Abstract     Recently, experiments have drawn attention to thin anisotropic structures of the bilayer membranes in cells and phospholipid vesicles. Such structures are nano and microtubes, torocytes and toroidal edges of the membrane pores. The stability of these structures cannot be explained ifthe membrane is treated as an isotropic, laterally homogeneous two dimensional liquid Apossible explanation is however given by considering the deviations in elasticity that is the consequence of the orientational ordering of the anisotropic membrane constituents. In this work we present experimental evidence for phospholipid micro and nanotubes and the hypothesis proposing that thin anisotropic structures of the membrane compose an important pool of the membrane material that we call the subjacent pool of the membrane materiak It seems that the nanotube connections within the cell form the infrastructure for directed transport of the information and material Therefore the subjacent pool may be viewed as a contribution to information transfer/cognition on the cellular level.
