Invariant selectivity of auditory neurons due to predictive coding
... We propose a dynamic Bayesian inference model and train it on a large database of natural speech to predict this invariant selectivity, i.e. predictive fields (PFs). The model can account for nonlinear contextual effects such as two-tone and forward suppression. The model neurons adapt rapidly to ne ...

Neurons These basic units of the nervous system intercommunicate electrochemically via synapses (junctions) between their projecting axons and dendrites – processes whose number and pattern divide neurons into three types: unipolar, bipolar, and multipolar. From unipolar or bipolar receptor neurons, ...
