Stereopsis and 3D surface perception by spiking neurons in laminar cortical circuits: A method for converting neural rate models into spiking models

Y Cao, S Grossberg - Neural Networks, 2012 - Elsevier
A laminar cortical model of stereopsis and 3D surface perception is developed and
simulated. The model shows how spiking neurons that interact in hierarchically organized …

A computational model for generation of the P300 evoked potential component

BK Bonala, BH Jansen - Journal of Integrative Neuroscience, 2012 - World Scientific
The P300 is an endogenously evoked potential with amplitude and latency depending on
the amount of information carried by the stimulus rather than its physical characteristics. It …
