Fig. 2: Firing rates of working memory-active neurons and non-active neurons in the spatial task.
From: Unraveling the roles of spatial working memory sustained and selective neurons in prefrontal cortex

The mean firing rate was averaged across spatial stimuli for neurons classified as A) WM-sustained neurons and B) WM-selective neurons, based on firing rates in the first delay and second delay periods. n = 233, n = 191, n = 449 neurons for the first delay WM-sustained, the second delay WM-sustained, and the not sustained neurons, respectively. n = 120, n = 124, n = 507 neurons for the first delay WM-selective, the second delay WM-selective, and the not selective neurons, respectively. Data are represented as mean ± SEM.
