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.
  • Ordering Myomatrix Arrays

    One can request the Myomatrix arrays by filling out THIS FORM.

    As of February 2025, we are still distributing the array devices for free to the global neuroscience community, thanks to support from the NIH Brain Initiative. As per the NIH guidelines,  we will transition to a pay model for the devices and will be announcing the pricing structure and the timing of the transition to a purchase model to the CAMBER community in the coming weeks.

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.
  • 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.
