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. Receive incoming sensory information or send out motor impulse commands






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






3. Is a loss of dopamine cells in the substantia nigra of the basal ganglia; these cells are usually dark (nigra) but in Parkinson'S - the substantia nigra appears white due to cell death

4. Is everything anterior to the central sulcus






5. Is found between the dura mater and arachnoid mater meninges






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






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






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






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






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






11. ...






12. Motor neurons found in the Somatic (voluntary) and Autonomic (involuntary) Nervous Systems






13. Is found at the base of the brain - underneath the thalamus (**remember hypo-below)






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






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






16. Found in the hypothalamus - function to maintain the water balance in the body






17. Produce drowsiness and sleepiness






18. 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






19. Are found in the diencephalon






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






21. Occurs when a neuron is hyperpolarized and characterized by sufficient strength of stimulation triggering a new action potential






22. Hypoglossal Nerve - moves the tongue






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






24. Important to motor system






25. 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)






26. Accessory Nerve - moves the head






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






28. 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






29. Junction of the sagittal and coronal sutures of the skull; often used as a reference point for stereotaxic brain surgery






30. Caudate nucleus and putamen






31. Consummatory stimulus






32. 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






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






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






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






36. 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






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






38. Has neurons for reflexes






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






40. Supernormal






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






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






43. Olfactory Nerve - smell






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






45. The female reproductive cycle of mammals other than primates






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






47. Measure changes in the electrical resistance of the skin (sweat gland activity)






48. Extensive research in dreams - said BAH to Freud; proposed the activation-synthesis hypothesis (dreams are nothing more than the product of random electrical impulses)






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






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