Ch. 3.3 - Brain

Question 1

peripheral nervous system (2)

Answer 1

• transmits info to and from the central nervous system
• breaks down into: autonomic nervous system and somatic nervous system, sympathetic division and parasympathetic division

Question 2

autonomic nervous system

Answer 2

regulates activity of the organs, glands and other physiological processes

Question 3

somatic nervous system

Answer 3

transmits sensory info and controls movement of skeletal muscles

Question 4

sympathetic division

Answer 4

prepares body to react and expend energy in times of stress

Question 5

parasympathetic division

Answer 5

maintains body functions; conserves resources

Question 6

central nervous system (2)

Answer 6

• brain: interprets and stores info and communicates with muscles, glands, and organs
• spinal cord: pathway connecting the brain and the PNS

Question 7

insights from brain damage (3)

Answer 7

• case studies of brain damage patients
• lesioning
• brain stimulation (transcranial magnetic stimulation TMS)

Question 8

structural neuroimaging (3)

Answer 8

• computarized tomography (CT)
• magnetic resonance imaging (MRI)
• diffusion tensor imaging (DTI)

Question 9

functional neuroimaging (3)

Answer 9

• electroencephalogram (EEG) event related potentials
• magnetoencephalography (MEG)
• position emission tomography (PET)

Question 10

functional magnetic resonance imaging (fMRA) (3)

Answer 10

• measures brain activity by detecting the influx of oxygen rich blood into neural areas that were just active
• data generated is correlational
• active regions may not be necessary for task
