This chapter briefly describes the various types of evoked and event-related responses that can be recorded in response to auditory stimulation, such as clicks and tones, and speech. Transient auditory-evoked responses are generally grouped into three major categories according to their latencies: (a) brainstem auditory evoked potentials occur within the first 10 ms, typically with 5–7 deflections, (b) middle-latency auditory-evoked potentials occur within 12 to 50 ms, and (c) long-latency auditory-evoked potentials range from about 50 to 250 ms with generators in the supratemporal auditory cortex. Steady-state auditory responses can be elicited by periodic stimuli, They can be used in frequency-tagging experiments, for example in following inputs from the left and right ear to the auditory cortices of both hemispheres.
