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. Increases heartrate - dilates/constricts blood vessels - increases blood sugar - produces hormones epinephrine and norepinephrine






2. Sleep tests (i.e. to diagnosis sleep apnea)






3. Located in the forebrain - basal ganglia -> movement -speech and other complex behaviors






4. Sits just above the hindbrain - contains cranial nerves - parts of the reticular formation -important relay stations for sensory information and the substantia nigra






5. Oculomotor Nerve - moves eye pupil






6. Includes the thalamus and hypothalamus; region of forebrain surrounding the 3rd ventricle






7. 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






8. Opening in the iris; dilates and contracts allowing different levels of light in






9. Those biological considerations which are IMMEDIATE;Behavioral/Cognitive Neuroscience (i.e. how the nervous and endocrine systems influence behaviors/thoughts)






10. Cumulative effects of repeated stimulation from a presynaptic neuron






11. There are 12 add more






12. ...






13. Controls circadian rhythms - produces melatonin (daylight signals go to the eyes to the hypothalamus to the pineal gland)






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






15. 'little net'






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






17. Caudate nucleus and putamen






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






19. Attaches to the binding site on a receptor and interferes with the receptor'S action - but NOT by interfering with the principal ligand'S binding site (noncompetitive binding)






20. Occurs during the deepest stages of slow-wave sleep; regular - synchronous electrical activity of less than 4 Hz






21. Automatic and rapidly acquired reactions - not attributable to reinforcement or conditioning






22. Focuses light waves on the retina and is held in place by the suspensory ligament; aqueous humor on cornea side; vitreous humor on retina side






23. Means 'Savory' in Japanese and is a taste receptor found on the tongue; activated by glutamate present in meats - cheese and other protein heavy foods






24. Stimulates bone growth and produces the hormones: somatotropin - prolactin - thyroid-stimulating - adrenocorticotropic (ACTH) - follicle-stimulating - luteinnizing






25. Occurs under drug-induced conditions - including excessive use of marijuana; high body temperature - autonomic instability and muscle rigidity






26. Having two copies of each chromosomes in most cells (except the gametes) - e.g. most mammals






27. Symptom of narcolepsy; complete paralysis that occurs while AWAKE/conscious; will suddenly fall to floor paralyzed for a few minutes






28. Olfactory Nerve - smell






29. Bunch of dopaminergic neurons starting in the ventral tegmental area and ending in prefrontal cortex






30. The slowing and eventual cessation of estrous cycles in groups of female animals that are housed together; caused by a pheromone in the animals urine and first observed in mice






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






32. The restorative effect of introducing a new female sex partner to a male that has apparently become 'exhausted' by sexual activity






33. Portion of a sensory field to which a cell responds






34. Projects to ventral tegmental area






35. A drug that opposes/inhibits the effects of a particular neurotransmitter on the postsynaptic cell






36. In the CNS - is an amino acid that stabilizes neural activity






37. 'covering'






38. Trigerminal Nerve - face sensation






39. A behavior that has different forms or occurs with different probabilities or under different circumstances in males than females






40. Receptors whose activation directly affects potassium or chloride ion channels in the neuron - (many drugs of abuse substitute for natural GABA- alcohol - benzos - barbituates






41. Tremors - rigidity of limbs - poor balance and difficulty initiating movements


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






43. Sudden - sharp waveforms found only in Stage II of sleep; spontaneously occur about one per minute but also to unexpected noises






44. Completely disactivates the prefrontal cortex (PFC); due to high levels of norepinephrine (NE)






45. Combines input from diverse brain regions; receives sensory information/sends motor impulses






46. Has neurons for reflexes






47. 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)


48. A steroid hormone produced by the ovary that maintains the endometrial lining of the uterus during the later part of the menstrual cycle and during pregnancy; along with estradiol it promotes receptivity in female mammals with estrous cycles






49. A BEHAVIOR; insistent urge of sleepiness forces us to seek sleep/a bad






50. Adenine - Guanine - Thymine - Cytosine
