Abstract

Causal inference serves as a fundamental cortical function that inherently involves neural communication across various cortical areas. However, the computational principles through which neurons communicate with each other to implement causal inference remain unclear. To address this question, this paper presents a two-layer spiking neural network under the hidden Markov model (HMM) framework to investigate basic visual causal inference. A hidden cause determines whether directions of paired visual stimuli share a common source, randomly. Receiving stimuli, the network incorporates neural communication to generate random responses and employs a distance-based method to infer the hidden cause. With rewards from inference, the network updates its parameters during training. The trained network achieves acceptable performance in designed visual causal inference while reproducing key neurodynamic phenomena of sparse coding and neural variability quenching. The spiking neural network integrates neural communication into an HMM-based unified framework for sparse coding, neural variability quenching, and visual causal inference.
