Electric brain acticity changes during targeted emotional stimulation evaluated using sLORETA method

Name: Electrical cerebral activity changes during targeted emotional stimulation, evaluated by sLORETA Goals: The main goal of this thesis is the comparison of electrical brain activity changes during targeted emotional stimulation. Method: The research was conducted by measuring electrical cerebral activity using Natus Neurology 32-channel Nicolet™EEG Wireless Amplifier 32/64 device. The activity measurements were taken by an EEG Electro-cap with a total of 19 flat registration electrodes (Fp1, Fp2, F7, F3, Fz, F8, T5, T3, C3, Cz, C4, T4, T6, P3, Pz, 36 P4, O1, O2), placed in accord with the internationally used 10-20 system. The impendance resistance did not exceed 10 kΩ, with a sampling frequency of 512 Hz and a bandpass of 0,5-70 Hz. Resulting data was then processed using NeuroGuide programme. A 30s long, zero-artifact EEG section was then chosen to be exported to sLORETA programme. Probands were divided randomly into three research groups - positive, neutral and negative. Each proband was asked to pass the VVIQ imagination vividity questionnaire. In the next phase, each participant was asked to undergo a three week long imagination training programme, consisting of watching VR videos and targeted imaginations of walking, three times a week. While in the VR simulation, music and sound effect..
