Abstract The nuclear cyt-4 mutants of Neurospora crassa have been shown previously to be defective in splicing the group I intron in the mitochondrial large rRNA gene and in 3' end synthesis of the mitochondrial large rRNA. Here, Northern hybridization experiments show that the cyt-4-1 mutant has alterations in a number of mitochondrial RNA processing pathways, including those for cob, coI, coII and ATPase 6 mRNAs, as well as mitochondrial tRNAs. Defects in these pathways include inhibition of 5' and 3' end processing, accumulation of aberrant RNA species, and inhibition of splicing of both group I introns in the cob gene. The various defects in mitochondrial RNA synthesis in the cyt-4-1 mutant cannot be accounted for by deficiency of mitochondrial protein synthesis or energy metabolism, and they suggest that the cyt-4-1 mutant is defective in a component or components required for processing and/or turnover of a number of different mitochondrial RNAs. Defective splicing of the mitochondrial large rRNA intron in the cyt-4-1 mutant may be a secondary effect of failure to synthesize pre-rRNAs having the correct 3' end. However, a similar explanation cannot be invoked to account for defective splicing of the cob pre-mRNA introns, and the cyt-4-1 mutation may directly affect splicing of these introns.

Data-driven fMRI analysis techniques include independent component analysis (ICA) and different types of clustering in the temporal domain. Since each of these methods has its particular strengths, it is natural to look for an approach that unifies Kohonen's self-organizing map and ICA. This is given by the topographic independent component analysis. While achieved by a slight modification of the ICA model, it can be at the same time used to define a topographic order (clusters) between the components, and thus has the usual computational advantages associated with topographic maps. In this contribution, we can show that when applied to fMRI analysis it outperforms FastICA.
