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. Pass the easiest through the blood-brain barrier






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






3. 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






4. Vestibulocochlear Nerve - hearing and balance






5. Cumulative effects of repeated stimulation from a presynaptic neuron






6. Is found in the interior rostral temporal lobe - part of limbic system






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






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






9. ...






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






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






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






13. Governs eating/drinking (lateral and ventromedial hypothalami) and sexual activity (anterior portion






14. Skin senses that register the sensations of pressure - warmth and cold






15. Sleepwalking - sleep talking






16. Optic Nerve - sight






17. In the posterior frontal lobe - contains the somatosensory cortex (touch - pressure - temperature - pain)






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






19. Synchronized EEG activity during its deeper stages






20. Eating - sex - aggression - sleep - focus on subcortical and neuroendocrine control of behavior






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






22. Sits just above the hindbrain - contains cranial nerves - parts of the reticular formation -important relay stations for sensory information and the substantia nigra






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






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






25. 'little brain'






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






27. In the tegmentum (ventral part of midbrain); its neurons connect to caudate nucleus + putamen (in basal ganglia)






28. Is regulated by the hypothalamus






29. Is an oversensitivity to dopamine (D2)






30. Holds the lens in place






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






32. Olfactory Nerve - smell






33. Is a receptor blocker; binds with a receptor but does not activate it - actually prevents the natural ligand from binding with the receptor






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






35. An inherited form of defective color vision in which hues with short wavelengths are confused (blue cone dysfunction); see world in green and red






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






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






38. Expression of traits






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






40. Cells that integrate information across the retina; rather than sending signals toward the brain - amacrine cells link bipolar cells to other bipolar cells and ganglion cells to other ganglion cells






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






42. Midbrain - medulla and the pons






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






44. Is generated by photoreceptors that are only sensitive to degrees of brightness; black-and-white vision found in the rods






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






46. The increase in REM sleep seen after a period of REM sleep deprivation






47. Symptom of narcolepsy; complete paralysis that occurs while AWAKE/conscious; will suddenly fall to floor paralyzed for a few minutes






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






49. Is characteristic of indirect antagonists






50. The midbrain; a region that surrounds the cerebral aqueduct; includes tectum and the tegmentum
