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. In the limbic system - is a fiber bundle - connects hippocampus with stuff (including the mammillary bodies of the hypothalamus)






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






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






4. 1. Stage I (non-REM sleep) 2. Stage II (non-REM sleep 3. Stage III (non-REM sleep - slow-wave sleep) 4. Stage IV (non-REM sleep - slow-wave sleep) 5. Rapid Eye Movement Sleep (REM sleep) ~takes about 90 minutes for one full sleep cycle






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






6. A chemical released by one animal that affects the behavior or physiology of another animal; usually smelled or tasted






7. Precursor to the catecholamine neurotransmitters (DA + NE)






8. These two developed the criteria for habituation; basic process is a form of synaptic depression that occurs presyntaptically.






9. 'little brain'






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






11. Self-dissolving






12. 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






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






14. Found in the ventricles and spinal canal






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






16. Associated with (spoken) language reception/comprehension - memory processing - and emotional control; contains Wernicke'S area and the auditory cortex






17. The maintenance of water balance in the body






18. Viscous substance between cornea and lens; transparent substance between lens and retina






19. There are 12 add more






20. Pleasure center of the brain; discovered by Olds & Milner






21. Is the primary inhibitory neurotransmitter in vertebrates; these receptors are ionotropic






22. Includes the thalamus and hypothalamus; region of forebrain surrounding the 3rd ventricle






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






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






25. Causes mesolimbic dopamine hyperactivity; etiology of schizophrenia






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






27. Referred to as the satiety center; lesions lead to obesity and hyperphagia






28. 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

29. Accessory Nerve - moves the head






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






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






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






33. 'covering'






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






35. Trigerminal Nerve - face sensation






36. EEG desynchrony (rapid -irregular waves) - lack of muscle tonus - rapid eye movements - penile erection/vaginal secretion - dreams; EEG synchrony (slow waves) - moderate muscle tonus - slow/absent eye movements - lack of genital activity






37. Maintains balance/posture and coordinates body movements






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






39. Is characteristic of indirect antagonists






40. One of the primary noradrenergic nuclei whose ascending axons project to frontal cortex - thalamus - hypothalamus - limbic system






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






42. Occurs when their is damage to the septal area and results in unchecked aggressive and vicious behavior






43. 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






44. 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






45. Symptom of narcolepsy - irresistible urge to






46. Is used to treat Parkinson'S Disease






47. Bunch of dopaminergic neurons starting in the substantia nigra and ending in the neostriatum






48. Attaches to a binding site on receptor and interferes with the action of the receptor without affecting the binding site for the principal ligand (noncompetitive binding)






49. 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






50. Has a major role in metabolism - stimulation/maintenance - produces the hormones thyroxin and calcitonin
