Fmri fixation

WebApr 15, 2024 · To allow firm head-fixation at multiple habituation and fMRI time points, a chronic implant compatible with a 22-mm diameter MRI transmit-receive single loop coil was attached on the skull of the rats. The protocol was similar to that described earlier (Paasonen et al., 2024). WebThe fMRI task consisted of 96 trials, divided into 2 sessions (48 trials each). During the trial (10 s), a picture was presented with a sentence describing the picture (until the participant responded by pressing a YES or NO button, up to 5 s), followed by a screen with a fixation cross (minimally 5 s).
