Focal epilepsies in young patients are frequently associated with differentiated glioneuronal tumours. Dysplastic neurones represent a characteristic neuropathological feature of gangliogliomas, the most common entity encountered in this group. Here, we have analysed two major components of the reelin pathway involved in neuronal migration and cortical(More)
We present a model for unicellular algal growth as motivated by several experiments implicating the importance of calcium ions and " loosening " enzymes in morphogenesis. A growing cell at rest in a diffusive calcium solution is viewed as an elastic shell on short timescales. For a given turgor pressure, we calculate the stressed shapes of the wall elements(More)
