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. Most pervasive excitatory neurotransmitter in the brain






2. Important to motor system






3. Abducens Nerve - moves eye






4. Fluid filled cavities in the middle of the brain - linking to the spinal canal that runs down the middle of the spinal cord; this fluid is cerebrospinal fluid






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






6. Mechanism whereby neurons make connections to new areas to change their connectivity






7. Auditory receptor cells in the cochlea that turn sound vibrations -> neural impulses






8. Is characteristic of indirect antagonists






9. Attaches to the binding site on a receptor and interferes with the receptor'S action - but NOT by interfering with the principal ligand'S binding site (noncompetitive binding)






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






11. 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






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






13. Portion of a sensory field to which a cell responds






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






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






16. Found in the ventricles and spinal canal






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






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






19. There are 12 add more






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






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






22. Opening in the iris; dilates and contracts allowing different levels of light in






23. Contains delta activity - stages III and IV






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






25. Activates one of 5 types of receptors in the CNS - cognition - motor activity - reward - muscle tone - sleep - mood - attention - learning -higher level effects of dopamine = D2






26. Is found in the frontal lobe (which is divided into the prefrontal lobes and ___ ___)






27. Motor neurons found in the Somatic (voluntary) and Autonomic (involuntary) Nervous Systems






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






29. Facial Nerve - moves face and salivates






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






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






32. SCN = controls circadian rhythms - located directly above the optic chasm in the anterior portion of the hypothalamus - receives input from the eyes which is why light exposure affects our sleep-wake cycles






33. Is an oversensitivity to dopamine (D2)






34. Those biological considerations which are IMMEDIATE;Behavioral/Cognitive Neuroscience (i.e. how the nervous and endocrine systems influence behaviors/thoughts)






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






36. Glossopharyngeal Nerve - taste swallow






37. Increases heartrate - dilates/constricts blood vessels - increases blood sugar - produces hormones epinephrine and norepinephrine






38. Emotional perception and expression (particularly fearful emotions and detection of threat)






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






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






41. Olfactory Nerve - smell






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






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






44. Automatic and rapidly acquired reactions - not attributable to reinforcement or conditioning






45. Oculomotor Nerve - moves eye pupil






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






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






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






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. Vagus Nerve - heart rate and digestion
