Telepathic Rats

From what I can gather,  the experiment referred to in this discussion may have just involved transmitting the excitation pattern of motor neurons associated with pressing the (say) left button rather than transmitting any “conceptual” association of that button with the subsequent reward. The receiving rat would then reflexively press the left button and after getting the reward might then be reinforced and so have “learned” the association on the basis of its own experience. What would be needed to demonstrate the transmission of anything close to learning would be for stimulation of the receiving rat prior to exposure to the apparatus to have the effect of increasing its likelihood of making  a subsequent correct choice while NOT stimulated.
