Background:

Understanding neural networks in vitro is crucial for deciphering complex brain functions.
Existing methods for patterning neurons often restrict cell morphology and network connectivity.

Purpose of the Study:

To develop a versatile platform for creating high-density, topologically defined neural networks in vitro.
To enable single-cell resolution interrogation of neural circuitry and network dynamics.

Main Methods:

A novel sacrificial-layer-protected PDMS molding method was used to fabricate the NeuroArray device with through-structures.
The NeuroArray technique patterns primary neurons in array formats, accommodating neurite outgrowth.
Calcium imaging was employed for large-scale tracking and recording of neuronal activity.

Main Results:

Successfully created well-connected, spontaneously active neural networks with designed topologies.
Characterized spiking dynamics and transmission within a diode-like neural network.
Demonstrated the platform's capability for large-scale neuronal activity recording.

Conclusions:

NeuroArray is an effective platform for in vitro neural network recreation, supporting complex network formation and analysis.
The platform is adaptable for various applications, including high-throughput drug testing and building neuron-based computational devices.
