INT3
This cell type is one of three newly described interneuron types in the dataset. Due to its dense axonal arborisations and regular boutons, its morphology is similar to that of the fast-spiking interneuron type found in the mammalian striatum. However, closer analysis revealed morphological and connectivity differences between the three types. Of these, INT3 has the largest soma and the longest axons. Additionally, half of the neurons form autapses, accounting for 0.8% of adult neurons.
