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






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


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






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






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






6. The visual image of the world on the retina






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






8. 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)






9. Most pervasive excitatory neurotransmitter in the brain






10. Decreasing effects of a medication due to repeated administration






11. The slowing and eventual cessation of estrous cycles in groups of female animals that are housed together; caused by a pheromone in the animals urine and first observed in mice






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






13. Located in the midbrain - a group of neurons which produce dopamine and degenerate in Parkinson'S Disease






14. The female reproductive cycle of mammals other than primates






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






16. Caudate nucleus and putamen






17. Sleepwalking - sleep talking






18. 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






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






20. Relays nerve impulses - processes sensory impulses - reflex behavior and contains nerve cell bodies






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






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






23. Fluid filled cavities in the middle of the brain - linking to the spinal canal that runs down the middle of the spinal cord; this fluid is cerebrospinal fluid






24. Causes mesolimbic dopamine hyperactivity; etiology of schizophrenia






25. An area that combines input from diverse brain regions






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






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






28. 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






29. learning and memory -neurotransmitter released at the neuromuscular junction of skeletal muscle axons to excite the muscle to contract






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






31. Sign






32. Produce drowsiness and sleepiness






33. Occurs when an external stimulation - regardless of intensity - will not trigger a new action potential






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






35. Has neurons for reflexes






36. Facial Nerve - moves face and salivates






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






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






39. Olfactory Nerve - smell






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






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






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






43. Serotonin = 5-HT -regulation of mood - anxiety - aggression - sleep - appetite - sexuality -rostral and caudal raphe nuclei






44. 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






45. Areas in the brain receiving incoming sensory information or sending out motor-impulse commands






46. Consummatory stimulus






47. Contains delta activity - stages III and IV






48. Is found in the interior rostral temporal lobe - part of limbic system






49. The viscous substance between cornea and lens






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