Thalamus is a critical information relay hub in the cortex; its malfunction causes multiple neurological and psychiatric disorders. However, there are no model systems to study the development and function of human thalamus. Here, we present a protocol to generate regionally specified human brain organoids that recapitulate the development of the thalamus using human pluripotent stem cells (hPSCs). Thalamic organoids can be used to study human thalamus development, to model related diseases, and to discover potential therapeutics. For complete information on human thalamic organoids and their application, please refer to the paper by Xiang et al. (2019).
