Ongoing neural activity unfolds over intrinsic timescales that vary widely across the brain. The increase in timescales along the sensory-transmodal cortical axis parallels the cortical hierarchy, while diversity of timescales within each area may reflect functional specialization of individual neurons. However, mechanisms that give rise to the diversity of timescales within and across brain areas remain largely unknown. We leveraged a brain-wide dataset of single-neuron activity to characterize the intrinsic timescales across the whole mouse brain. Timescales varied widely across brain region
