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 peptide - also known as OREXIN - produced by neurons whose cell bodies are located in the hypothalamus; their destruction causes narcolepsy






2. Sleepwalking - sleep talking






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






4. 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






5. Research indicates that the expressing of negative emotions is associated with increased immune function; inhibiting negative emotions with decreasing immune function






6. Acetylcholine - glutamate - gamma-aminobutyric acid - dopamine - serotonin - norepinephrine - endorphin






7. Holds the lens in place






8. Completely disactivates the prefrontal cortex (PFC); due to high levels of norepinephrine (NE)






9. Follow Hering'S Opponent Process of color vision - and only have two types: red-green and yellow-blue; other levels of color vision are tri-chromatic






10. An anterograde amnesia in which one cannot form episodic memories BUT in experiments - patients that cannot identify previously heard melodies do show a preference for them -> explicit memory function has a different neurological basis than implicit

11. Controls sexual activity






12. Relays nerve impulses - processes sensory impulses - reflex behavior and contains nerve cell bodies






13. Includes the thalamus and hypothalamus; region of forebrain surrounding the 3rd ventricle






14. When a neuron reaches its excitation threshold - the neuron will produce an action potential of FIXED amplitude regardless of the magnitude of the stimulation






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






16. An ovary or teste






17. Include tolerance (possible withdrawal) and sensitivity






18. Activates one of 5 types of receptors in the CNS - cognition - motor activity - reward - muscle tone - sleep - mood - attention - learning -higher level effects of dopamine = D2






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






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






21. Sign






22. Serotonin = 5-HT -regulation of mood - anxiety - aggression - sleep - appetite - sexuality -rostral and caudal raphe nuclei






23. Is regulated by the hypothalamus






24. Found in the ventricles and spinal canal






25. 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






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






27. 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)






28. Abducens Nerve - moves eye






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






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






31. Include indolamines (serotonin) and catecholamines (dopamine - norepinephrine and epinephrine)






32. Colored part of the eye






33. Ventral part of midbrain - includes periaqueductal gray matter - reticular formation - red nucleus - and substantia nigra






34. The female reproductive cycle of mammals other than primates






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






36. Eating - sex - aggression - sleep - focus on subcortical and neuroendocrine control of behavior






37. 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






38. Is everything anterior to the central sulcus






39. Attaches to the binding site on a receptor and interferes with the receptor'S action - but NOT by interfering with the principal ligand'S binding site (noncompetitive binding)






40. Most pervasive excitatory neurotransmitter in the brain






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






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






43. A patient who had intact intelligence but an inability to learn/remember anything new (severe anterograde amnesia)






44. Supernormal






45. Associated with (spoken) language reception/comprehension - memory processing - and emotional control; contains Wernicke'S area and the auditory cortex






46. 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






47. Accessory Nerve - moves the head






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






49. Links the nervous system and endocrine system; comprised of involuntary efferent neurons and divided into the Sympathetic and Parasympathetic branches: Sympathetic Nervous System is involved in the 'fight or flight' response and the Parasympathetic N






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