The present study seeks to evaluate the relationship between psychology and neuroscience. Therefore, taking the Actor-Network Theory (ANT) and Bruno Latour s work, specifically, it can be noticed the socio-technical networks that trace the field of neuroscience. Armed with some basic concepts such as factishes, black box and sociotechnical network, pointing up the assemblages made from the network formed, and scientific work on the brain as the entry point. It has assigned a specific value to the brain that produces an assemblage of a series of actants. This network of actants constitute the field of neuroscience, in which psychology articulates in a certain way. When psychology articulates with neurosciences, there are some interests to certain psi practices, disposed with a naturalization of thought. At the same time, we observe that, since its elaborations, such practices have a scientific claim, which is great harmony in the work neuroscience.
