Cortical Plasticity as a Mechanism for Storing Bayesian Priors in Sensory Perception

Figure 2

Neuronal population activity and derived log-likelihood functions.

Left panels show population activity of the model 7-kHz-over-represented AI, and the right panels show stimulus log-likelihood functions. (a) Response of the model to a 4-kHz tone pip (b) Elevated baseline activity in the absence of a stimulus (c) Summed spontaneous and 4-kHz-evoked activity). Each bar in the left panels represents the firing rate of a model neuron. The neurons are arranged by characteristic frequency, with low frequency-tuned neurons on the left and high frequency-tuned neurons on the right. Blue dotted lines in the right panels show the input frequency, red dotted lines show the over-represented frequency, and the black dotted lines mark the peaks of the log-likelihood functions.
