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. These cells perform a variety of functions but do not transmit information; one type forms the myelin sheath






2. An ovary or teste






3. Receptors whose activation directly affects potassium or chloride ion channels in the neuron - (many drugs of abuse substitute for natural GABA- alcohol - benzos - barbituates






4. Include indolamines (serotonin) and catecholamines (dopamine - norepinephrine and epinephrine)






5. ...






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






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






8. Is regulated by the hypothalamus






9. Lens changes initiated by the ciliary muscles to change the shape of the lens in order to focus image on the retina






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






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






12. Synchronized EEG activity during its deeper stages






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






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






15. 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






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






17. Is a peptide neurotransmitter and a natural painkiller and antianxiety






18. 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

19. Controls sexual activity






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






21. Sleepwalking - sleep talking






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






23. 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)






24. Combines input from diverse brain regions; receives sensory information/sends motor impulses






25. 'Roof'






26. Contains delta activity - stages III and IV






27. hormone - secreted by the pituitary gland -signals the adrenal gland to secrete corticosteroid hormones -ACTH is a critical component of the HPA Axis that controls the stress response






28. Involved in the effects of odors/pheromones in reproductive behavior - a nucleus that receives olfactory information from the olfactory bulb and accessory olfactory bulb






29. Fluid filled cavities in the middle of the brain - linking to the spinal canal that runs down the middle of the spinal cord; this fluid is cerebrospinal fluid






30. A 90-minute activity cycle occurs throughout the day as well as throughout sleep (in humans) waxing and waning alertness controlled by a biological clock in the caudal brainstem that also controls cycles of REM and slow-wave sleep






31. Expression of traits






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






33. Occurs under drug-induced conditions - including excessive use of marijuana; high body temperature - autonomic instability and muscle rigidity






34. 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






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






36. Lesions to this brain structure that is crucial to memory will produce anterograde amnesia






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






38. Are found in the diencephalon






39. 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






40. Bunch of dopaminergic neurons starting in the ventral tegmental area and ending in prefrontal cortex






41. Begins where spinal cord ends - 3 structures: the medulla - the pons - the cerebellum






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






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






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






45. Readiness with which molecules/drugs/medications join together; varies widely from medication to medication






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






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






48. Oculomotor Nerve - moves eye pupil






49. The synchronization of the menstrual or estrous cycles of a group of females - which occurs only in the presence of a pheromone in a male'S urine






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