Cowan Award

Pasko Rakic

The 2013 Cowan Award was presented to Dr. Pasko Rakic, in recognition of his outstanding contributions to developmental neuroscience as well as his continued support of the Journal of Comparative Neurology. Dr. Rakic received his MD in 1959 from the University of Belgrade, at the time in Yugoslavia, followed by graduate training at the same institution in developmental biology and genetics culminating in his PhD degree in 1969. He also entered residency training in neurosurgery and in 1969 moved to the USA to join the Department of Neurosurgery at Harvard University. He soon however was inspired to pursue his interests in basic neuroscience and moved to the Department of Neuroscience at Harvard. He was recruited in 1978 to Yale School of Medicine by Nobel laureate George F. Palade, as the first chair of the Department of Neurobiology, a position he still holds today as the Dorys McConnell Duberg Professor of Neuroscience. He is also Professor of Neurology and Director of the Yale Kavli Institute for Neuroscience. In 1985, Dr Rakic was elected to the National Academy of Sciences of the USA. He became a foreign member of the Serbian Academy of Sciences and Arts, and in 1990, a correspondent member of Croatian Academy of Sciences and Arts. He is a member of the American Academy of Arts and Sciences and served as President of the Society for Neuroscience in 1995-96. In 1997, he received a Doctor honoris causa from the University of Zagreb, Croatia. He is also a member of the Norwegian Academy of Science and Letters. Dr Rakic has been over the years a strong supporter of the Journal of Comparative Neurology, for which he serves as a member of the Editorial Board. He is also the Editor-in-Chief of Cerebral Cortex, the journal he founded in 1990 with his wife, the late Patricia Goldman-Rakic. Dr Rakic made immense contributions to developmental and evolutionary neuroscience that changed the way we understand how the cerebral cortex develops. Most notably, two of his hypotheses had a particular impact on the field. The first is the radial unit hypothesis, which posits that in the developing cerebral cortex the cells are created at the base of radial columns, each new cell migrating past its predecessors. The second, the related protomap hypothesis, explored how external signals determine cell function as the cell matures and forms complex connections. This work was recognized in 2003 when he received the Annual Bristol-Meyers Squibb Award for Distinguished Achievement in Neuroscience Research and in 2008, with Drs Thomas Jessell and Sten Grillner, of the first Kavli Prize for Neuroscience.

Groundbreaking Studies Hypothesize Toward a Unifying Formulation of the Organization of Vertebrate Forebrain

Pallium Editorial Figure 1

A most exciting aspect of several recent studies on the comparative biology of the telencephalon is that neurobiologists may be on the verge of providing a unifying formulation of the organization of the forebrain of all vertebrates. JCN is proud to feature a pair of groundbreaking companion articles "A global view of the functional molecular organization of the avian cerebrum: Mirror images and functional columns" and "Molecular profiling of the developing avian telencephalon: regional timing and brain subdivision continuities" on the avian telencephalon that hypothesize that the mesopallium and adjoining divisions of the hyperpallium have a common developmental origin. The studies demonstrate that these structures initially exhibit common gene expression domains but with subsequent development, fold to form mirror images within subdivisions of the dorsal and ventral pallium. The expression profile in each subdivision has a different temporal order of appearance, similar in timing to analogous cell types of the mammalian cortex. Further, as in the mammalian pallium, expression patterns in the avian ventral pallial subdivisions become distinct during pre-hatch development, whereas expression in the dorsal portions does so during later, post-hatch development. These findings support the continuum hypothesis of avian brain subdivision development around the ventricle and potentially reinforce hypotheses on pallial homologies between birds and other vertebrates.

An Important Landmark in Scientific Publishing

Retinorecipient areas in the diurnal murine rodentIn their recent article, Gaillard, Karten and Sauvé have set an important scientific milestone by placing their entire experimental image collection for this study on a publicly accessible server located here, making it available to anyone with an internet connection at the highest native scan resolution (0.5 µm/pixel). This unprecedented level of access to all histologic supporting data implements a completeness that we believe will result in more informed peer review, a finer granularity of interpretation at the reader level, the promotion of related research, and longevity of original image data. We would like to thank the authors and MBF Bioscience for collaborating on this meaningful contribution, which we hope will encourage the neuroscience community at large to extend such completeness and openness to the readers of their own published work.
