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






2. A single - unfertilized cell created during conception; the combined egg + sperm






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






4. Produce drowsiness and sleepiness






5. 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






6. Causes mesolimbic dopamine hyperactivity; etiology of schizophrenia






7. These cells perform a variety of functions but do not transmit information; one type forms the myelin sheath






8. Synchronized EEG activity during its deeper stages






9. Cumulative effects of repeated stimulation from a presynaptic neuron






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






11. Includes the tectum and tegmentum






12. Made from within - natural






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






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






15. Binding of a drug to a receptor site that does not interfere with the binding site for the principal ligand






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






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






18. A region of the visual association cortex located in the extrastriate cortex at the base of the brain that has special face-recognizing circuits (more important in right hemisphere)






19. 'Roof'






20. 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)






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






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






23. Is regulated by the hypothalamus






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






25. Involved in the effects of odors/pheromones in reproductive behavior - a nucleus that receives olfactory information from the olfactory bulb and accessory olfactory bulb






26. Contains receptors to detect when the body needs food or fluids; the hunger center; lesions lead to aphagia






27. EEG desynchrony (rapid -irregular waves) - lack of muscle tonus - rapid eye movements - penile erection/vaginal secretion - dreams; EEG synchrony (slow waves) - moderate muscle tonus - slow/absent eye movements - lack of genital activity






28. A 90-minute activity cycle occurs throughout the day as well as throughout sleep (in humans) waxing and waning alertness controlled by a biological clock in the caudal brainstem that also controls cycles of REM and slow-wave sleep






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






30. Adenine - Guanine - Thymine - Cytosine






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






32. Is a receptor blocker; binds with a receptor but does not activate it - actually prevents the natural ligand from binding with the receptor






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






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






35. Is characteristic of indirect antagonists






36. Some brain communications are with the same side of the body






37. Physiologically different from the other four stages of sleep (i.e. the similarity between the summed electrical activity of neurons measured on the scalp (EEG) during REM sleep and during wakefulness






38. A large network of neural tissue located in the central region of the brain stem - from the medulla to the diencephalon






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






40. 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






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






42. 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)

43. 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






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






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






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






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






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






49. Means 'Savory' in Japanese and is a taste receptor found on the tongue; activated by glutamate present in meats - cheese and other protein heavy foods






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