Comprehensive structural and compositional analyses confirm phase\u2010pure crystallization, while impedance spectroscopy and localized current mapping images with the scanning tunneling spectroscopy (STS) reveal a filamentary switching mechanism precisely driven by reversible Ag\n                    <jats:sup>+<\/jats:sup>\n                    ion migration. Beyond non\u2010volatile memory, the devices successfully emulate essential synaptic behaviors, including excitatory postsynaptic current, paired\u2010pulse facilitation, and long\u2010term potentiation\/depression with tunable weight states, enabling robust plasticity. Notably, pattern recognition with trained spiking neural networks yields &gt; 95% accuracy on the MNIST dataset, surpassing practical application benchmarks. Furthermore, sequenced pulse training enables adaptive learning and associative memory, evidencing Pavlovian conditioning at the device level. This multifunctionality highlights CABB as a promising and eco\u2010friendly perovskite material that unites reliable resistive switching, neuromorphic learning, and cognitive adaptability, paving the way toward compact, energy\u2010efficient, and sustainable brain\u2010inspired hardware building blocks.\n
