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






2. Holds the lens in place






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






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






5. If a synapse is active at about the same time that a postsynaptic neuron is active - that synapse will be strengthened






6. 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






7. 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)






8. An ovary or teste






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






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






11. The synchronization of the menstrual or estrous cycles of a group of females - which occurs only in the presence of a pheromone in a male'S urine






12. Cumulative effects of repeated stimulation from a presynaptic neuron






13. Two different presynaptic neurons/inputs to a post-synaptic cell






14. Consummatory stimuli - sign stimuli - supernormal stimuli - releaser






15. 'little brain'






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






17. Are found in the diencephalon






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






19. Most pervasive excitatory neurotransmitter in the brain






20. Important to motor system






21. The visual image of the world on the retina






22. Expression of traits






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






24. Vagus Nerve - heart rate and digestion






25. Binding of a drug to a receptor site that does not interfere with the binding site for the principal ligand






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






27. 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

28. Hormones that reduce pain






29. The viscous substance between cornea and lens






30. Dorsal part of midbrain; includes the superior and inferior colliculi






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






32. Regulates body temperature






33. Has neurons for reflexes






34. Pass the easiest through the blood-brain barrier






35. 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






36. Functions in metabolism (carbohydrate - protein - lipid) and in the endocrine system'S salt/water balance - produces the hormones cortisol and aldosterone






37. 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






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






39. Oculomotor Nerve - moves eye pupil






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






41. Controls circadian rhythms - produces melatonin (daylight signals go to the eyes to the hypothalamus to the pineal gland)






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






43. 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)






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






45. 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






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






47. Part of a glial cell that wraps around the axon of a neuron - providing insulation that facilitates speed of propagation of action potential






48. Precursor to the catecholamine neurotransmitters (DA + NE)






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






50. Optic Nerve - sight
