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. Some brain communications are with the same side of the body






2. The midbrain; a region that surrounds the cerebral aqueduct; includes tectum and the tegmentum






3. Projects to ventral tegmental area






4. 'little brain'






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






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






7. Receive incoming sensory information or send out motor impulse commands






8. Includes the tectum and tegmentum






9. The maintenance of water balance in the body






10. Is regulated by the hypothalamus






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






12. Norepinephrine and serotonin






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






14. 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






15. Emotional perception and expression (particularly fearful emotions and detection of threat)






16. A BEHAVIOR; insistent urge of sleepiness forces us to seek sleep/a bad






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






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






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






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






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






22. The visual image of the world on the retina






23. Extensive research in dreams - said BAH to Freud; proposed the activation-synthesis hypothesis (dreams are nothing more than the product of random electrical impulses)






24. Occurs under drug-induced conditions - including excessive use of marijuana; high body temperature - autonomic instability and muscle rigidity






25. Occurs when an external stimulation - regardless of intensity - will not trigger a new action potential






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






27. Is a peptide neurotransmitter and a natural painkiller and antianxiety






28. Colored part of the eye






29. 1. Stage I (non-REM sleep) 2. Stage II (non-REM sleep 3. Stage III (non-REM sleep - slow-wave sleep) 4. Stage IV (non-REM sleep - slow-wave sleep) 5. Rapid Eye Movement Sleep (REM sleep) ~takes about 90 minutes for one full sleep cycle






30. There are 12 add more






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






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






34. Also known as ABLATION - is any surgically induced brain lesion






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






36. Occurs when a neuron is hyperpolarized and characterized by sufficient strength of stimulation triggering a new action potential






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






38. Associated with (spoken) language reception/comprehension - memory processing - and emotional control; contains Wernicke'S area and the auditory cortex






39. The Lee-Boot effect - Whitten effect - Vandenbergh effect - and the Bruce effect; all mediated by the VNO






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






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






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






43. Caudate nucleus and putamen






44. When a neuron reaches its excitation threshold - the neuron will produce an action potential of FIXED amplitude regardless of the magnitude of the stimulation






45. 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






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






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






48. An axon of a neuron in one region of the brain whose terminals form synapses with neurons in another region






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






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