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. Dorsal part of midbrain; includes the superior and inferior colliculi






2. Damage to this are causes clumsiness and loss of balance






3. Consummatory stimuli - sign stimuli - supernormal stimuli - releaser






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






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






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






7. Regulates body temperature






8. The visual image of the world on the retina






9. Glossopharyngeal Nerve - taste swallow






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






11. Those biological considerations which are DISTANT; Evolutionary Psychology - Comparative Psychology - Ethology






12. Choroid Plexus > Ventricle 1 & 2 > Foramen of Monro > Ventricle 3 > Aqueduct of Sylvius > Ventricle 4 > Foramen of Magendie lateral aperture) > Foramina of Luschka (lateral aperture) - subarachnoid space (outside of brain) and spinal cord > re-absorp






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






14. There are 12 add more






15. Is increased in its production by training/experience and therefore - associated with memory






16. 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






17. Contains delta activity - stages III and IV






18. Increases heartrate - dilates/constricts blood vessels - increases blood sugar - produces hormones epinephrine and norepinephrine






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






20. 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






21. 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






22. 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






23. 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






24. Has two lobes that are connected by the massa intermedia (looks like a pair of balls - without the nutsack)






25. Absolute; relative






26. 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)

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






28. A behavior that has different forms or occurs with different probabilities or under different circumstances in males than females






29. 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






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






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






32. Found in the ventricles and spinal canal






33. Occurs intermittently during early stages of slow-wave sleep and REM sleep 3.5-7.5 Hz






34. Has neurons for reflexes






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






36. Sleepwalking - sleep talking






37. Oculomotor Nerve - moves eye pupil






38. Vestibulocochlear Nerve - hearing and balance






39. Pass the easiest through the blood-brain barrier






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






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






42. 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






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






44. 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

45. Transparent substance between lens and retina






46. Includes the tectum and tegmentum






47. Olfactory Nerve - smell






48. Is characteristic of indirect antagonist drugs






49. Found in the hypothalamus - function to maintain the water balance in the body






50. Cells that integrate information across the retina; rather than sending signals toward the brain - amacrine cells link bipolar cells to other bipolar cells and ganglion cells to other ganglion cells
