Tonic disinhibition of left motor cortex during prism adaptation enhanced consolidation of sensorimotor and cognitive prism after effects, causing lasting clinical gains in three patient cases with chronic treatment-resistant visual neglect.
Electrically active axons in white matter stimulate their own myelination by releasing glutamate, which signals through AMPA-type glutamate receptors on nearby oligodendrocyte precursors and newly-differentiating oligodendrocytes, enhancing their survival and hence their ability to myelinate.
A rigorous and transparent evaluation of mesenchymal stem cell therapy for sepsis suggests it may be efficacious, although the strength of these findings is tempered by threats to validity in the studies that were included.
Protein coding genes strongly support a sister group relationship between Placozoa and Cnidaria to the exclusion of Bilateria, contradicting previous phylogenies, which have likely been misled by pervasive compositional heterogeneity.
The enzyme PKMzeta is crucial for the maintenance of long-term memories, but a closely related enzyme provides a back-up should PKMzeta fail, thus explaining the controversy over why deleting the gene for PKMzeta may not appear to impair memory.
