually prevents the natural ligand from binding with the receptor






31. Attaches to a binding site on receptor and interferes with the action of the receptor without affecting the binding site for the principal ligand (noncompetitive binding)






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






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






34. Colored part of the eye






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






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






37. Refers to both the somatosensory cortex and motor cortex (they are a little different but very interrelated)






38. Auditory receptor cells in the cochlea that turn sound vibrations -> neural impulses






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






40. Is characteristic of indirect antagonists






41. Referred to as the satiety center; lesions lead to obesity and hyperphagia






42. Governs eating/drinking (lateral and ventromedial hypothalami) and sexual activity (anterior portion






43. Damage to this are causes clumsiness and loss of balance






44. These two brain structures contain entry/exits for most of the cranial nerves and control vital functions (heart rate -digestion - respiration)






45. Irregular electrical activity of 13-30 Hz - state of arousal - attentive






46. The maintenance of water balance in the body






47. An area that combines input from diverse brain regions






48. 1. ventral tegmentum to mesolimbic forebrain (cognition - reward systems - emotional behavior) 2. substantia nigra to caudate nucleus putamen (movement and sensory stimulation) 3. hypothalamus to pituitary gland (neuronal/hormonal control)






49. EEG desynchrony (rapid -irregular waves) - lack of muscle tonus - rapid eye movements - penile erection/vaginal secretion - dreams; EEG synchrony (slow waves) - moderate muscle tonus - slow/absent eye movements - lack of genital activity






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