• To introduce accompanying open-source software for efficient data analysis and neuronal characterization.

Main Methods:

• Development of an automated high-throughput robotic patch-clamp system.
• Streamlined protocol for neuron dissociation, patch-clamp experiments, and data analysis.
• Utilizing open-source software with a graphical user interface for biophysical equation fitting.

Main Results:

• Enables simultaneous and unbiased analysis of neurons in their native state.
• Provides a protocol for streamlined procedures from cell preparation to data analysis.
• The methodology is applicable to diverse research areas, including drug development.

Conclusions:

• This automated patch-clamp approach significantly enhances throughput for neuronal analysis.
• The integrated protocol and software facilitate functional characterization of individual neurons.
