Dendritic computations, dendritic spiking and dendritic plasticity in nanoelectronic neurons

摘要

Dendritic computations play a major role in the processing that occurs within each cortical neuron. In particular, for many pyramidal neurons, dendritic spiking has a major effect on neural behavior and must be modeled in order to capture nonlinear response of a neuron to its presynaptic inputs. This paper presents electronic circuits for dendritic spiking that demonstrate the global and local reset of dendritic spiking mechanisms. The dendritic computations are illustrated with circuits simulating entire cortical neurons, using carbon nanotube FET SPICE models.
