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. Located underneath the cerebral cortex and includes the bottom portion of the forebrain - cerebellum - basal ganglia - medulla - pons - midbrain - thalamus - hypothalamus - amygdala - hippocampus






2. A drug that facilitates the effects of a particular neurotransmitter on the postsynaptic cell






3. These cells perform a variety of functions but do not transmit information; one type forms the myelin sheath






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






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






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






7. Self-dissolving






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






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






10. Referred to as the satiety center; lesions lead to obesity and hyperphagia






11. 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






12. Bunch of dopaminergic neurons starting in the ventral tegmental area and ending in the nucleus accumbens - amygdala and hippocampus






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






14. Can occur after long term antipsychotic tx (opposite of Parkinson'S?); oversensitivity to dopamine






15. Accessory Nerve - moves the head






16. 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)






17. The scientific study of animal behavior; documentation of species-specific instinctual behaviors






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






19. Synchronized EEG activity during its deeper stages






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






21. Transparent substance between lens and retina






22. Trigerminal Nerve - face sensation






23. Is the primary inhibitory neurotransmitter in vertebrates; these receptors are ionotropic






24. Causes mesolimbic dopamine hyperactivity; etiology of schizophrenia






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






26. SCN = controls circadian rhythms - located directly above the optic chasm in the anterior portion of the hypothalamus - receives input from the eyes which is why light exposure affects our sleep-wake cycles






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






28. An area that combines input from diverse brain regions






29. Produces acetylcholine. One of the earliest sites of cell death in Alzheimer'S Disease (neurological disorder associated with a deficiency in acetylcholine) is in the basal forebrain






30. 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






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






32. Means 'Savory' in Japanese and is a taste receptor found on the tongue; activated by glutamate present in meats - cheese and other protein heavy foods






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






34. Glossopharyngeal Nerve - taste swallow






35. Is regulated by the hypothalamus






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






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






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






39. Controls sexual activity






40. Symptom of narcolepsy - irresistible urge to






41. Facial Nerve - moves face and salivates






42. Hormone secreted during the night by the pineal body; role in circadian and seasonal rhythms






43. Tremors - rigidity of limbs - poor balance and difficulty initiating movements

44. Cornea - aqueous humor - pupil - lens - vitreous humor - retina






45. Short bursts of waves 12-14 Hz that occur 2-5 times a minute during stages 1-4 of sleep; most characteristic of sleep Stage II; some believe sleep spindles are involved in keeping one asleep (decline in older people)






46. Midbrain - medulla and the pons






47. Decreases with age up until age 30 - then begins to increase *(counter intuitive)*






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






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






50. Those biological considerations which are IMMEDIATE;Behavioral/Cognitive Neuroscience (i.e. how the nervous and endocrine systems influence behaviors/thoughts)
