Zhu et al. show that basal forebrain cholinergic neurons send fast, specific information about a broad range of sensory stimuli to the auditory cortex, modulated by slower fluctuations in cholinergic activity. These findings help us to understand how the cholinergic system multiplexes diverse representations to fulfil its multifaceted roles in attention, learning and memory.
