[Energy transformation in mechanoreceptors].

The values of relative threshold deformations and of the mechanosensitivity coefficent are evaluated for some mechanoreceptors. The thermodynamical model of energy transformation in a primary act of mechanoreception is presented, the values of mechanical elastic energy stored in the membrane are calculated. The model of the mechanosensitive center as the ion-selective channel, changing dimensions of its protein part due to closing and opening of the channel is shown to give satisfactory values of the free energy change of the system at the threshold stimulus.
