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. 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






2. 3 layers of tissues that cover and protect CNS; dura mater (outermost layer) - arachnoid mater (middle layer) - Pia mater (innermost layer)






3. Norepinephrine and serotonin






4. 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






5. Glossopharyngeal Nerve - taste swallow






6. All have similar molecular structure - so many 'dirty' medications






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






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






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






10. Glandular system control center - produces the hormones oxytocin and antidiuretic; functions in both the nervous system and endocrine sytem - In the forebrain - regulates motivated behaviors (eating - drinking - aggression - sexual behavior






11. Oculomotor Nerve - moves eye pupil






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






13. Comprised of the hypothalamus - pituitary gland - thyroid gland - parathyroid - the adrenal cortex - the adrenal medulla - the pancreas - the ovaries/testes - pineal gland.






14. Are found in the diencephalon






15. Includes the tectum and tegmentum






16. Suggests that dreams are nothing more than the product of random electrical impulses (Hobson & McCarley)






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






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






19. The female reproductive cycle of mammals other than primates






20. Found that developmental changes occurring in puberty make the brain more susceptible to the psychotic effects of NDMA antagonist and therefore also related to the emergence of symptoms of schizophrenia






21. Decreasing effects of a medication due to repeated administration






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






23. Is increased in its production by training/experience and therefore - associated with memory






24. 'little brain'






25. Are postsynaptic potentials that are found in the dendrites and vary in their intensity






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






28. Bunch of dopaminergic neurons starting in the ventral tegmental area and ending in prefrontal cortex






29. Consummatory stimuli - sign stimuli - supernormal stimuli - releaser






30. If head is rotated - eye movements occur in the same direction






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






32. Optic Nerve - sight






33. Is generated by photoreceptors that are only sensitive to degrees of brightness; black-and-white vision found in the rods






34. Has neurons for reflexes






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






36. 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






37. Facial Nerve - moves face and salivates






38. Midbrain - medulla and the pons






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






40. Are direct antagonists; binds with a receptor but does not activate it - but prevents the natural ligand from binding with the receptor






41. Auditory receptor cells in the cochlea that turn sound vibrations -> neural impulses






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






43. 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






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






45. Occur in amacrine - bipolar and horizontal cells; govern/encompass the opponent-process level of color vision






46. Cumulative effects of repeated stimulation from a presynaptic neuron






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






48. ...






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






50. Expression of traits
