Values of the 2 offers modulate firing rates of individual dACC neurons.

<p><b>(A)</b> Firing rate of 1 example neuron significantly modulated by the expected value of the first offer both when it was being presented (multiple linear regression: β = 0.041, <i>p</i> = 0.011) and when it was remembered (β = 0.051, <i>p</i> = 0.0097). <b>(B)</b> Example dACC neuron activity, significantly modulated by the value of the second offer while it was being presented (β = 0.046, <i>p</i> = 0.0061). <b>(C)</b> Percentage of neurons significantly tuned to the value of the first (red) and second (blue) offers through the course of the trial, using a multiple linear regression with a sliding 500-ms window. <i>Data used to generate these plots can be found at <a href="https://doi.org/10.5061/dryad.h52f8" target="_blank">https://doi.org/10.5061/dryad.h52f8</a></i>. dACC, dorsal anterior cingulate cortex; EV, expected value of gamble.
