The scanning electron microscope was used to examine the growth cones of sensory neurites on the basal lamina of the trunk skin and on the myotomes in dissected embryos of the amphibian, Xenopus laevis. On the myotomes growth cones are large and flat with extensive lamellipodia and many filopodia. On the skin growth cones are smaller and have simpler processes particularly in more ventral posit...

In this paper, we have studied the hydrogen adsorption onto CNCs and BNNCs nano-cones using GCMC simulations. The effects of length and cone apex angle on adsorption property have been investigated. Our results show that with increasing the pressure and decreasing the cone length and cone apex angle except for CNC-300˚, the hydrogen adsorption onto the BNNCs and CNCs was increased. It was also ...

The early zebrafish brain contains a simple axon scaffold of longitudinal tracts connected by commissures. Neurons in the nucleus of the posterior commissure (nuc PC) project growth cones along a specific route in this axonal scaffold, raising the possibility that specific axons in the early scaffold guide nuc PC growth cones. We tested this possibility by analyzing the behavior of nuc PC growt...
