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






2. An inherited form of defective color vision in which hues with short wavelengths are confused (blue cone dysfunction); see world in green and red






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






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






5. 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






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






7. Produce drowsiness and sleepiness






8. Include indolamines (serotonin) and catecholamines (dopamine - norepinephrine and epinephrine)






9. Eating - sex - aggression - sleep - focus on subcortical and neuroendocrine control of behavior






10. Associated with defensive and aggressive behavior; lesions produce docility and hypersexual states (Kluver & Bucy)






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






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






13. Supernormal






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






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






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






17. Hormones that reduce pain






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






19. 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






20. Those biological considerations which are DISTANT; Evolutionary Psychology - Comparative Psychology - Ethology






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






22. In the tegmentum (ventral part of midbrain); its neurons connect to caudate nucleus + putamen (in basal ganglia)






23. Tremors - rigidity of limbs - poor balance and difficulty initiating movements

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






25. Increasing effects/effectiveness of a medication due to repeated administration






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






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






28. Includes the tectum and tegmentum






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






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






31. 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)






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






33. Absolute; relative






34. The visual image of the world on the retina






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






36. 1. ventral tegmentum to mesolimbic forebrain (cognition - reward systems - emotional behavior) 2. substantia nigra to caudate nucleus putamen (movement and sensory stimulation) 3. hypothalamus to pituitary gland (neuronal/hormonal control)






37. Olfactory Nerve - smell






38. Synchronized EEG activity during its deeper stages






39. Are postsynaptic potentials that are found in the dendrites and vary in their intensity






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






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






42. Refers to both the somatosensory cortex and motor cortex (they are a little different but very interrelated)






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






44. Accessory Nerve - moves the head






45. Is everything anterior to the central sulcus






46. 3 layers of tissues that cover and protect CNS; dura mater (outermost layer) - arachnoid mater (middle layer) - Pia mater (innermost layer)






47. Pass the easiest through the blood-brain barrier






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






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






50. Precursor to the catecholamine neurotransmitters (DA + NE)
