Effects of Transcranial Electrical Stimulation on Human Auditory Processing and Behavior-A Review

Area of Science:

• Neuroscience
• Auditory Neuroscience
• Cognitive Neuroscience

Background:

• Transcranial electrical stimulation (tES) non-invasively alters neural activity by applying weak currents to the scalp.
• tES has emerged as a valuable tool for investigating neural processes underlying human behavior.
• Research on tES applications in hearing and its electrophysiological effects remains limited.

Purpose of the Study:

• To review the neuromodulatory effects of tES on auditory processing.
• To explore the impact of tES on auditory-related behavior and cognitive functions.
• To summarize the physiological effects of tES specifically on the auditory cortex.

Main Methods:

• Literature review of studies investigating tES and auditory processing.
• Analysis of behavioral and electrophysiological data from tES research.
• Synthesis of findings on tES-induced changes in auditory cortex function.

Main Results:

• tES can modulate neural activity in the auditory cortex.
• Evidence suggests tES influences auditory perception, including localization and pattern recognition.
• The review consolidates current understanding of tES's physiological impact on auditory functions.

Conclusions:

• tES shows promise as a tool for studying and potentially modulating auditory processing.
• Further research is needed to fully elucidate the mechanisms and applications of tES in hearing science.
• This review provides a foundation for future investigations into tES for auditory and cognitive enhancement.
