Getting Started

Camber_tools for precision EMGThe purpose of this page is to provide guidance and resources for Myomatrix users. The examples of implantation protocols and other resources listed below come from procedures utilized in the Sober lab (at Emory University) and in collaborators' labs for recording single unit and bulk EMG from rodents, songbirds and primates. Note that CAMBER is unable to advise individual users on general surgical protocols (suturing, sterile technique) or basic electrophysiological methods (configuring or de-noising amplifiers and data-processing systems).

Select your Myomatrix array

  • Request a Consultation

    The CAMBER staff are available for discussing array designs that will best suit your experiments, for advising on surgical methods related to implanting the arrays, and/or for guiding data acquisition system choices. If you are a new Myomatrix user, we strongly suggest requesting a consultation. Consultations are ~30 minutes conversations over Zoom and can be scheduled using THIS LINK.

  • Consult the Myomatrix array catalog

    Myomatrix array designs and specifications can be found on the Array Catalog page.

  • Verify Myomatrix array sizing

    One can evaluate whether or not an array will reach the target muscle when the connector is mounted to the animal using this ARRAYS TO SCALE document.

  • Complete the Material Transfer Agreement

    The Material Transfer Agreement (MTA) sets up a legal agreement between the user's institution and Emory University and must be signed by the user and the institution's authorized signatory. The MTA must be completed prior to initial shipment of arrays.

  • Requesting Myomatrix Arrays

    Thanks to the generous funding from the NIH U24 program, CAMBER has distributed hundreds of arrays to the global neuroscience community at no cost to the user.  We will continue to accept orders for free arrays through November 30, 2025 and we will pause all requests in the month of December. Starting in January 2026, CAMBER will move to a payment model to ensure the sustainability of this resource.

    If you have a current MTA, you can still request arrays using THIS LINK until Nov. 30, 2025. 

  • Ordering Myomatrix arrays - Jan 2026

    To place an order with CAMBER, two critical steps need to be completed. First a new MTA detailing the array payment structure must be completed, even if you have a current MTA covering the no-cost transfer of arrays already in place. Second, purchasing arrays will required a purchase order (PO) and the details of setting up Emory-CAMBER as a vendor at your institution can be found on the Ordering Myomatrix Arrays tab. 

Using the Myomatrix Arrays

  • Equipment suggestions

    Consult the Tools and Hardware list  to ensure you have the appropriate equipment and electronics to use the Myomatrix arrays.

  • Impedance testing

    Testing impedance of the electrode contacts prior ot implantation is critical. READ more about why it is important and how to test impedance using either Intan Technologies or Open Ephys acquisition systems. Other data acquisition systems will have their own specific software for impedance testing.

  • Array implantation protocols

    These protocols describe typical array implantation procedures for acute recordings in Rhesus macaque biceps or for chronic recordings in mouse forelimb muscles.

  • Review surgical videos and protocols

    The CAMBER team has created videos demonstrating implantation of arrays in songbirds, mouse and non-human primates and sample IACUC protocols for array use in these species. Access to these materials is restricted to current Myomatrix array users. Email the CAMBER team at camber@emory.edu for access information.

  • Tips and Tricks

    Need some advice? Consult this document to obtain useful information about using the arrays, including which side of the array has the exposed electrode contacts, how to insert the ZIF clip interface, or which needle to use for the needle-injection arrays.

  • Analysis tools for Myomatrix array data

    Navigate to the Data Analysis page for a suite of tools designed to support users' analysis of data acquired using the Myomatrix arrays.
