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. Contains receptors to detect when the body needs food or fluids; the hunger center; lesions lead to aphagia






2. 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


3. ...






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






5. Focuses light waves on the retina and is held in place by the suspensory ligament; aqueous humor on cornea side; vitreous humor on retina side






6. 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






7. Supernormal






8. 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






9. Is everything anterior to the central sulcus






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






11. Functions in metabolism (carbohydrate - protein - lipid) and in the endocrine system'S salt/water balance - produces the hormones cortisol and aldosterone






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






13. Similarity of alleles for a trait in an organism (i.e. heterozygous or homozygous)






14. 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)






15. First described by Descartes - a combination of antagonistic muscle movements (e.g. those involved in walking)






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






17. A large network of neural tissue located in the central region of the brain stem - from the medulla to the diencephalon






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






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






20. 'covering'






21. The female reproductive cycle of mammals other than primates






22. Optic Nerve - sight






23. Trigerminal Nerve - face sensation






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






25. 'little net'






26. AKA the striate cortex - located at the back of the brain - and contains the visual cortex






27. 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






28. Attaches to the binding site on a receptor and interferes with the receptor'S action - but NOT by interfering with the principal ligand'S binding site (noncompetitive binding)






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






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






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






32. Facial Nerve - moves face and salivates






33. Produce drowsiness and sleepiness






34. Occurs for body temperature - blood glucose levels - blood concentration - etc -hormones are important






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






36. 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






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


38. Oculomotor Nerve - moves eye pupil






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






40. Projects to ventral tegmental area






41. Pass the easiest through the blood-brain barrier






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






43. Result in either tolerance (and possible withdrawal symptoms) or sensitization (increase effectiveness of the drug)






44. Is found in the frontal lobe (which is divided into the prefrontal lobes and ___ ___)






45. Regulates body temperature






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






47. Increases heartrate - dilates/constricts blood vessels - increases blood sugar - produces hormones epinephrine and norepinephrine






48. Norepinephrine and serotonin






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






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