Regulation of inflammatory responses by dynamic subcellular localization of RNA-binding protein Arid5a.

abstract：:Intrinsic horizontal axon collaterals in the striate cortex of adult cats specifically link columns having the same preferred orientation; consequently, retrograde tracer injections result in intrinsic labeling that is sharply clustered.
