[A modified device for transcutaneous electrical auricular concha stimulation in rats].

Area of Science:

• Neuroscience
• Biomedical Engineering
• Animal Models

Background:

• Auricular stimulation is a non-invasive technique used in research.
• Existing methods for auricular stimulation in rats can be cumbersome and prone to issues.
• There is a need for improved devices for consistent and reliable auricular stimulation in rodent models.

Purpose of the Study:

• To introduce a novel transcutaneous electrical auricular concha stimulator (TEACS) for rats.
• To present a modified output electrode design for enhanced usability and durability.
• To address limitations associated with previous auricular stimulation devices.

Main Methods:

• Development of a new device: transcutaneous electrical auricular concha stimulator (TEACS).
• Design of specific output electrodes utilizing magnets for secure attachment to the auricular concha and dorsal auricle.
• Connection of electrodes to a main unit via wires, replacing traditional spring clips.

Main Results:

• The TEACS device incorporates a main unit with power and control buttons.
• The newly designed magnetic output electrodes ensure firm attachment, preventing loosening.
• The modified electrodes are more durable and less prone to injury compared to original spring clips.
• The device demonstrates simplicity, flexibility, and convenience in application.

Conclusions:

• The transcutaneous electrical auricular concha stimulator (TEACS) offers a significant improvement over existing methods.
• The magnetic electrode design enhances the reliability and ease of auricular stimulation in rats.
• This new device is well-suited for various research applications requiring precise and stable auricular stimulation in rodent models.
