Single-cell atlas of thalamic projection systems

We collected single-cell RNAseq data from neurons of five thalamocortical projection systems (motor, somatosensory, visual, auditory, and prefrontal). Cells of each projection system were retrogradely labeled from their cortical target area, microdissected, and collected individually. By combining single-cell transcriptomics with in situ RNA hybridization, we found heterogeneity not only between thalamic nuclei but also within nuclei, with graded transitions between cell identities.
