Calcium and NeuroD2 control the development of thalamocortical communication.

ABSTRACT

Donald Hebb postulated the existence of a mechanism of activity-dependent transcription and synaptic modification almost 60 years ago. While the details of this process are still unclear, a new study by Ince-Dunn et al. in this issue of Neuron indicates that NeuroD2, a calcium-regulated transcription factor, plays a central role in thalamocortical synaptic maturation.
