ThetaStation is an opto-mechanical tool designed to perform spatial selective light delivery with OptogeniX Lambda fibers.
ThetaStation allows to confine and manually scan the light emitted by a Lambda fiber at sub-sites of its active length. By doing so, sub-portion of the tissue region where the Lambda fiber is implanted can be independently probed: this capability gives access to an additional degree of freedom during optogenetics experiments, which has particular relevance when readout techniques extending along one axis are used simultaneously with the site-selective light delivery (e.g. linear microelectrode array).
- Laser sources are recommended for the use of ThetaStation.
- Use a Single Mode (SM) input patch cord for best transmission efficiency.
- Position and size of light emitting sub-regions of Lambda fibers, and transmission efficiency need to be calibrated as a function of the micrometer screw position.
