    The aim of the thesis was to develop a model of an array of planar microelectrodes and to design an integrated curcuit to be used in the future system for simultaneous and independent stimulation and recording neuronal activity of hundreds cells. The first two chapters include discussion of neuronal cell operation and its interaction with a microelectrode, which enables to record the cell activity and to stimulate it electrically. Next, the microelectrode theory and results of impedance parametrization of the array are given. In chapter 4 the parameters of generated signals required for efficient and safe stimulation of alive tissue are discussed. In the following, the stimulation protocol leading to significant reduction the stimulation artifacts is proposed. In the last chapter the design of 64-channel integrated circuit for stimulation of neural cells and the results of its electrical tests are presented.
