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. 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)






2. 'little brain'






3. Is used as an anaesthetic for children and animals but causes psychosis in adults






4. Is a peptide neurotransmitter and a natural painkiller and antianxiety






5. Trochlear Nerve - moves eye






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






7. Somewhat excitatory - also involved in synaptic plasticity - learning and short-term memory






8. 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)






9. 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






10. Having two copies of each chromosomes in most cells (except the gametes) - e.g. most mammals






11. Adenine - Guanine - Thymine - Cytosine






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






13. Is regulated by the hypothalamus






14. Functions in metabolism (carbohydrate - protein - lipid) and in the endocrine system'S salt/water balance - produces the hormones cortisol and aldosterone






15. 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






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






17. Opening in the iris; dilates and contracts allowing different levels of light in






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






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






20. Contains receptors to detect when the body needs food or fluids; the hunger center; lesions lead to aphagia






21. Causes mesolimbic dopamine hyperactivity; etiology of schizophrenia






22. 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






23. Precursor to the catecholamine neurotransmitters (DA + NE)






24. ...






25. Occurs at the onset of puberty; a hypothalamic hormone that stimulates the pituitary gland to secrete gonadotropin






26. 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






27. Facial Nerve - moves face and salivates






28. 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






29. An area that combines input from diverse brain regions






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






31. Sleep tests (i.e. to diagnosis sleep apnea)






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






33. Includes the tectum and tegmentum






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






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






36. Affect multiple receptors; highly preferential to which type of receptor they affect






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






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






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






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






41. Refers to both the somatosensory cortex and motor cortex (they are a little different but very interrelated)






42. Dorsal part of midbrain; includes the superior and inferior colliculi






43. Synchronized EEG activity during its deeper stages






44. Readiness with which molecules/drugs/medications join together; varies widely from medication to medication






45. These two brain structures contain entry/exits for most of the cranial nerves and control vital functions (heart rate -digestion - respiration)






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






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






48. Oculomotor Nerve - moves eye pupil






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






50. Is found in the interior rostral temporal lobe - part of limbic system
