A Percentage of responsive neurons to visual stimuli in each class. These neurons exhibit a significant increase in firing rate during the stimulus presentation period compared to baseline. Pre-training recordings for each class are depicted in light colors, while post-training units are depicted in dark colors. In the pre-training phase, 27.4% (n = 23/84), 30.8% (n = 84/273), 23.1% (n = 124/536), and 25.7% (n = 100/389) of NS1, NS2, BS1, and BS2 neurons were responsive, respectively. In the post-training phase, the percentages were 46.2% (n = 30/65), 39.2% (n = 114/291), 36.4% (n = 209/574), and 24.6% (n = 61/248) for NS1, NS2, BS1, and BS2 neurons, respectively. B Percentage of responsive neurons during the delay period in each class. These neurons exhibit a significant increase in firing rate during the delay period compared to baseline. In the pre-training phase, 25.0% (n = 21/84), 20.2% (n = 55/273), 16.2% (n = 87/536), and 17.5% (n = 68/389) of NS1, NS2, BS1, and BS2 neurons were responsive, respectively. In the post-training phase, the percentages were 38.5% (n = 25/65), 35.7% (n = 104/291), 35.4% (n = 203/574), and 27.4% (n = 68/248), respectively. C Total percentage of responsive neurons during either the stimulus presentation or delay period (or both) in each class. These neurons exhibit a significant increase in firing rate during either or both periods compared to baseline. In the pre-training phase, 41.7% (n = 35/84), 37.0% (n = 101/273), 31.0% (n = 166/536), and 31.6% (n = 123/389) of NS1, NS2, BS1, and BS2 neurons were responsive, respectively. In the post-training phase, the percentages were 55.4% (n = 36/65), 50.2% (n = 146/291), 49.0% (n = 281/574), and 39.1% (n = 97/248), respectively. D Changes in the percentage of responsive units during the stimulus presentation period after training and execution of the WM tasks for each class. E Changes in the percentage of responsive units during the delay period after training and execution of the WM tasks for each class. F Changes in the total percentage of responsive units during either the stimulus presentation or delay period (or both) after training and execution of the WM tasks for each class.
