Fig. 3.

Behavioral experiment controller based on the Arduino Nano board (A) and custom schematics on a breadboard enclosed in a box (Figure created with Fritzing software). The controller is connected to multiple electronic components of the behavioral box – automatic feeder (B) and floor bar sensors (C) with the use of a 10pin connector (A), which makes the assembly-disassembly of the box easy (D). The schematics are also provided separately on the Supplementary figure 4 and in the GitHub repository.
