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. Include tolerance (possible withdrawal) and sensitivity






2. Occur in amacrine - bipolar and horizontal cells; govern/encompass the opponent-process level of color vision






3. Links the nervous system and endocrine system; comprised of involuntary efferent neurons and divided into the Sympathetic and Parasympathetic branches: Sympathetic Nervous System is involved in the 'fight or flight' response and the Parasympathetic N






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






5. Found in the hypothalamus - function to maintain the water balance in the body






6. Is a loss of dopamine cells in the substantia nigra of the basal ganglia; these cells are usually dark (nigra) but in Parkinson'S - the substantia nigra appears white due to cell death

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






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






9. Are postsynaptic potentials that are found in the dendrites and vary in their intensity






10. Receive incoming sensory information or send out motor impulse commands






11. Supernormal






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






13. Vagus Nerve - heart rate and digestion






14. In the posterior frontal lobe - contains the somatosensory cortex (touch - pressure - temperature - pain)






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






16. The viscous substance between cornea and lens






17. These cells perform a variety of functions but do not transmit information; one type forms the myelin sheath






18. Consummatory stimulus






19. Pleasure center of the brain; discovered by Olds & Milner






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






21. Moving forward






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






23. 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






24. Is found at the base of the brain - underneath the thalamus (**remember hypo-below)






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






26. The female reproductive cycle of mammals other than primates






27. Cells that integrate information across the retina; rather than sending signals toward the brain - amacrine cells link bipolar cells to other bipolar cells and ganglion cells to other ganglion cells






28. Decreases with age up until age 30 - then begins to increase *(counter intuitive)*






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






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






31. Controls sexual activity; lesions inhibit sexual behavior; stimulation increases aggressive sexual behavior






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






33. 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






34. 'little brain'






35. 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






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






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






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






39. Reduces anxiety - released with NE in amygdala - hippocampus - basal ganglia - periaqueductal gray region - locus coeruleus and PFS; NPY is diminished in persons with PTSD/CPTSD and those exposed to chronic stress






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






41. 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






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






43. Part of limbic system; protrusion of the bottom of the brain at the posterior end of the hypothalamus - contains some hypothalamic nuclei






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






45. Are direct antagonists; binds with a receptor but does not activate it - but prevents the natural ligand from binding with the receptor






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






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






48. Important to motor system






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






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