Biologists found out a parentage of cells candelabrums

The American scientists from laboratory Kold Spring Harbor established a clonal parentage of cells candelabrums, the neurones of a cerebral cortex uniting to information from hundred "usual" neurones. Cells candelabrums were open about 40 years ago. Their difference from usual neurones consists that they form contacts to many pyramidal cells. Because of a set of contacts which are visible at a staining, cells candelabrums and received the name. One of pioneers of structure of DNA, Frensis Krik, put forward cells candelabrums on a role of integrators which control "simple" neurones of a cortex and if necessary "impose the veto" on exaltation diffusion between them. Nevertheless, it was till today unclear, these neurones are how formed. Authors of new research showed that these cells are formed of earlier unknown zone of a fetal brain (a ventral germinal zone - VGZ). Also scientific it was possible to find out, what gene specifically is responsible for their development.

To track "destiny" of cells it was possible thanks to specific synthesis of fluorescent proteins and the subsequent analysis of sections. Scientists notice that their research is of great importance for comprehension of how interaction between neurones from the point of view of hierarchy and spatial structure is organized. While on this subject neurobiologists know a little that is bound to extreme complexity of "disentangling" of structure of contacts of neurones. Let's remind, earlier Chinese scientists studied the impulses going from a human brain, and transformed them to musical waves. As a result researchers came to a conclusion that music of reason is similar to the jazz.
