Demonstration that sublinear dendrites enable linearly non-separable computations

Romain Cazé, Alexandra Tran-Van-Minh, Boris Gutkin, David Digregorio

ABSTRACT Theory predicts that nonlinear summation of synaptic potentials within dendrites allows neurons to perform linearly non-separable computations (LNSCs). Using Boolean analysis approaches, we predicted that both supralinear and sublinear synaptic summation could allow single neurons to...
