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






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






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






4. 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






5. Associated with defensive and aggressive behavior; lesions produce docility and hypersexual states (Kluver & Bucy)






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. Has two lobes that are connected by the massa intermedia (looks like a pair of balls - without the nutsack)






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






9. In the limbic system - is a fiber bundle - connects hippocampus with stuff (including the mammillary bodies of the hypothalamus)






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






11. Is found in the frontal lobe (which is divided into the prefrontal lobes and ___ ___)






12. Include the Nigrostriatal system - Mesolimbic system and Mesocortical system






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






14. Is found between the dura mater and arachnoid mater meninges






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






16. 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






17. Hormones that reduce pain






18. Involved in the effects of odors/pheromones in reproductive behavior - a nucleus that receives olfactory information from the olfactory bulb and accessory olfactory bulb






19. Symptom of narcolepsy - irresistible urge to






20. Olfactory Nerve - smell






21. The female reproductive cycle of most primates - including humans; recognized by growth of the lining of the uterus - ovulation - development of a corpus luteum - and (if pregnancy does not occur) menstration






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






23. Found in the ventricles and spinal canal






24. 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






25. 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)

26. 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






27. 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






28. 'little brain'






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






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






31. 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






32. Expression of traits






33. Choroid Plexus > Ventricle 1 & 2 > Foramen of Monro > Ventricle 3 > Aqueduct of Sylvius > Ventricle 4 > Foramen of Magendie lateral aperture) > Foramina of Luschka (lateral aperture) - subarachnoid space (outside of brain) and spinal cord > re-absorp






34. Is everything anterior to the central sulcus






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






36. 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)






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






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






39. Precursor to GABA (the most inhibitory/regulatory/pervasive neurotransmitter)






40. Colored part of the eye






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






42. Cumulative effects of repeated stimulation from a presynaptic neuron






43. Begins where spinal cord ends - 3 structures: the medulla - the pons - the cerebellum






44. Synchronized EEG activity during its deeper stages






45. Is characteristic of indirect antagonists






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






47. Absolute; relative






48. Maintains balance/posture and coordinates body movements






49. Areas in the brain receiving incoming sensory information or sending out motor-impulse commands






50. 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
