The inhibitory neurons of the thalamic reticular nucleus are produced by the rostral progenitor domain of the embryonic diencephalon.

During development, the thalamus is divided into two distinct progenitor domains: the caudal domain and the rostral domain. While the caudal domain gives rise to excitatory glutamatergic neurons that form the primary thalamic nuclei, the rostral domain is responsible for the development of the inhibitory GABAergic neurons that constitute the reticular nucleus.1
