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. 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)






2. Suggests that dreams are nothing more than the product of random electrical impulses (Hobson & McCarley)






3. Holds the lens in place






4. Expression of traits






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






6. Emotional perception and expression (particularly fearful emotions and detection of threat)






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






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






9. Vision: protrusions on top of the midbrain; part of visual system






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






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






12. Is found between the arachnoid mater and Pia mater; this is where CSF cushions (and bathes) the brain - giving it the floating quality (and keeping it moist/circulating)






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






14. Optic Nerve - sight






15. Some brain communications are with the same side of the body






16. Consummatory stimuli - sign stimuli - supernormal stimuli - releaser






17. Affect multiple receptors; highly preferential to which type of receptor they affect






18. Is characteristic of indirect antagonists






19. Viscous substance between cornea and lens; transparent substance between lens and retina






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






21. 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






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






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






24. Found that developmental changes occurring in puberty make the brain more susceptible to the psychotic effects of NDMA antagonist and therefore also related to the emergence of symptoms of schizophrenia






25. Pass the easiest through the blood-brain barrier






26. 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






27. Is characteristic of indirect antagonist drugs






28. Is generated by photoreceptors that are only sensitive to degrees of brightness; black-and-white vision found in the rods






29. Strip of limbic cortex lying along the lateral walls of the groove separating the cerebral hemispheres - just above the corpus callosum






30. 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






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






32. An inherited form of defective color vision in which hues with short wavelengths are confused (blue cone dysfunction); see world in green and red






33. A drug that facilitates the effects of a particular neurotransmitter on the postsynaptic cell






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. 'Roof'






36. Produces acetylcholine. One of the earliest sites of cell death in Alzheimer'S Disease (neurological disorder associated with a deficiency in acetylcholine) is in the basal forebrain






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






38. The visual image of the world on the retina






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






40. 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)






41. Bunch of dopaminergic neurons starting in the ventral tegmental area and ending in the nucleus accumbens - amygdala and hippocampus






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






43. Research indicates that the expressing of negative emotions is associated with increased immune function; inhibiting negative emotions with decreasing immune function






44. Sleepwalking - sleep talking






45. Convoluted of hills (gyri) and valleys (sulci) divided into two hemispheres (left and right) which are further divided into four lobes (occipital - parietal - temporal and frontal)






46. 3 layers of tissues that cover and protect CNS; dura mater (outermost layer) - arachnoid mater (middle layer) - Pia mater (innermost layer)






47. The earlier onset of puberty seen in female animals that are housed with males caused by a pheromone in the male'S urine and first observed in mice






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






49. Synchronized EEG activity during its deeper stages






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