Background:

• Multiple patch-clamp recordings and morphological reconstruction are essential for studying neuronal microcircuitry.
• These techniques require specialized expertise, posing a challenge for researchers.

Purpose of the Study:

• To present a standardized protocol for applying multiple patch-clamp recordings and morphological reconstruction to mouse medial entorhinal cortex (MEC) neurons.
• To facilitate neuronal microcircuitry dissection and cell type classification in the MEC.

Main Methods:

• Detailed protocol for preparing brain slices containing the MEC.
• Simultaneous multiple whole-cell recordings from MEC neurons.
• Histological staining and subsequent neuronal reconstruction.
• Analysis of combined morphological and electrophysiological data.

Main Results:

• Successful application of the protocol to mouse MEC neurons.
• Generation of comprehensive datasets combining electrophysiological and morphological features.
• Demonstration of the protocol's utility for detailed neuronal analysis.

Conclusions:

• The presented protocol simplifies complex electrophysiological and morphological analyses of MEC neurons.
• This method enhances the ability to classify cell types and dissect microcircuitry within the MEC.
• The protocol serves as a valuable resource for neuroscience research.
