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. Precursor to GABA (the most inhibitory/regulatory/pervasive neurotransmitter)






2. Transparent substance between lens and retina






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






4. Instead of one continuum for sex (masculine-feminine) - her work in the presence of both masculine and feminine features/development suggests these are actually two separate continuums (defeminized-feminized and unmasculinized-masculinized)

5. Completely disactivates the prefrontal cortex (PFC); due to high levels of norepinephrine (NE)






6. Optic Nerve - sight






7. Actually are two kinds: monochorionic and dichorionic (blastocyst splis into two before day 4)






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






9. Is found in PTSD/CPTSD patients and persons exposed to chronic stress






10. 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






11. Is regulated by the hypothalamus






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






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






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






15. Causes mesolimbic dopamine hyperactivity; etiology of schizophrenia






16. Contains delta activity - stages III and IV






17. Suggests that dreams are nothing more than the product of random electrical impulses (Hobson & McCarley)






18. ...






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






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






21. Is found at the base of the brain - underneath the thalamus (**remember hypo-below)






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






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






24. 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)






25. Sleepwalking - sleep talking






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






27. 'Roof'






28. Combines input from diverse brain regions; receives sensory information/sends motor impulses






29. Is characteristic of indirect antagonists






30. 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

31. Affect sex characteristics/development and produce estrogen/progesterone (in females - ovaries) and testosterone (in male - testes)






32. Follow Hering'S Opponent Process of color vision - and only have two types: red-green and yellow-blue; other levels of color vision are tri-chromatic






33. Occurs under drug-induced conditions - including excessive use of marijuana; high body temperature - autonomic instability and muscle rigidity






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






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






36. 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






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






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






39. The earlier onset of puberty seen in female animals that are housed with males caused by a pheromone in the male'S urine and first observed in mice






40. Comprised of the hypothalamus - pituitary gland - thyroid gland - parathyroid - the adrenal cortex - the adrenal medulla - the pancreas - the ovaries/testes - pineal gland.






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






42. 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






43. Expression of traits






44. Projects to ventral tegmental area






45. Hormones that reduce pain






46. Facial Nerve - moves face and salivates






47. The female reproductive cycle of mammals other than primates






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






49. 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






50. Includes the tectum and tegmentum
