Question

a closer look tracking down cns problems
when a doctor taps your patellar tendon with a reflex hammer, your thigh muscles contract, resulting in the knee - jerk response. this response shows that the spinal cord and upper ( 1. ) centers are functioning normally. when reflex tests are abnormal, more sophisticated neurological tests may be ordered to try to localize and identify the problem.
an \oldie - but - goodie\ procedure used to ( 2. ) and localize many different types of brain lesions (such as epileptic lesions, tumors, and abscesses) is electroencephalography (e - lek*tro - en - sel - ah - lahgrah - fe). normal brain function involves the continuous transmission of electrical impulses by neurons. a recording of that ( 3. ) activity, called an electroencephalogram (eeg), can be made by placing electrodes at various points on the scalp and connecting these to a recording device, as in part (a) of the figure. the patterns of electrical activity are called brain waves. because people differ ( 4. ), and because everything we have ever experienced has left its imprint in our brain, each of us has a brain wave pattern that is as unique as our fingerprints. the four most commonly seen brain ( 5. ) are illustrated and described in part (b) of the figure

Explanation:

• For blank (1): "brain" makes sense as the spinal cord and upper brain centers are related in the context of neurological function.
• For blank (2): "diagnose" fits as electroencephalography is used to diagnose and localize brain lesions.
• For blank (3): "electrical" is correct as it refers to the electrical activity of neurons recorded in an EEG.
• For blank (4): "genetically" is appropriate as people differ genetically which contributes to unique brain wave patterns.
• For blank (5): "waves" is right as the four most commonly seen are brain waves.

Answer:

1. brain 2. diagnose 3. electrical 4. genetically 5. waves
