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






2. Phantom limb pain - hypnotic induction and the success rate of placebo treatments






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






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






5. A sensory organ that detects the presence of certain chemicals - especially when a liquid is actively sniffed; mediates the effects of some pheromones






6. The earlier onset of puberty seen in female animals that are housed with males caused by a pheromone in the male'S urine and first observed in mice






7. The maintenance of water balance in the body






8. Has neurons for reflexes






9. Neurotransmitter in CNS - hormone in peripheral vascular system; deficiencies > depression - ADD; noradrenergic nuclei = locus coeruleus






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






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






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






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






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






15. Accessory Nerve - moves the head






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






17. 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






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






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. Located in the forebrain - basal ganglia -> movement -speech and other complex behaviors






21. Pass the easiest through the blood-brain barrier






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






23. 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

24. EEG desynchrony (rapid -irregular waves) - lack of muscle tonus - rapid eye movements - penile erection/vaginal secretion - dreams; EEG synchrony (slow waves) - moderate muscle tonus - slow/absent eye movements - lack of genital activity






25. Bunch of dopaminergic neurons starting in the substantia nigra and ending in the neostriatum






26. 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






27. 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






28. Is an oversensitivity to dopamine (D2)






29. Oculomotor Nerve - moves eye pupil






30. Colored part of the eye






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






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






33. Involved in the effects of odors/pheromones in reproductive behavior - a nucleus that receives olfactory information from the olfactory bulb and accessory olfactory bulb






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






35. 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)






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






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






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






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






40. Symptom of narcolepsy - irresistible urge to






41. Olfactory Nerve - smell






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






43. Moving forward






44. Governs eating/drinking (lateral and ventromedial hypothalami) and sexual activity (anterior portion






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






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






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






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






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






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