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. Absolute; relative






2. Affect sex characteristics/development and produce estrogen/progesterone (in females - ovaries) and testosterone (in male - testes)






3. Expression of traits






4. Has two lobes that are connected by the massa intermedia (looks like a pair of balls - without the nutsack)






5. The Lee-Boot effect - Whitten effect - Vandenbergh effect - and the Bruce effect; all mediated by the VNO






6. Binding of a drug to a receptor site that does not interfere with the binding site for the principal ligand






7. Irregular electrical activity of 13-30 Hz - state of arousal - attentive






8. 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)






9. 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






10. Phantom limb pain - hypnotic induction and the success rate of placebo treatments






11. Part of a glial cell that wraps around the axon of a neuron - providing insulation that facilitates speed of propagation of action potential






12. 'little net'






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






14. Is an oversensitivity to dopamine (D2)






15. Is found in PTSD/CPTSD patients and persons exposed to chronic stress






16. Bunch of dopaminergic neurons starting in the ventral tegmental area and ending in the nucleus accumbens - amygdala and hippocampus






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






18. A drug that opposes/inhibits the effects of a particular neurotransmitter on the postsynaptic cell






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






20. One of the primary noradrenergic nuclei whose ascending axons project to frontal cortex - thalamus - hypothalamus - limbic system






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






22. Midbrain - medulla and the pons






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






24. In the CNS - is an amino acid that stabilizes neural activity






25. Has a calcium-related role and produces the hormone parathyroid






26. 1. Stage I (non-REM sleep) 2. Stage II (non-REM sleep 3. Stage III (non-REM sleep - slow-wave sleep) 4. Stage IV (non-REM sleep - slow-wave sleep) 5. Rapid Eye Movement Sleep (REM sleep) ~takes about 90 minutes for one full sleep cycle






27. Regulates body temperature






28. 1. ventral tegmentum to mesolimbic forebrain (cognition - reward systems - emotional behavior) 2. substantia nigra to caudate nucleus putamen (movement and sensory stimulation) 3. hypothalamus to pituitary gland (neuronal/hormonal control)






29. Colored part of the eye






30. Cumulative effects of repeated stimulation from a presynaptic neuron






31. Convoluted of hills (gyri) and valleys (sulci) divided into two hemispheres (left and right) which are further divided into four lobes (occipital - parietal - temporal and frontal)






32. Automatic and rapidly acquired reactions - not attributable to reinforcement or conditioning






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






34. Facial Nerve - moves face and salivates






35. 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






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






37. The maintenance of water balance in the body






38. learning and memory -neurotransmitter released at the neuromuscular junction of skeletal muscle axons to excite the muscle to contract






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






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






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






42. There are 12 add more






43. Acquired language disorders - usually caused by damage in the left hemisphere; includes Broca'S: (left frontal lobe damage) and Wernickes'S (left temporal/parietal damage)






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






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






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






47. Viscous substance between cornea and lens; transparent substance between lens and retina






48. 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






49. Transparent substance between lens and retina






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