"Electrical activity of biomembranes and vectorization of
We consider theoretical mechanisms of the
influence of intracellular electric fields on
directed polymerization and orientation of
microtubules. A generalization of Fromherz'
model of self-organization in the ionic channels
system of biomembranes is used for a simulation
of the interaction between the membrane electric
activity and the behaviour of submembrane
cytoskeletal components. A similar interaction
between the membrane electric activity and
directed polymerization of microtubules can also
play a fundamental role in neuronal mechanisms
of learning and memory.

"The Change of Initial Symmetry in the Pattern-Form
Interaction Model of Sea Urchin Gastrulation"
Alexander V. Spirov
The characteristic feature of pattern-form
interaction models is feedback loop from
biochemical pattern formation to form changes in
the developing embryo. The models are directed
towards prediction of changes of the embryo
surface geometry and biochemical pattern. We
deal with an investigation of the mechanisms of
"amplification" of non-linear response of a
morphogens reaction-diffusion system due to
changes of geometry in the developing object.
Potentiality of approach is demonstrated by
simulation of gastrulation and the following
morphogenesis of the sea urchin embryo.
