A learning rule for place fields in a cortical model: theta phase precession as a network effect
Silvia Scarpetta, Maria Marinaro
We show that a model of the hippocampus introduced recently by Scarpetta, Zhaoping & Hertz ([2002] Neural Computation 14(10):2371-96), explains the theta phase precession phenomena…

Effects of Noise in a Cortical Neural Model
Maria Marinaro, Silvia Scarpetta
Recently Segev et al. (Phys. Rev. E 64,2001, Phys.Rev.Let. 88, 2002) made long-term observations of spontaneous activity of in-vitro cortical networks, which differ from prediction…

Mathematical Analysis and Simulations of the Neural Circuit for Locomotion in Lamprey
Li Zhaoping, Alex Lewis, Silvia Scarpetta
We analyze the dynamics of the neural circuit of the lamprey central pattern generator (CPG). This analysis provides insights into how neural interactions form oscillators and enab…
