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






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






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






4. 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






5. A peptide - also known as OREXIN - produced by neurons whose cell bodies are located in the hypothalamus; their destruction causes narcolepsy






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






7. Abducens Nerve - moves eye






8. Has neurons for reflexes






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






10. Optic Nerve - sight






11. 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






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






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

14. 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






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






16. The scientific study of animal behavior; documentation of species-specific instinctual behaviors






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






18. 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)






19. Motor neurons found in the Somatic (voluntary) and Autonomic (involuntary) Nervous Systems






20. Is regulated by the hypothalamus






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






22. Symptom of narcolepsy - irresistible urge to






23. Is characteristic of indirect antagonist drugs






24. 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

25. Similarity of alleles for a trait in an organism (i.e. heterozygous or homozygous)






26. An ovary or teste






27. Acquired language disorders - usually caused by damage in the left hemisphere; includes Broca'S: (left frontal lobe damage) and Wernickes'S (left temporal/parietal damage)






28. 'Roof'






29. The maintenance of water balance in the body






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






31. Follow Hering'S Opponent Process of color vision - and only have two types: red-green and yellow-blue; other levels of color vision are tri-chromatic






32. Are found in the diencephalon






33. 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






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






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






36. An area that combines input from diverse brain regions






37. Occurs intermittently during early stages of slow-wave sleep and REM sleep 3.5-7.5 Hz






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






39. 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)

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






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






42. Occurs at the onset of puberty; a hypothalamic hormone that stimulates the pituitary gland to secrete gonadotropin






43. Maintains balance/posture and coordinates body movements






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






45. The female reproductive cycle of mammals other than primates






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






47. hormone - secreted by the pituitary gland -signals the adrenal gland to secrete corticosteroid hormones -ACTH is a critical component of the HPA Axis that controls the stress response






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






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






50. Fluid filled cavities in the middle of the brain - linking to the spinal canal that runs down the middle of the spinal cord; this fluid is cerebrospinal fluid
