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






2. Sudden - sharp waveforms found only in Stage II of sleep; spontaneously occur about one per minute but also to unexpected noises






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






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






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






6. Pass the easiest through the blood-brain barrier






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






8. 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






9. Related to plasticity - the term Lashley used to describe different parts of the cortex being interchangeable in their roles in learning






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






11. 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)






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






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






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






15. 1. Stage I (non-REM sleep) 2. Stage II (non-REM sleep 3. Stage III (non-REM sleep - slow-wave sleep) 4. Stage IV (non-REM sleep - slow-wave sleep) 5. Rapid Eye Movement Sleep (REM sleep) ~takes about 90 minutes for one full sleep cycle






16. Hormones that reduce pain






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






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






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






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






21. Sleep tests (i.e. to diagnosis sleep apnea)






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






23. Abducens Nerve - moves eye






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






25. Result in either tolerance (and possible withdrawal symptoms) or sensitization (increase effectiveness of the drug)






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






27. Adenine - Guanine - Thymine - Cytosine






28. Activates one of 5 types of receptors in the CNS - cognition - motor activity - reward - muscle tone - sleep - mood - attention - learning -higher level effects of dopamine = D2






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






30. 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






31. 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






32. Is found in the frontal lobe (which is divided into the prefrontal lobes and ___ ___)






33. Auditory receptor cells in the cochlea that turn sound vibrations -> neural impulses






34. There are 12 add more






35. Controls sexual activity






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






37. Occurs at the onset of puberty; a hypothalamic hormone that stimulates the pituitary gland to secrete gonadotropin






38. Accessory Nerve - moves the head






39. AKA the striate cortex - located at the back of the brain - and contains the visual cortex






40. An ovary or teste






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






42. Causes mesolimbic dopamine hyperactivity; etiology of schizophrenia






43. Consummatory stimuli - sign stimuli - supernormal stimuli - releaser






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