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. 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)






2. Self-dissolving






3. Glandular system control center - produces the hormones oxytocin and antidiuretic; functions in both the nervous system and endocrine sytem - In the forebrain - regulates motivated behaviors (eating - drinking - aggression - sexual behavior






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






5. Expression of traits






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






7. Two different presynaptic neurons/inputs to a post-synaptic cell






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






9. 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






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






11. 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






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






13. Is everything anterior to the central sulcus






14. Sleep tests (i.e. to diagnosis sleep apnea)






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






16. Functions in metabolism (carbohydrate - protein - lipid) and in the endocrine system'S salt/water balance - produces the hormones cortisol and aldosterone






17. Controls sexual activity; lesions inhibit sexual behavior; stimulation increases aggressive sexual behavior






18. Irregular electrical activity of 13-30 Hz - state of arousal - attentive






19. Oculomotor Nerve - moves eye pupil






20. Norepinephrine and serotonin






21. Consummatory stimuli - sign stimuli - supernormal stimuli - releaser






22. A drug that facilitates the effects of a particular neurotransmitter on the postsynaptic cell






23. An area that combines input from diverse brain regions






24. The female reproductive cycle of mammals other than primates






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






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






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






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






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






30. 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






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






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






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






34. Midbrain - medulla and the pons






35. Audition: protrusions on top of midbrain; part of auditory system






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






37. Consummatory stimulus






38. Olfactory Nerve - smell






39. Areas in the brain receiving incoming sensory information or sending out motor-impulse commands






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






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






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






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






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






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






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






47. 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






48. The maintenance of water balance in the body






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






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