 Like Newsome, the authors reach for introspection. Yet they might undersell their result, for it seems that the animals are having a tactile hallucination: (a) Penfield showed that stimulation of primary sensory cortices like S1 induces hallucinations in humans; (b) action is engaged not at low stimulation of S1 in monkeys but only at higher level stimulation; (c) at that point, when the stimulation grabs their attention, the monkeys do what they were trained to do, namely discriminate stimuli, either with (d) just mechanical stimulation (normal experience), or (e) with a mix of mechanical and microstimulation or with just microstimulation; (f) given the behavioral equivalence of these three cases, one might then argue that if performance in the mechanical stimulation cases involves conscious tactile experience, then that same experience is involved in the other cases.
