Basal forebrain cholinergic neurons (BFCN) modulate synaptic plasticity, cortical processing, brain states and oscillations. However, whether distinct types of BFCN support different functions remains unclear. Therefore, we recorded BFCN in vivo, to examine their behavioral functions, and in vitro, to study their intrinsic properties. We identified two distinct types of BFCN that differ in their firing modes, synchronization properties and behavioral correlates. Bursting cholinergic neurons (BFCNBURST) fired synchronously, phase-locked to cortical theta activity and fired precisely timed bursts after reward and punishment. Regular firing cholinergic neurons (BFCNREG) were found predominantly in the posterior basal forebrain, displayed strong theta rhythmicity and responded with precise single spikes after behavioral outcomes. In an auditory detection task, synchronization of BFCNBURST to auditory cortex predicted the timing of mouse responses, whereas tone-evoked cortical coupling of BFCNREG predicted correct detections. We propose that the balance of two basal forebrain cholinergic neuron types generates behavior-specific cortical activation.
