From: Cortical ensemble activity discriminates auditory attentional states
Activity of the auditory cortical neuron population distinguishes different attentional states. a A plot of population activity of stimulus-responsive neurons immediately after stimuli onset in different attentional states (20 trials for each state). Dots represent individual trials and are plotted in the same dimensionality-reduced space. b & c Decoder performance of the stimulus-responsive population (b) or entire recorded population (c) in distinguishing two attentional states after stimuli onset: attended versus passive (red, p = 5.14 × 10− 4 in b, p = 6.90 × 10− 7 in c), ignored versus passive (blue, p = 4.33 × 10− 4, p = 8.41 × 10− 7), ignored versus attended (purple, p = 1.9 × 10− 3, p = 1.50 × 10− 5). Colored circles are from experimental data, and grey circles are from shuffled data. Statistical analyses were performed in a paired-sample t test between experimental and shuffled data (n = 12). All data represent the mean ± SEM. d Comparisons of decoder performance between the stimulus-responsive population and the entire population after stimuli onset. (attended versus passive, red, p = 3.10 × 10− 4; ignored versus passive, blue, p = 7.75 × 10− 4; ignored versus attended, purple, p = 7.20 × 10− 4; paired-sample t test, n = 12). e Decoder performance of the stimulus-nonresponsive population in distinguishing two attentional states after the cue onset: attended versus passive (red, p = 4.68 × 10− 7), ignored versus passive (blue, p = 5.08 × 10− 7), ignored versus attended (purple, p = 1.43 × 10− 5). Colored circles are from experimental data, and grey circles are from shuffled data. Statistical analyses were performed in a paired-sample t test between experimental data and shuffled data (n = 12). Data are presented as mean ± SEM
