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. Made up of brain and spinal cord






2. For female - the onset of the menstrual cycles - occurs during puberty






3. Where soma and axon connect






4. 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






5. comprises 50% of total sleep at birth - decreases to 25% - 20% sleep time spent in this type of sleep - Interspersed with non-REM every 30-40min - where dreams are experience - characterized by neural desynchrony - also known as paradoxical sleep -->






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






7. Dysfunction in certain cortical association area - inability to write






8. Chemicals that stimulate nearby cells






9. Occurs when people deprived of REM sleep - compensate by spending more time in REM sleep later in the night






10. 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






11. Of cerebral cortex - controls speech (Broca'S area) - reasoning - problem solving






12. PNS fibers that run towards CNS






13. Comprise two classes of neurotransmitters - indolamines and catecholamines






14. Of cerebral cortex - responsible for vision






15. 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






16. Inactivated state of a neuron






17. Extension of the spine - developed from base to the front






18. Incredible rage easily provoked when cerebral cortex is removed






19. Of pituitary - regulate water levels in body and therefore BP






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






21. Present in fast-acting - directed synapses






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






23. Pathway that runs to and from CNS






24. Holds neurotransmitters






25. Of mesencephalon - rest of reticular formation; Also involved in the sensorimotor system - analgesic effect of opiates






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






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






28. The process after a neurotransmitter has done its job - it is reabsorbed by the presynaptic cell






29. Depolarization - + from outside allowed into cell - increase firing






30. Low-amplitude and fast -frequency alpha waves






31. Stage 1 & 2 non-REM sleep (with sleep spindles) - lower-amplitude and slower frequency waves






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






33. Of cerebral cortex - responsible for hearing - also Wernicke'S area (related to speech)






34. Of Hindbrain - aka medulla; Mainly controls for reflexes - but also controls sleep - attention - movement






35. Fast frequency bursts of brain activity - inhibits processing to keep tranquil state






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






37. Linked to pleasure and analgesia; can be endogenous (opioid peptides) or exogenous (morphine or heroin) - Exogenous endorphine are highly addictive






38. Tough connective tissues that cover/protect brain and spinal cord






39. Divided into diencephalon and telencephalon






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






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






42. Measures oxygen flow in different brain areas - used most in cognitive psych to measure activity in different brain regions during certain tasks






43. Of cerebral cortex - responsible for somatosensory system






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






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






46. Consists of myelencephalon - metencephalon - and reticular formation






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






48. The basic unit of the nervous system - Consist of: Dentrites - cell body (soma) - axon hillock - axon - myelin sheath - nodes of Ranvier - Terminal buttons - cell membrane - synapse - glial cells






49. Contain synaptic vessels that hold neurotransmitters






50. 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
