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. Reduces anxiety - released with NE in amygdala - hippocampus - basal ganglia - periaqueductal gray region - locus coeruleus and PFS; NPY is diminished in persons with PTSD/CPTSD and those exposed to chronic stress






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






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






4. 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






5. A behavior that has different forms or occurs with different probabilities or under different circumstances in males than females






6. Links the nervous system and endocrine system; comprised of involuntary efferent neurons and divided into the Sympathetic and Parasympathetic branches: Sympathetic Nervous System is involved in the 'fight or flight' response and the Parasympathetic N






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






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






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






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






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






12. 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

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






14. Binding of drug to receptor site that doesn'T interfere with the principal ligand






15. The Lee-Boot effect - Whitten effect - Vandenbergh effect - and the Bruce effect; all mediated by the VNO






16. Research indicates that the expressing of negative emotions is associated with increased immune function; inhibiting negative emotions with decreasing immune function






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






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






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






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






21. 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






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






23. Is used as an anaesthetic for children and animals but causes psychosis in adults






24. 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)






25. Has a calcium-related role and produces the hormone parathyroid






26. Midbrain - medulla and the pons






27. Hormones that reduce pain






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






29. Expression of traits






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






31. Occurs at the onset of puberty; a hypothalamic hormone that stimulates the pituitary gland to secrete gonadotropin






32. Transparent substance between lens and retina






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






34. Sign






35. A sensory organ that detects the presence of certain chemicals - especially when a liquid is actively sniffed; mediates the effects of some pheromones






36. A region of the visual association cortex located in the extrastriate cortex at the base of the brain that has special face-recognizing circuits (more important in right hemisphere)






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






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






39. Has two lobes that are connected by the massa intermedia (looks like a pair of balls - without the nutsack)






40. States that performance is worst at extremely low or extremely high levels of arousal and optimally at an intermediate level






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






42. Found in the ventricles and spinal canal






43. Controls sexual activity






44. Forebrain -band of nerve fibers connecting the two cerebral hemispheres






45. Is used to treat Parkinson'S Disease






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






47. The viscous substance between cornea and lens






48. 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






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






50. Similarity of alleles for a trait in an organism (i.e. heterozygous or homozygous)
