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. 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






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






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






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






5. 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

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






7. Ventral part of midbrain - includes periaqueductal gray matter - reticular formation - red nucleus - and substantia nigra






8. Is regulated by the hypothalamus






9. These two brain structures contain entry/exits for most of the cranial nerves and control vital functions (heart rate -digestion - respiration)






10. Also known as ABLATION - is any surgically induced brain lesion






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






12. 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)






13. 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






14. Optic Nerve - sight






15. Projects to ventral tegmental area






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






17. Cumulative effects of repeated stimulation from a presynaptic neuron






18. Lens changes initiated by the ciliary muscles to change the shape of the lens in order to focus image on the retina






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






20. 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)






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






22. Caudate nucleus and putamen






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






24. Acetylcholine - glutamate - gamma-aminobutyric acid - dopamine - serotonin - norepinephrine - endorphin






25. Cornea - aqueous humor - pupil - lens - vitreous humor - retina






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






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






28. Part of a glial cell that wraps around the axon of a neuron - providing insulation that facilitates speed of propagation of action potential






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






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






31. Pleasure center of the brain; discovered by Olds & Milner






32. Decreases with age up until age 30 - then begins to increase *(counter intuitive)*






33. 'little net'






34. The synchronization of the menstrual or estrous cycles of a group of females - which occurs only in the presence of a pheromone in a male'S urine






35. Pass the easiest through the blood-brain barrier






36. Produce drowsiness and sleepiness






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






38. Extensive research in dreams - said BAH to Freud; proposed the activation-synthesis hypothesis (dreams are nothing more than the product of random electrical impulses)






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






40. 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






41. Self-dissolving






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






43. Hormones that reduce pain






44. 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






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






46. Found in the ventricles and spinal canal






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






48. Trigerminal Nerve - face sensation






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






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