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






2. Occurs when their is damage to the septal area and results in unchecked aggressive and vicious behavior






3. Moving forward






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






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






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






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






8. The increase in REM sleep seen after a period of REM sleep deprivation






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






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






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






12. 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






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






14. 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)






15. Maintains balance/posture and coordinates body movements






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






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






18. Is increased in its production by training/experience and therefore - associated with memory






19. Located underneath the cerebral cortex and includes the bottom portion of the forebrain - cerebellum - basal ganglia - medulla - pons - midbrain - thalamus - hypothalamus - amygdala - hippocampus






20. 'little net'






21. One of the primary noradrenergic nuclei whose ascending axons project to frontal cortex - thalamus - hypothalamus - limbic system






22. An ovary or teste






23. 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)






24. 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






25. Transparent substance between lens and retina






26. 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)






27. Facial Nerve - moves face and salivates






28. 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)






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






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






31. 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






32. 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)






33. 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






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






35. Measure changes in the electrical resistance of the skin (sweat gland activity)






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






37. Termination of pregnancy by the odor of a pheromone in the urine of a male other than the one that impregnated the female; first observed in mice






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






39. 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

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






41. 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






42. 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






43. learning and memory -neurotransmitter released at the neuromuscular junction of skeletal muscle axons to excite the muscle to contract






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






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






46. Colored part of the eye






47. Includes comparative (evolution/genetics/animal behavior/ethology) and behavioral regulation






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






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






50. AKA the striate cortex - located at the back of the brain - and contains the visual cortex
