It seems that brain, thought and computer have become intertwined and now share a common fate. An important part of neuroscience not only requires a computational paradigm but also relies on technology to be operational. Experiments in neuroscience are built on the use of material apparatuses dependent on the computer. Isn’t the emergence of the computer in the last century based on a certain representation of thought and the brain? It has become difficult to distinguish among these three representations (computer, thought and brain) since they seem superimposed upon one another through a fiction that operates in a very concrete way on the world. I would like to explore this fiction in order to analyze how a form of speculation that favors what is possible over what is real can produce a technological “reality” that challenges all certainty. Our contemporary world seems to contain an anomaly of which we can only trace the shadow: parallel to the progress made in neuroscience, our nervous system is increasingly stimulated by an interconnected digital environment that leaves us no respite. It consumes us and we in turn consume it.
