The second lecture will open up Deleuze’s long standing interest in neurophilosophy and look again at the brain’s confrontation with chaos. By doing so two main questions are posed: what can be done to a brain and what can a brain do? The first looks at the rise of so-called neuroculture, and focuses particular attention on the inventions of neuromarketing as an extension of cognitive labour. These new techniques of persuasion and absorption are intended to capture the chemical firings of the neuron and put it to work in new ways. The latter explores the potential of a nomadic brain that can confront chaos and escape the objectified brains of neuroculture. Here Deleuze’s interest in the relation between science, art and philosophy helps to prompt important questions for this event.The workshop that follows this lecture asks how the common brains of artists, scientists and philosophers can respond to chaos, each other, and more significantly, how do they become nomadic.
