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. Is regulated by the hypothalamus






2. Phantom limb pain - hypnotic induction and the success rate of placebo treatments






3. Vestibulocochlear Nerve - hearing and balance






4. An ovary or teste






5. Contains delta activity - stages III and IV






6. Receive incoming sensory information or send out motor impulse commands






7. A drug that facilitates the effects of a particular neurotransmitter on the postsynaptic cell






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






9. 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)






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






11. Regulates body temperature






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






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






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






16. When a neuron reaches its excitation threshold - the neuron will produce an action potential of FIXED amplitude regardless of the magnitude of the stimulation






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






18. Are found in the diencephalon






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






20. Abducens Nerve - moves eye






21. Bunch of dopaminergic neurons starting in the ventral tegmental area and ending in the nucleus accumbens - amygdala and hippocampus






22. 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






23. Bunch of dopaminergic neurons starting in the ventral tegmental area and ending in prefrontal cortex






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






25. Causes mesolimbic dopamine hyperactivity; etiology of schizophrenia






26. 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






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






28. Holds the lens in place






29. 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






30. ...






31. Caudate nucleus and putamen






32. Synchronized EEG activity during its deeper stages






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






34. 3 layers of tissues that cover and protect CNS; dura mater (outermost layer) - arachnoid mater (middle layer) - Pia mater (innermost layer)






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






36. Absolute; relative






37. The slowing and eventual cessation of estrous cycles in groups of female animals that are housed together; caused by a pheromone in the animals urine and first observed in mice






38. The increase in REM sleep seen after a period of REM sleep deprivation






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






40. Olfactory Nerve - smell






41. 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)

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






43. Attaches to a binding site on receptor and interferes with the action of the receptor without affecting the binding site for the principal ligand (noncompetitive binding)






44. Trigerminal Nerve - face sensation






45. Sits just above the hindbrain - contains cranial nerves - parts of the reticular formation -important relay stations for sensory information and the substantia nigra






46. Areas in the brain receiving incoming sensory information or sending out motor-impulse commands






47. Midbrain - medulla and the pons






48. Vagus Nerve - heart rate and digestion






49. Is characteristic of indirect antagonist drugs






50. 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)
