In the initial published version of this article, there was an error in the “MATERIALS AND METHODS” section. The catalog number of PEGMMA500 for preparing tB-PEG dehydration solution and BB-PEG clearing medium was listed as Sigma-Aldrich 409529. The correct catalog number should be Sigma-Aldrich 447943. The catalogue number for the same chemical provided in the Supplementary data S1 is correct. This correction does not affect the description of the results or the conclusions of this work.
