Biography:

Jean-Pierre Changeux PhD is International Faculty at the Kavli Institute for Brain & Mind University of California San Diego and professor at the Collège de France & Institut Pasteur, Paris.

His PhD studies in the laboratory of Jacques Monod, led to the discovery that chemical signals regulate the biological activity of proteins by acting at “allosteric” sites distinct from the biologically active sites via a conformational change (1961-1965). He then proposed (1964) that this type of regulation applies to receptor mechanisms engaged in the transmission of chemical signals in the nervous system and through his life-time work, validated this insight. His studies were initiated by the first identification of a neurotransmitter receptor: the nicotinic acetylcholine receptor together with Lee & Kasai (1970) and culminated by a contribution, together with Corringer & Delarue, to establishing the 3-D structure and conformational transition of prokaryotic orthologs of nicotinic receptors by X-ray crystallography and molecular dynamics (2005-15). He and his colleagues also deciphered the topology of allosteric modulatory sites for pharmacological ligands (1996-2011), thereby substantiating a novel strategy of drug design based on allosteric modulation. Moving to neuronal networks, Changeux, together with Courrège & Danchin (1973, 1976) formulated and experimentally tested the theory that long-term epigenesis of neuronal networks occurs by the activity-dependant selective stabilization, and elimination, of developing synapses. Last, in particular with Dehaene, he proposed and tested models for defined cognitive tasks and their pharmacological modulation in particular, a neuronal hypothesis for conscious processing, implicating a “global neuronal workspace” composed of a brain-scale horizontal network of long axon neurons (1991- (1998-2015).

Changeux has published several books including Neuronal Man (1985), What Makes Us Think? (with Paul Ricoeur) (2002), Physiology of truth (2002).

His academic accolades include the Gairdner award (1978), the Wolf prize (1983), the Goodman and Gilman Award in drug receptor pharmacology (1994), the Balzan Prize (2001), the US National Academy of Sciences Award in Neurosciences (2007), the Japanese Society for the Promotion of Science Award for Eminent Scientists,Tokyo (2012) and the Olav Thon Foundation's International Research Award for Natural Sciences and Medicine, Oslo (2016).
