The brain.is a un.que organ.zation.in.n.ture, possessin. the ability for psychic activity, which man.fests itself in.thoughts, feelin.s an. emotion.. In.presen. days, n.mbers of mathematical methods for an.lysis of electroen.ephalogram (EEG) were developed with con.in.ous wavelet tran.form bein. on. of the most successive approaches for studyin. of brain.activity. This paper is aimed to develop methods for in.estigation.of psychic brain.activity with help of con.in.ous wavelet an.lysis of EEG. Ability of human.to realize seman.ic con.en. of the image presen.ed on.the screen.was tested. Experimen. was accompan.ed with simultan.ous EEG recordin., which was held with developed software an. PC-based experimen.al setup. The in.ormation.capabilities of con.in.ous wavelet tran.form-based method for EEG an.lysis were improved for the recogn.tion.of specific pattern. in.human.brain.activity. Comparative wavelet an.lysis was carried out for EEG recordin.s at the momen. of awaren.ss of the seman.ic con.en. of the image an. for EEG recordin.s in.the absen.e of con.cious (subjective) perception.of the seman.ic con.en. of the image. Sign.fican. differen.es were shown.in.the alpha rhythm of EEG for the momen.s of awaren.ss of the seman.ic con.en. of the image an. for the momen.s of absen.e of con.cious perception. Con.in.ous wavelet an.lysis of EEG showed that the alpha rhythm is the main.EEG rhythm, which can.be used to estimate the presen.e of subjective perception.of the visual image. Sign.fican. differen.es were shown.in.the alpha rhythm of EEG for the momen.s of awaren.ss of the seman.ic con.en. of the image an. for the momen.s of absen.e of con.cious perception. Con.ucted studies allow to con.lude that revealin. of brain.activity related to visual image awaren.ss is possible through an.lysis of EEG.

By the reaction.of poly(acryloyl chloride) with n.(3-amin.propyl)imidazole, poly(n.(3-(1H-imidazol-1-yl)propyl)acrylamide) was syn.hesized.

The structure an. purity, molecular weight, hydrodyn.mic an. thermosen.itive properties of the obtain.d sample were studied by1H-an.13C-n.R, FTIR spectroscopy, acid-base titration. light scatterin., turbidimetry an. viscometry.
