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






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






3. Contains delta activity - stages III and IV






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






5. Short bursts of waves 12-14 Hz that occur 2-5 times a minute during stages 1-4 of sleep; most characteristic of sleep Stage II; some believe sleep spindles are involved in keeping one asleep (decline in older people)






6. Actually are two kinds: monochorionic and dichorionic (blastocyst splis into two before day 4)






7. Synchronized EEG activity during its deeper stages






8. A BEHAVIOR; insistent urge of sleepiness forces us to seek sleep/a bad






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






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






11. 'little net'






12. Stimulates bone growth and produces the hormones: somatotropin - prolactin - thyroid-stimulating - adrenocorticotropic (ACTH) - follicle-stimulating - luteinnizing






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






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






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






16. An axon of a neuron in one region of the brain whose terminals form synapses with neurons in another region






17. 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






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






19. Transparent substance between lens and retina






20. Extensive research in dreams - said BAH to Freud; proposed the activation-synthesis hypothesis (dreams are nothing more than the product of random electrical impulses)






21. Include the Nigrostriatal system - Mesolimbic system and Mesocortical system






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






23. 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)






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






25. Regulates body temperature






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






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






28. Vestibulocochlear Nerve - hearing and balance






29. Found in the ventricles and spinal canal






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






31. Pass the easiest through the blood-brain barrier






32. Optic Nerve - sight






33. 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






34. Vision: protrusions on top of the midbrain; part of visual system






35. 'little brain'






36. Most pervasive excitatory neurotransmitter in the brain






37. An area that combines input from diverse brain regions






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






39. Adenine - Guanine - Thymine - Cytosine






40. Olfactory Nerve - smell






41. Includes the tectum and tegmentum






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






43. Consummatory stimulus






44. Symptom of narcolepsy - irresistible urge to






45. The earlier onset of puberty seen in female animals that are housed with males caused by a pheromone in the male'S urine and first observed in mice






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






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






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






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






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