  1. Leptin excites enteric neurons of guinea-pig submucous and myenteric plexus Volume 23, Issue 4, e165–e170, Article first published online: 12 January 2011

In [1] the leptin concentration was miscalculated. Throughout the manuscript the leptin concentration should read 62.5 nmol L−1 instead of 0.0625 nmol L−1.

There are accompanying amendments in the text as a result of this change which are as follows:

Discussion, Page e168, on column 2, line 45 should read: “The concentration we used is in the range that has been reported to activate pro-opiomelanocortin neurons in the brain. 2(20 in the original paper)” instead of “It needs to be emphasized that the concentration we used is 100 times less than the EC50 to activate pro-opiomelanocortin neurons in the brain. 2

We deeply regret this error and apologize for the confusion this may have caused.
