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






2. Most pervasive excitatory neurotransmitter in the brain






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






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






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






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






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






8. Trigerminal Nerve - face sensation






9. Produce drowsiness and sleepiness






10. Are found in the diencephalon






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






12. Maintains balance/posture and coordinates body movements






13. Absolute; relative






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






15. The viscous substance between cornea and lens






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






17. Midbrain - medulla and the pons






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






19. 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)






20. Occurs during the deepest stages of slow-wave sleep; regular - synchronous electrical activity of less than 4 Hz






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






22. Self-dissolving






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






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






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






26. Result in either tolerance (and possible withdrawal symptoms) or sensitization (increase effectiveness of the drug)






27. 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






28. Fluid filled cavities in the middle of the brain - linking to the spinal canal that runs down the middle of the spinal cord; this fluid is cerebrospinal fluid






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






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






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






32. A drug that opposes/inhibits the effects of a particular neurotransmitter on the postsynaptic cell






33. 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






34. Includes the tectum and tegmentum






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






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






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






38. 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






39. Glossopharyngeal Nerve - taste swallow






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






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






42. In the posterior frontal lobe - contains the somatosensory cortex (touch - pressure - temperature - pain)






43. Sleepwalking - sleep talking






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






45. Important to motor system






46. Is everything anterior to the central sulcus






47. Facial Nerve - moves face and salivates






48. 1. ventral tegmentum to mesolimbic forebrain (cognition - reward systems - emotional behavior) 2. substantia nigra to caudate nucleus putamen (movement and sensory stimulation) 3. hypothalamus to pituitary gland (neuronal/hormonal control)






49. 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






50. A chemical released by one animal that affects the behavior or physiology of another animal; usually smelled or tasted
