Before revision:  Here, we employ such methods to investigate the characteristics of neurons recorded by multielectrode arrays in the cortex of human and monkey throughout states of wakefulness and sleep . Taking advantage of the separation of cells into excitatory and inhibitory  types, we construct a model including this biological feature. By comparing the performances of Maximum Entropy models at predicting neural activity in wakefulness and deep sleep, we identify the dominant interactions between neurons in each brain state.
After revision:  Here, we employ such methods to investigate the characteristics of neurons recorded by multielectrode arrays in the cortex of human and monkey throughout states of wakefulness and sleep . Taking advantage of the separation of cells into excitatory and inhibitory types, we construct a model including this distinction. This approach allows to shed light upon differences between excitatory and inhibitory activity across different brain states such as wakefulness and deep sleep, we identify the dominant interactions between neurons in each brain state.
