BACKGROUND The rapid adaptation of actions to changes in the environment is crucial for survival. We previously demonstrated a joint contribution of left dorsal premotor cortex (PMd) and left supramarginal gyrus (SMG) to action reprogramming. However, we did not probe the contribution of PMd to the speed and accuracy of action reprogramming and how the functional relevance of PMd changes in the...

P elizaeus-Merzbacher disease (PMD, MIM 312080) is an X linked disorder characterised by dysmyelination of the central nervous system (CNS) 2 (see review by Koeppen and Robitaille). Two main forms of the disease, a connatal and a classical type, are recognised. The connatal type has a severe course with feeding problems, progressive pyramidal and extrapyramidal symptoms, laryngeal stridor, micr...

Pelizaeus Merzbacher's Disease is an inherited X-linked recessive trait. Males have the disease, while females are usually carriers. We report the case of a 6-years-old girl who had nystagmus since birth and later on developed head nodding. She started talking at one year and walking at 18 months. Then she developed regression of milestones, with speech impairment and inability to walk which pr...

Genomic architecture, higher order structural features of the human genome, can provide molecular substrates for recurrent sub-microscopic chromosomal rearrangements, or may result in genomic instability by forming structures susceptible to DNA double-strand breaks. Pelizaeus-Merzbacher disease (PMD) is a genomic disorder most commonly arising from genomic duplications of the dosage-sensitive p...

Disease-causing mutations in genes encoding membrane proteins may lead to the production of aberrant polypeptides that accumulate in the endoplasmic reticulum (ER). These mutant proteins have detrimental conformational changes or misfolding events, which result in the triggering of the unfolded protein response (UPR). UPR is a cellular pathway that reduces ER stress by generally inhibiting tran...
