Question

as might be expected, brain - wave patterns while a person is wide awake differ from those that occur during relaxation or deep sleep. brain waves that are too fast or too slow suggest that the function of the cerebral cortex has been compromised, and (1. ) occurs at both extremes. sleep and coma result in brain - wave patterns that are slower than normal, whereas epileptic seizures and some kinds of drug overdose cause abnormally fast brain waves. because brain waves are seen even during (2. ), the absence of brain waves (a flat eeg) is taken as evidence of clinical death.
new imaging techniques (described in chapter 1, pp 17 - 18) have revolutionized the (3. ) of brain lesions. together, computed tomography (ct) and magnetic resonance imaging (mri) scans allow quick identification of most (4. ), intracranial lesions, multiple sclerosis plaques, and areas of dead brain tissue (infarcts). positron emission tomography (pet) scans can localize lesions that generate (5. ) seizures.

Explanation:

• For the first blank, "unconsciousness" makes sense as it occurs at both extremes (too fast or too slow brain - waves). Sleep and coma are related to unconscious states.
• For the second blank, "coma" is a state where brain - waves are still present (unlike clinical death with flat EEG).
• For the third blank, "diagnosis" of brain lesions is what new imaging techniques revolutionize.
• For the fourth blank, "tumors" are one of the things CT and MRI can identify along with other brain - related issues.
• For the fifth blank, "epileptic" seizures are what PET scans can localize the lesions for.
