Connectivity structure and dynamics of nonlinear recurrent neural networks
David G. Clark, Owen Marschall, Alexander van Meegen +1
Studies of the dynamics of nonlinear recurrent neural networks often assume independent and identically distributed couplings, but large-scale connectomics data indicate that biolo…
Dimension of activity in random neural networks
David G. Clark, L. F. Abbott, Ashok Litwin-Kumar
Neural networks are high-dimensional nonlinear dynamical systems that process information through the coordinated activity of many connected units. Understanding how biological and…
Action-modulated midbrain dopamine activity arises from distributed control policies
Jack Lindsey, Ashok Litwin-Kumar
Animal behavior is driven by multiple brain regions working in parallel with distinct control policies. We present a biologically plausible model of off-policy reinforcement learni…
Self-organization of microcircuits in networks of neurons with plastic synapses
Gabriel Koch Ocker, Ashok Litwin-Kumar, Brent Doiron
The synaptic connectivity of cortical networks features an overrepresentation of certain wiring motifs compared to simple random-network models. This structure is shaped, in part,…
