چکیده

The frontal cortex (FC) is the seat of higher cognition. The genetic mechanisms that control formation of the functionally distinct subdivisions of the FC are unknown. Using a set of gene expression markers that distinguish subdivisions of the newborn mouse FC, we show that loss of Fgf17 selectively reduces the size of the dorsal FC whereas ventral/orbital FC appears normal. These changes are complemented by a rostral shift of sensory cortical areas. Thus, Fgf17 functions similar to Fgf8 in patterning the overall neocortical map but has a more selective role in regulating the properties of the dorsal but not ventral FC.

Morphological and functional midbrain phenotypes in Fibroblast Growth Factor 17 mutant mice detected by Mn-enhanced MRI

With increasing efforts to develop and utilize mouse models of a variety of neuro-developmental diseases, there is an urgent need for sensitive neuroimaging methods that enable in vivo analysis of subtle alterations in brain anatomy and function in mice. Previous studies have shown that the brains of Fibroblast Growth Factor 17 null mutants (Fgf17(-/-)) have anatomical abnormalities in the infe...

Uncontrolled stress produces severe defect in development of frontal cortex in the rat

One of the most important factors in drug addiction is stress. It has been shown that animals with prenatal stress history are more risky for drug dependence. It have also been shown that frontal cortex play a role in drug dependence. In the present study the effects of two kinds of mild stress during pregnancy on the development of frontal cortex in Wistar rats (250-300 g) were investigated. F...

Area Patterning of the Mammalian Cortex

Here we describe mechanisms regulating area patterning of developing mammalian neocortex, referred to as arealization. Current findings indicate an interplay between intrinsic genetic mechanisms and extrinsic information relayed to cortex by thalamocortical input. Intrinsic mechanisms are based on morphogens and signaling molecules secreted by patterning centers, positioned at the perimeter of ...
