Summary (AI generated)

On the right, you can see the results comparing the simulation of software to the hardware implementation in Bioeum. It is evident that the behavior is exactly the same. We emulated for 150 milliseconds and monitored the results. The data can be accessed on another PC or saved to an SD card if desired. Different representations were also made for various dimensions depending on the segment, showing the propagation of the action potential throughout the network. All of this was compared to the software neuron, yielding identical results.
