Serial attentional resource allocation during parallel feature value tracking.

The visual system has evolved the ability to track features like color and orientation in parallel. This property aligns with the specialization of processing these feature dimensions in the visual cortex. But what if we ask to track changing feature-values within the same feature dimension? Parallel tracking would then have to share the same cortical representation, which would set strong limitations on tracking performance.

T-weighted in vivo human whole brain MRI dataset with an ultrahigh isotropic resolution of 250 μm.

We present an ultrahigh resolution in vivo human brain magnetic resonance imaging (MRI) dataset. It consists of T-weighted whole brain anatomical data acquired at 7 Tesla with a nominal isotropic resolution of 250 μm of a single young healthy Caucasian subject and was recorded using prospective motion correction. The raw data amounts to approximately 1.

Caldendrins in the inner retina.

Caldendrin is the first member of a novel family of Ca2+-binding proteins (CaBPs). Its unique two-domain structure is composed of a calmodulin-homologous teminus and an unrelated N-terminal part. The latter is thought to mediate the tight association of caldendrin with the subsynaptic cytoskeleton.

Transcripts for secreted and GPI-anchored brevican are differentially distributed in rat brain.

Brevican is a member of the aggrecan/versican family of proteoglycans. In contrast to the other family members, brevican occurs both as soluble isoforms secreted into the extracellular space and membrane-bound isoforms which are anchored to the cell surface via a glycosylphosphatidylinositol (GPI) moiety. Expression of both variants, which are encoded by two differentially processed transcripts from the same gene, is confined to the nervous system.
