Chapter 8, Problem 1PI
Summary Introduction
To determine: The approximate duration of each wave in the given recording.
Introduction: Electroencephalography (EEG) is a technique that utilizes electrodes attached to the scalp to detect voltage fluctuations in neurons of the cerebral cortex due to the predominantly summed postsynaptic potentials. The voltage fluctuation in the neurons of the vertebral cortex is recorded as an electroencephalogram.
Expert Solution & Answer
Explanation of Solution
Refers Fig. 8.1 “EEG patterns are wavelike”. This figure shows a frequency of approximately 20 Hz, that is, 20 waves per second. The duration for each wave can be calculated as follows:
Conclusion
The approximate duration of each wave in the given recording is 50 msec.
