-3. **MED** - Automatically sets the threshold based on a multiple of the median value of each channel. This method is more robust to outliers (like very large-amplitude spikes) than the STD method. See `Quian Quiroga et al. <https://pubmed.ncbi.nlm.nih.gov/15228749/>`__ for more details.

 To change the thresholding algorithm for multiple (or all) electrodes at once, use the **#** column (or Ctrl/⌘-A) to select multiple electrodes. Then, any changes to once electrode's threshold settings will propagate to all other selected electrodes.
