Defines a configuration for single-shank, Neuropixels 2.0 and 2.0-beta probes.
Properties
| Property | Type | Description |
|---|---|---|
Reference
|
Enum |
Gets or sets the reference for all electrodes. The available references for a single-shank probe are NeuropixelsV2SingleShankReference. |
InvertPolarity
|
bool |
Gets or sets a value determining if the polarity of the electrode voltages acquired by the probe should be inverted. Neuropixels contain inverting amplifiers. This means that neural data that is captured by the probe will be inverted compared to the physical signal that occurs at the electrode: e.g., extracellular action potentials will tend to have positive deflections instead of negative. Setting this property to true will apply a gain of -1 to undo this effect. |
GainCalibrationFileName
|
string |
Gets or sets the path to the gain calibration file. Each probe is linked to a gain calibration file that contains gain adjustments determined by IMEC during factory testing. Electrode voltages are scaled using these values to ensure they can be accurately compared across probes. Therefore, using the correct gain calibration file is mandatory to create standardized recordings. Calibration files are probe-specific and not interchangeable across probes. Calibration files must contain the serial number of the corresponding probe on their first line of text. If you have lost track of a calibration file for your probe, email IMEC at neuropixels.info@imec.be with the probe serial number to retrieve a new copy. |
ProbeInterfaceFileName
|
string |
Gets or sets the file path where the ProbeInterface configuration will be saved. |
