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. Regulates body temperature






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






3. Is the primary inhibitory neurotransmitter in vertebrates; these receptors are ionotropic






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






5. Affect sex characteristics/development and produce estrogen/progesterone (in females - ovaries) and testosterone (in male - testes)






6. Occurs for body temperature - blood glucose levels - blood concentration - etc -hormones are important






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






8. 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)

9. Facial Nerve - moves face and salivates






10. Increases heartrate - dilates/constricts blood vessels - increases blood sugar - produces hormones epinephrine and norepinephrine






11. 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)






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






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






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






15. 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






16. ...






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






18. Consummatory stimulus






19. Those biological considerations which are IMMEDIATE;Behavioral/Cognitive Neuroscience (i.e. how the nervous and endocrine systems influence behaviors/thoughts)






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






21. Midbrain - medulla and the pons






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






23. Maintains balance/posture and coordinates body movements






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






25. Attaches to a binding site on receptor and interferes with the action of the receptor without affecting the binding site for the principal ligand (noncompetitive binding)






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






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






28. An inherited form of defective color vision in which hues with short wavelengths are confused (blue cone dysfunction); see world in green and red






29. Somewhat excitatory - also involved in synaptic plasticity - learning and short-term memory






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

31. 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






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






33. 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






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






35. 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






36. An ovary or teste






37. 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






38. Synchronized EEG activity during its deeper stages






39. Thymoleptics = relieves mania of bipolar disorder (lithium carbonate - valproic acid - carbamazepine)






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






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






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






43. Junction of the sagittal and coronal sutures of the skull; often used as a reference point for stereotaxic brain surgery






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






45. Projects to ventral tegmental area






46. Affect multiple receptors; highly preferential to which type of receptor they affect






47. Relays nerve impulses - processes sensory impulses - reflex behavior and contains nerve cell bodies






48. Most brain communications are with the opposite side of the body






49. 3 layers of tissues that cover and protect CNS; dura mater (outermost layer) - arachnoid mater (middle layer) - Pia mater (innermost layer)






50. Readiness with which molecules/drugs/medications join together; varies widely from medication to medication
