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. 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






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






3. Glandular system control center - produces the hormones oxytocin and antidiuretic; functions in both the nervous system and endocrine sytem - In the forebrain - regulates motivated behaviors (eating - drinking - aggression - sexual behavior






4. The earlier onset of puberty seen in female animals that are housed with males caused by a pheromone in the male'S urine and first observed in mice






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






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






7. Are found in the diencephalon






8. 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






9. Cumulative effects of repeated stimulation from a presynaptic neuron






10. Absolute; relative






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






12. 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






13. Tremors - rigidity of limbs - poor balance and difficulty initiating movements

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






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






16. Symptom of narcolepsy - paralysis occurring just before a person falls alseep






17. There are 12 add more






18. Receive incoming sensory information or send out motor impulse commands






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






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






21. Is characteristic of indirect antagonist drugs






22. Hypothalamic-pituitary-adrenal axis -controls stress response






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






24. Controls circadian rhythms - produces melatonin (daylight signals go to the eyes to the hypothalamus to the pineal gland)






25. Two different presynaptic neurons/inputs to a post-synaptic cell






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






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






28. Reduces anxiety - released with NE in amygdala - hippocampus - basal ganglia - periaqueductal gray region - locus coeruleus and PFS; NPY is diminished in persons with PTSD/CPTSD and those exposed to chronic stress






29. 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






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






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






32. 'little brain'






33. 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






34. Is everything anterior to the central sulcus






35. Associated with (spoken) language reception/comprehension - memory processing - and emotional control; contains Wernicke'S area and the auditory cortex






36. Includes the thalamus and hypothalamus; region of forebrain surrounding the 3rd ventricle






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






38. These two developed the criteria for habituation; basic process is a form of synaptic depression that occurs presyntaptically.






39. 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)






40. Caudate nucleus and putamen






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






42. 'Roof'






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






44. 'covering'






45. Made from within - natural






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






47. An area that combines input from diverse brain regions






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






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






50. Completely disactivates the prefrontal cortex (PFC); due to high levels of norepinephrine (NE)
