Gre Psychology: Experimental/natural Science Biology

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






2. 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)






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






4. Affect multiple receptors; highly preferential to which type of receptor they affect






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






6. Somewhat excitatory - also involved in synaptic plasticity - learning and short-term memory






7. Include tolerance (possible withdrawal) and sensitivity






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






9. Cumulative effects of repeated stimulation from a presynaptic neuron






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






11. Trochlear Nerve - moves eye






12. Occur in amacrine - bipolar and horizontal cells; govern/encompass the opponent-process level of color vision






13. Binding of a drug to a receptor site that does not interfere with the binding site for the principal ligand






14. 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)






15. 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






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






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






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






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






20. Junction of the sagittal and coronal sutures of the skull; often used as a reference point for stereotaxic brain surgery






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






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






23. Oculomotor Nerve - moves eye pupil






24. Holds the lens in place






25. Contains receptors to detect when the body needs food or fluids; the hunger center; lesions lead to aphagia






26. Sleepwalking - sleep talking






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






28. Is regulated by the hypothalamus






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






30. Choroid Plexus > Ventricle 1 & 2 > Foramen of Monro > Ventricle 3 > Aqueduct of Sylvius > Ventricle 4 > Foramen of Magendie lateral aperture) > Foramina of Luschka (lateral aperture) - subarachnoid space (outside of brain) and spinal cord > re-absorp






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






32. Controls sexual activity






33. The scientific study of animal behavior; documentation of species-specific instinctual behaviors






34. Is characteristic of indirect antagonists






35. Midbrain - medulla and the pons






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






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






38. If a synapse is active at about the same time that a postsynaptic neuron is active - that synapse will be strengthened






39. Is characteristic of indirect antagonist drugs






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






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






42. 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






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






44. Supernormal






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






46. Produce drowsiness and sleepiness






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






48. Includes the tectum and tegmentum






49. Maintains balance/posture and coordinates body movements






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