Which of the following terms refers to typical patterns seen in EEG readings?

The term referring to typical patterns seen in EEG readings is known as normal waveforms. In the context of EEG, normal waveforms are the expected electrical activity patterns in a healthy brain. These patterns help clinicians distinguish between normal brain function and abnormalities that may indicate neurological disorders.

Normal waveforms encompass various types of brain activity, such as alpha, beta, theta, and delta waves, each associated with different states of consciousness and cognitive functions. Recognizing these standard patterns is crucial for properly interpreting EEG results and assessing brain health.

Other terms mentioned do not describe typical EEG patterns. Anomalous activities refer to unexpected or irregular electrical activities; pathological spikes indicate abnormal discharges often associated with epilepsy or other neurological conditions; and subclinical discharges suggest activity that does not produce clinical symptoms but may still be present in the EEG. Therefore, normal waveforms are the best choice to describe typical EEG patterns.
