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






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






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






4. Occurs when a neuron is hyperpolarized and characterized by sufficient strength of stimulation triggering a new action potential






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






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






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






8. If head is rotated - eye movements occur in the same direction






9. Produce drowsiness and sleepiness






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






11. Located in the forebrain - basal ganglia -> movement -speech and other complex behaviors






12. Absolute; relative






13. Moving forward






14. 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)






15. 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






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






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






18. Governs eating/drinking (lateral and ventromedial hypothalami) and sexual activity (anterior portion






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






20. Located in the midbrain - a group of neurons which produce dopamine and degenerate in Parkinson'S Disease






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






22. The viscous substance between cornea and lens






23. In the limbic system - is a fiber bundle - connects hippocampus with stuff (including the mammillary bodies of the hypothalamus)






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






25. 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)






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






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






28. An area that combines input from diverse brain regions






29. Causes mesolimbic dopamine hyperactivity; etiology of schizophrenia






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






31. 'little net'






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






33. Is the primary inhibitory neurotransmitter in vertebrates; these receptors are ionotropic






34. Expression of traits






35. Strip of limbic cortex lying along the lateral walls of the groove separating the cerebral hemispheres - just above the corpus callosum






36. 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






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






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






39. Has neurons for reflexes






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






41. 'little brain'






42. 'Roof'






43. Bunch of dopaminergic neurons starting in the substantia nigra and ending in the neostriatum






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






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






47. Regulates body temperature






48. Is used as an anaesthetic for children and animals but causes psychosis in adults






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






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