+.. csv-table:: Estimates the mean spike rate across time and channels. Uses an exponentially weighted moving average to estimate a temporal mean (with adjustable time constant), and averages the rate across selected spike channels (electrodes). Outputs the resulting rate onto a selected continuous channel (overwriting its contents).

+Installing and upgrading
+###########################
+
+The Mean Spike Rate plugin is not included by default in the Open Ephys GUI. To install, use **ctrl-P** or **⌘P** to access the Plugin Installer, browse to the "Mean Spike Rate" plugin, and click the "Install" button.
+
+The Plugin Installer also allows you to upgrade to the latest version of this plugin, if it's already installed.
+
+
+Plugin configuration
+######################
+
+The plugin editor allows the user to set the following parameters:
+
+- **Active Spike Channels:** The spike channels to include in the mean spike rate calculation.
+
+- **Inactive Spike Channels:** The spike channels to exclude from the mean spike rate calculation.
+
+- **Output:** The continuous channel to output the mean spike rate onto. The mean spike rate will overwrite the contents of this channel.
+
+- **Time Constant** (ms): The time constant of the exponentially weighted moving average used to estimate the mean spike rate.
