GRE Psychology: Physiological/behavioral Neuroscience 1

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. Time after a neuron fires which it cannot respond to stimulation






2. Made up of somatic nervous system and autonomic nervous system






3. Include serotonin - lack of serotonin is linked with depression






4. Of hindbrain - has pons(connects brain parts to spine) and cerebellum(controls muscle coordination - balance - posture)






5. Released at neuromuscular junction to cause contraction of skeletal muscles - also involved in parasympathetic nervous system






6. Measures brain wave patterns and have made it possible to study waking and sleeping states






7. Dysfunction in certain cortical association area - difficulty processing sensory information






8. PNS fibers that run away from CNS (to cause effect the brain wants)






9. Of cerebral cortex - responsible for somatosensory system






10. Outer covering of spine - nerve fibers - axon bundles - myelin sheathing






11. Bumps on the brainstem - controls visual reflexes






12. Include dopamine - lack of dopamine linked with Parkinson'S - excess dopamine is linked with schizophrenia - dopamine is also involved in feelings of reward and therefore addiction






13. Increase in males during puberty causes genitals to matures and secondary sex characteristics to develop - example: testosterone






14. Covers whole neuron - selective permeability - sometimes lets ions (positive charge) through






15. Consists of limbic system - hippocampus - amygdala - cingulate gyrus






16. Stage 3 (less sleep spindles) & 4 non-REM sleep - high-amplitude and low-frequency - deepest level of sleep






17. Beginning of neuron (dendrites)






18. Neuron branches - receive impulses - branching patterns change throughout life






19. Outer half-inch of cerebral hemispheres; - sensory and intellectual functions; - split into frontal - occipital - parietal - temporal lobes; - 90% is neocortex (new in evolution - 6 layers cortex) - 10% < 6 layers and more primitive






20. Bumps on the brainstem - controls auditory reflexes






21. Of telencephalon - involves in memory- transfer STM into LTM - - new neurons can form in adult mammalian brain






22. Overeating with no satiation of hunger; leads to obesity; damage to ventromedial region of hypothalamus






23. Between myelin sheath - help send impulse down axon






24. Dysfunction in certain cortical association area - inability to read






25. Areas on cortex that correspond to certain functions; - the larger the area - the more sensitive and highly accessed the function - Damage to a particular area would result in certain dysfunction






26. Inactivated state of a neuron






27. Pathway that runs to and from CNS






28. Midbrain; contains tectum and tegmentum






29. Low-amplitude and fast -frequency alpha waves






30. In females - regulate the development of ovum and trigger ovulation - In males - regulate the development of sperm cells and the production of testosterone






31. Occur during specific periods in development - permanent or long-lasting effects; - presence of H-Y antigen in development causes fetus to develop into a male - absence to female; - androgens in males and estrogen in females causes secondary sex cha






32. Process in which neural pathways are connected and then some die out (children go through these process)






33. Hyperpolarization - + let out - - compared to outside - decrease firing






34. A type of cell that help support neurons; oligodendrocytes and Schwann cells






35. Of telencephalon - controls emotional reactions such as fear and anger






36. (1) resting potential - neuron negatively charged - cell membrane does not let ions in; (2) presynaptic cell releases neurotransmitters from terminal buttons; (3) postsynaptic receptors in postsynaptic cells detects neurotransmitter and open ion chan






37. Base in hindbrain - rest in midbrain; oldest brain area; Controls alertness - thirst - sleep - involuntary muscles (i.e. heart)






38. 16 hours of sleep a day - 6 hours






39. Anytime during adulthood - short periods - often transient or reversible (current/recent circulation); - menstrual cycle (estradiol - progesterone - luteinizing hormone (LH) - follicle stimulating hormone (FSH)); - LH and FSH in females regulate ovum






40. Where soma and axon connect






41. An amino acid - most abundant excitatory neurotransmitter.






42. Changes in a nerve cell'S charge as the result of stimulation - 2 forms: excitatory postsynaptic potential and inhibitory postsynaptic potential






43. Present in fast-acting - directed synapses






44. ANS - controls arousal mechanisms (blood circulation - pupil dilation - threat and fear response) - Lie detector test relies on the premise -->lying activates the sympathetic nervous system and cause things like (increase heart rate - blood pressure






45. Associated with changes in hormone levels throughout the month - estradiol - progesterone - luteinizing hormone - follicle stimulating hormone






46. Dysfunction in certain cortical association area - inability to organize movement






47. Of mesencephalon - vision and hearing






48. Of diencephalon - controls autonomic nervous system biological motivations (hunger - thirst) and pituitary gland






49. Comprise two classes of neurotransmitters - indolamines and catecholamines






50. Provide myelin in peripheral nervous system
