Neuroprosthetics for Auricular Muscles: Neural Networks and Clinical Aspects

Area of Science:

• Anatomy
• Neuroscience
• Biomedical Engineering

Background:

• Mammalian external ears contain extrinsic and intrinsic auricular muscles.
• These muscles have historically been considered vestigial in humans.
• Emerging wearable devices leverage auricular muscle neural networks for health monitoring and therapy.

Purpose of the Study:

• To detail the neural networks of extrinsic and intrinsic auricular muscles.
• To review current literature on the diagnostic and therapeutic applications of these muscles.
• To outline current and future neuroprosthetic uses of auricular muscles and their neural pathways.

Main Methods:

• Literature review of anatomical studies.
• Analysis of research on wearable biomedical devices.
• Exploration of neuroprosthetic applications and neural network utilization.

Main Results:

• Detailed mapping of extrinsic (posterior, superior, anterior) and intrinsic (helicis major/minor, tragicus, anti-tragicus, transverse, oblique) auricular muscle innervation.
• Identification of diagnostic and therapeutic potentials for wearable devices targeting neurological disorders, brainstem injuries, emotional states, and auditory functions.
• Overview of auricular muscles as bio-controllers for human neuroprosthetics.

Conclusions:

• Auricular muscles possess significant, previously underestimated, functional relevance.
• Their accessible location and neural networks make them ideal for advanced wearable biomedical devices.
• Further research into auricular muscle anatomy and function is essential for unlocking their full therapeutic and neuroprosthetic potential.
