DESCRIPTION

The optoelectrodes are fabricated on a GaN-on-silicon substrate with recording sites and precisely defined µLEDs (10 x 15 µm), allowing for simultaneous recording and local optogenetic stimulation with < 50µVpk-pk stimulation artifact. For chronic experiments, the N1-F21-O36/18 (right, below) features an extremely durable, yet flexible cable allowing for light-weight stereotactic head fixtures. For acute experiments, we recommend the N1-A0-O36/18 (left, below).

TYPICAL SYSTEM CONFIGURATION

For recording from the 32 electrodes, we recommend an Intan RHD2132 pre-amp headstage and an RHD2000 interface board. For stimulation, we recommend an open-source µLED driver system, OSC1Lite, which provides everything required for independent channel stimulation with custom waveform (software, battery, usb cable, Omnetics cable, etc). For stereotactic insertion, we recommend our 3D printable microdrive. The µLED driver system, 3D printable microdrive and an instructional surgery video can be found on the GitHub Microdrive.

APPLICATIONS
  • Optogenetic-control of local neural circuits in awake, behaving studies

  • Square-wave excitation for precise timing control

  • Sine-wave excitation for graded modulation

  • Chronic optogenetics where a microdrive is used for fine-tune positioning

MICRODRIVE
  • Optional for chronic use where position control is desired

  • Total travel –

    • Mouse – 2.6 mm
