We also demonstrate chemical control of synaptic plasticity via solvent vapor exposure. This biomimetic neuromodulation tunes transport and learning rules based on vapor polarity, proticity, and steric effects. This work establishes conductivity modulation as an important design metric for MPECs and highlights their potential as designable platforms for stimuli\u2010responsive applications.\n
