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. 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






2. 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






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






4. Glossopharyngeal Nerve - taste swallow






5. Maintains balance/posture and coordinates body movements






6. Sudden - sharp waveforms found only in Stage II of sleep; spontaneously occur about one per minute but also to unexpected noises






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






8. Includes comparative (evolution/genetics/animal behavior/ethology) and behavioral regulation






9. 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






10. 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)






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






12. Is found at the base of the brain - underneath the thalamus (**remember hypo-below)






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






14. These two developed the criteria for habituation; basic process is a form of synaptic depression that occurs presyntaptically.






15. Sleepwalking - sleep talking






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






17. Symptom of narcolepsy - irresistible urge to






18. Has a calcium-related role and produces the hormone parathyroid






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






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






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






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






23. Hypoglossal Nerve - moves the tongue






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






25. Expression of traits






26. Is characteristic of indirect antagonists






27. Absolute; relative






28. Consummatory stimuli - sign stimuli - supernormal stimuli - releaser






29. Abducens Nerve - moves eye






30. Important to motor system






31. Facial Nerve - moves face and salivates






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






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






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






35. Trigerminal Nerve - face sensation






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






37. 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






38. States that performance is worst at extremely low or extremely high levels of arousal and optimally at an intermediate level






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






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






41. 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






42. Automatic and rapidly acquired reactions - not attributable to reinforcement or conditioning






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






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






45. Strip of limbic cortex lying along the lateral walls of the groove separating the cerebral hemispheres - just above the corpus callosum
