TAN
Tonically active neurons (TANs) are cholinergic interneurons (ChINs). They have mammalian analogues in the striatum. In our dataset, they have the largest somata, which are covered in spines and have large axonal arborizations. Due to their size, only a few TAN somata are included in the dataset, accounting for just 0.1% of adult neurons.
