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. Located in the midbrain - a group of neurons which produce dopamine and degenerate in Parkinson'S Disease






2. Midbrain - medulla and the pons






3. Regulates body temperature






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






5. Norepinephrine and serotonin






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






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






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






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






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






12. Is everything anterior to the central sulcus






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






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






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






16. Produces acetylcholine. One of the earliest sites of cell death in Alzheimer'S Disease (neurological disorder associated with a deficiency in acetylcholine) is in the basal forebrain






17. Trigerminal Nerve - face sensation






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






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






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






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






22. Controls circadian rhythms - produces melatonin (daylight signals go to the eyes to the hypothalamus to the pineal gland)






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






24. Olfactory Nerve - smell






25. Cumulative effects of repeated stimulation from a presynaptic neuron






26. A patient who had intact intelligence but an inability to learn/remember anything new (severe anterograde amnesia)






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






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






29. 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)






30. Important to motor system






31. Having two copies of each chromosomes in most cells (except the gametes) - e.g. most mammals






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






33. Controls sexual activity






34. Termination of pregnancy by the odor of a pheromone in the urine of a male other than the one that impregnated the female; first observed in mice






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






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






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






38. 3 layers of tissues that cover and protect CNS; dura mater (outermost layer) - arachnoid mater (middle layer) - Pia mater (innermost layer)






39. 'little net'






40. Absolute; relative






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






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






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






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






45. Is characteristic of indirect antagonist drugs






46. Most pervasive excitatory neurotransmitter in the brain






47. Optic Nerve - sight






48. Functions as both a hormone and a neurotransmitter in the brain






49. 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)






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