 In a recent study, Hirshorn et al. (2016) used microstimulation to disrupt processing in lmFG in human epileptic patients with preoperatively implanted electrodes spanning that area. These electrodes are used to map sites that will be surgically removed to relieve intractable seizures. Subjects read words or letters during actual or sham microstimulation. Crucially, stimulation in lmFG selectively disrupted word and letter reading but not general form perception. During lmFG stimulation, one subject when presented with “illegal” reported not seeing the word (see   Movie S1 in Other Internet Resources). Rather, she reported thinking of different words (still, she did not report seeing different words). With “message” she reported thinking that an “n” was present. In a second patient, the identification of letters was completely disrupted (see    Movie S2 in Other Internet Resources).  The patient reported seeing an “A” when presented with an “X”, and then an “F” and “H” when presented with “C”. The results suggest that normal word reading requires lmFG processing to parse linguistic forms. A plausible hypothesis is that microstimulation disrupted visual experience of specific types of stimuli, a test of necessity. That said, the first patient’s introspective reports of thinking rather than seeing words complicates matters.
