Plastic Reason is a study of the efforts of a few Parisian neurobiologists to undermine this rigid conception of the central nervous system and to show that basic embryogenetic processes - most spectacularly the emergence of new cellular tissue in the form of new neurons, axons, dendrites, and synapses - continue in the mature brain. Furthermore, these researchers sought to demonstrate that the new tissues are still unspecific and hence literally plastic, and that this cellular plasticity is constitutive of the possibility of the human.
