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. The visual image of the world on the retina






2. 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






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






4. The slowing and eventual cessation of estrous cycles in groups of female animals that are housed together; caused by a pheromone in the animals urine and first observed in mice






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






6. A single - unfertilized cell created during conception; the combined egg + sperm






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






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






9. Some brain communications are with the same side of the body






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






11. Damage to this are causes clumsiness and loss of balance






12. Can occur after long term antipsychotic tx (opposite of Parkinson'S?); oversensitivity to dopamine






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






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






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






16. Are found in the diencephalon






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






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






19. A steroid hormone produced by the ovary that maintains the endometrial lining of the uterus during the later part of the menstrual cycle and during pregnancy; along with estradiol it promotes receptivity in female mammals with estrous cycles






20. SCN = controls circadian rhythms - located directly above the optic chasm in the anterior portion of the hypothalamus - receives input from the eyes which is why light exposure affects our sleep-wake cycles






21. 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






22. Is used to treat Parkinson'S Disease






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






24. Norepinephrine and serotonin






25. Consummatory stimulus






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






27. Is found between the arachnoid mater and Pia mater; this is where CSF cushions (and bathes) the brain - giving it the floating quality (and keeping it moist/circulating)






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






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






30. Means 'Savory' in Japanese and is a taste receptor found on the tongue; activated by glutamate present in meats - cheese and other protein heavy foods






31. Important to motor system






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






33. Transparent substance between lens and retina






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






35. Expression of traits






36. Oculomotor Nerve - moves eye pupil






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






38. Caudate nucleus and putamen






39. 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






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






41. ...






42. 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






43. Occurs during the deepest stages of slow-wave sleep; regular - synchronous electrical activity of less than 4 Hz






44. These two developed the criteria for habituation; basic process is a form of synaptic depression that occurs presyntaptically.






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






46. Decreasing effects of a medication due to repeated administration






47. Strip of limbic cortex lying along the lateral walls of the groove separating the cerebral hemispheres - just above the corpus callosum






48. Cumulative effects of repeated stimulation from a presynaptic neuron






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






50. Is everything anterior to the central sulcus
