One thought on “Friday Paper Post – Dec. 20th

  1. With regard to the first paper in the list by Kohara et al.: This is a very interesting paper, although the authors’ claim that they have corrected previous claims of predominant entorhinal layer III projections to the hippocampal CA2 area is in error. In fact, they have confirmed our recent study showing that it is layer II that predominantly projects to the CA2 region. The authors mistakenly say that we (their ref. 19=Cui et al., J Comp Neurol 521:1844-66, 2013) found layer III projections, when we clearly state “our tracer results revealed that most of the cortical input to CA2 originates in layer II of the ipsilateral medial and lateral entorhinal cortices (MEC, LEC, respectively) … Fewer, less intensely labeled neurons in layer III were labeled” (page 1847; Fig. 2).

    We hope that the authors will see fit to print an erratum.
