Fig. 1. Group mean differential ERP (n = 10). Stimuli: black line — images of food, gray line — images of body parts of emaciated people. Vertical — amplitude (mkV), horizontal — time (ms). Vertical dashed line (0 ms) reflects the time of stimulus presentation. Above each curve — name of EEG site
Fig. 2. Group mean P300, N1 and LPP component amplitude, two types of stimuli (images of food and images of body parts of emaciated people). Mean and standard error of mean. Difference between blocks: * — p < 0.05, # — p < 0.1
Fig. 3. Group mean classification accuracy, BCI algorithm, identification of
significant stimuli among neutral ones in two blocks (images of food and images of
body parts of emaciated people). Mean and standard error of mean. Difference
between blocks: * — p < 0.05
Table. P300, N1 and LPP amplitude values, response to presentation of stimuli (images of food and images of body parts of emaciated people). Mean ± standard
error of mean, mkV
