Mental chess allows investigating the network of brain areas underlying mental imagery in highly trained individuals. Three amateur chess players (ELO rating > 2000) performed imagined chess movements (rule retrieval by examining movement options, initial moves during opening session) using an alternating task design (30 s activation, 30 s baseline). Control conditions included continuous multiplication of single-digit numbers and arbitrary movements on the chessboard. Real-time whole brain fMRI was performed on a 1.5 T MR scanner (TR 3 s, TE 66 ms, voxel size 6x6x6 mm3). Rule retrieval versus number multiplication resulted in strong activations in parietal cortex (precuneus) and weaker activity in temporal cortex, bilateral dorsolateral prefrontal cortex (BA46, BA9), bilateral motor cortex and in visual areas, possibly area V4/V5, consistent with results from PET and SPECT studies (1,2). Opening moves versus arbitrary movements, as well as rule retrieval versus arbitrary movements, resulted in predominantly left prefrontal activation. These preliminary fMRI observations support previously reported circuits and further reveal the involvement of the visual cortex during imagined movements on the chessboard (motor and visual imagery). Additionally the results demonstrate the feasibility of real-time fMRI to monitor cognitive function involving mental imagery.
