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. Self-dissolving






2. Precursor to GABA (the most inhibitory/regulatory/pervasive neurotransmitter)






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






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






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






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






7. Emotional perception and expression (particularly fearful emotions and detection of threat)






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






9. The increase in REM sleep seen after a period of REM sleep deprivation






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






11. Pass the easiest through the blood-brain barrier






12. Causes mesolimbic dopamine hyperactivity; etiology of schizophrenia






13. Regulates body temperature






14. Reduces anxiety - released with NE in amygdala - hippocampus - basal ganglia - periaqueductal gray region - locus coeruleus and PFS; NPY is diminished in persons with PTSD/CPTSD and those exposed to chronic stress






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






16. Receive incoming sensory information or send out motor impulse commands






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






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






19. Accessory Nerve - moves the head






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






21. 'Roof'






22. Found in the ventricles and spinal canal






23. Controls sexual activity






24. Caudate nucleus and putamen






25. The restorative effect of introducing a new female sex partner to a male that has apparently become 'exhausted' by sexual activity






26. 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






27. The visual image of the world on the retina






28. Adenine - Guanine - Thymine - Cytosine






29. The viscous substance between cornea and lens






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






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

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






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






34. Is everything anterior to the central sulcus






35. Cumulative effects of repeated stimulation from a presynaptic neuron






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






37. 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






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






39. Hormones that reduce pain






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






41. Is characteristic of indirect antagonist drugs






42. Controls circadian rhythms - produces melatonin (daylight signals go to the eyes to the hypothalamus to the pineal gland)






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






44. 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






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






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






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






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






49. Sits just above the hindbrain - contains cranial nerves - parts of the reticular formation -important relay stations for sensory information and the substantia nigra






50. Occurs when an external stimulation - regardless of intensity - will not trigger a new action potential
