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. An ovary or teste






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






3. 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






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






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






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






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






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






9. Ventral part of midbrain - includes periaqueductal gray matter - reticular formation - red nucleus - and substantia nigra






10. Is characteristic of indirect antagonist drugs






11. Adenine - Guanine - Thymine - Cytosine






12. 'Roof'






13. Absolute; relative






14. Olfactory Nerve - smell






15. 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






16. Self-dissolving






17. 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






18. Lesions to this brain structure that is crucial to memory will produce anterograde amnesia






19. Reduces anxiety - released with NE in amygdala - hippocampus - basal ganglia - periaqueductal gray region - locus coeruleus and PFS; NPY is diminished in persons with PTSD/CPTSD and those exposed to chronic stress






20. In the tegmentum (ventral part of midbrain); its neurons connect to caudate nucleus + putamen (in basal ganglia)






21. Skin senses that register the sensations of pressure - warmth and cold






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






23. Irregular electrical activity of 13-30 Hz - state of arousal - attentive






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






25. The restorative effect of introducing a new female sex partner to a male that has apparently become 'exhausted' by sexual activity






26. Smooth electrical activity of 8-12 Hz -medium frequency - awake but in a restful state (^ eyes closed but conscious)






27. Has a major role in metabolism - stimulation/maintenance - produces the hormones thyroxin and calcitonin






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






29. Accessory Nerve - moves the head






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






31. Is an oversensitivity to dopamine (D2)






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






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






34. Hypothalamic-pituitary-adrenal axis -controls stress response






35. Sign






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






37. Symptom of narcolepsy; complete paralysis that occurs while AWAKE/conscious; will suddenly fall to floor paralyzed for a few minutes






38. 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






39. 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)






40. Abducens Nerve - moves eye






41. Receptors whose activation directly affects potassium or chloride ion channels in the neuron - (many drugs of abuse substitute for natural GABA- alcohol - benzos - barbituates






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






43. 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






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






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






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






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






48. Consummatory stimuli - sign stimuli - supernormal stimuli - releaser






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






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