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. Trigerminal Nerve - face sensation






2. 1. ventral tegmentum to mesolimbic forebrain (cognition - reward systems - emotional behavior) 2. substantia nigra to caudate nucleus putamen (movement and sensory stimulation) 3. hypothalamus to pituitary gland (neuronal/hormonal control)






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






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






5. Most brain communications are with the opposite side of the body






6. 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)






7. Mechanism whereby neurons make connections to new areas to change their connectivity






8. An ovary or teste






9. 'little brain'






10. A BEHAVIOR; insistent urge of sleepiness forces us to seek sleep/a bad






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






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






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






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






15. 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

16. Include tolerance (possible withdrawal) and sensitivity






17. Is characteristic of indirect antagonists






18. Opening in the iris; dilates and contracts allowing different levels of light in






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






20. The female reproductive cycle of most primates - including humans; recognized by growth of the lining of the uterus - ovulation - development of a corpus luteum - and (if pregnancy does not occur) menstration






21. Moving forward






22. 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






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






24. Those biological considerations which are IMMEDIATE;Behavioral/Cognitive Neuroscience (i.e. how the nervous and endocrine systems influence behaviors/thoughts)






25. Occurs for body temperature - blood glucose levels - blood concentration - etc -hormones are important






26. Regulates body temperature






27. Stimulates bone growth and produces the hormones: somatotropin - prolactin - thyroid-stimulating - adrenocorticotropic (ACTH) - follicle-stimulating - luteinnizing






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






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






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






31. 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






32. Synchronized EEG activity during its deeper stages






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






34. Abducens Nerve - moves eye






35. Suggests that dreams are nothing more than the product of random electrical impulses (Hobson & McCarley)






36. 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






37. Glossopharyngeal Nerve - taste swallow






38. Is found at the base of the brain - underneath the thalamus (**remember hypo-below)






39. 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)






40. Short bursts of waves 12-14 Hz that occur 2-5 times a minute during stages 1-4 of sleep; most characteristic of sleep Stage II; some believe sleep spindles are involved in keeping one asleep (decline in older people)






41. Focuses light waves on the retina and is held in place by the suspensory ligament; aqueous humor on cornea side; vitreous humor on retina side






42. Located underneath the cerebral cortex and includes the bottom portion of the forebrain - cerebellum - basal ganglia - medulla - pons - midbrain - thalamus - hypothalamus - amygdala - hippocampus






43. A chemical released by one animal that affects the behavior or physiology of another animal; usually smelled or tasted






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






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






46. 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






47. 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)






48. A patient who had intact intelligence but an inability to learn/remember anything new (severe anterograde amnesia)






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






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