Once upon a time, neuroscience was born. A dazzling array of neurotechnologies emerged that, according to popular belief, have finally begun to unlock the secrets of the brain. But as the brain sciences now extend into all corners of cultural, social, political, and economic life, a yet newer world has taken shape: “neuroculture,” which goes further than ever before to tackle the profound ethical implications we face in consequence.

The Assemblage Brain unveils a major new concept of sense making, one that challenges conventional scientific and philosophical understandings of the brain. Drawing on Deleuze and Guattari, Tony D. Sampson calls for a radical critical theory that operates in the interferences between philosophy, science, art, and politics. From this novel perspective the book is structured around two questions: “What can be done to a brain?” and “What can a brain do?” Sampson examines the rise of neuroeconomics in informing significant developments in computer work, marketing, and the neuropharmaceutical control of inattentiveness in the classroom. Moving beyond the neurocapitalist framework, he then reestablishes a place for proto-subjectivity in which biological and cultural distinctions are reintegrated in an understanding of the brain as an assemblage. 

The Assemblage Brain unravels the conventional image of thought that underpins many scientific and philosophical accounts of how sense is produced, providing a new view of our current time in which capitalism and the neurosciences endeavor to colonize the brain. 

In this thought-provoking work, Tony D. Sampson presents a contagion theory fit for the age of networks. Unlike memes and microbial contagions, Virality does not restrict itself to biological analogies and medical metaphors. It instead points toward a theory of contagious assemblages, events, and affects. For Sampson, contagion is not necessarily a positive or negative force of encounter; it is how society comes together and relates.

Sampson argues that a biological knowledge of contagion has been universally distributed by way of the rhetoric of fear used in the antivirus industry and other popular discourses surrounding network culture. This awareness is also detectable in concerns over too much connectivity, such as problems of global financial crisis and terrorism. Sampson’s “virality” is as established as that of the biological meme and microbe but is not understood through representational thinking expressed in metaphors and analogies. Rather, Sampson interprets contagion theory through the social relationalities first established in Gabriel Tarde’s microsociology and subsequently recognized in Gilles Deleuze’s ontological worldview.

According to Sampson, the reliance on representational thinking to explain the social behavior of networking—including that engaged in by nonhumans such as computers—allows language to overcategorize and limit analysis by imposing identities, oppositions, and resemblances on contagious phenomena. It is the power of these categories that impinges on social and cultural domains. Assemblage theory, on the other hand, is all about relationality and encounter, helping us to understand the viral as a positively sociological event, building from the molecular outward, long before it becomes biological.
