New article in the Journal of Comparative Neurology
The article "Compartmental Localization of GABAB Receptors in the Cholinergic Circuitry of the Rabbit Retina," authored by Zucker, Nilson, Berndt Ehinger, and Grzywacz, has been published in this journal. The article reports the exciting finding that the dendritic trees of cholinergic amacrine cells are more complex than previously thought. The GABAB receptor appears in some but not all of the cell's varicosities. This inhomogeneity increases immensely the possibilities of cellular computations.
