Methods Eight healthy male subjects (aged 22-38) who participated in our study were asked: 1. to look at objects presented on a screen, 2. to manipulate objects that were put into their hands by one of the experimenter, 3. to hear a characteristic sound associated with specific objects, 4. to look at objects presented on a screen, while manipulating the same object and hearing the characteristic sound associated with the object. Between conditions, a specific baseline was implemented. FMRI measurements were performed on a SIEMENS VISION 1.5 T scanner utilising standard EPI sequences. Block design was used with pseudo-randomised order of condition. Data analysis was performed using SPM97 with a standard box-car reference function. Categorical comparison between the conditions and conjunction analysis were employed at a significance level of p
