Erratum to: Brain Struct Funct DOI 10.1007/s00429-015-1000-4

Unfortunately, there is a typographical error in the original publication. The name of the designer drug throughout the article should be (DREADD) hM4Di and not hM3Di.

It is important not to assume a double error since hM3Dq is an excitatory receptor while hM4Di, which has been used is inhibitory as stated in the paper. There is no designer drug named hM3Di.
