Connectivity structure and dynamics of nonlinear recurrent neural networks

Studies of the dynamics of nonlinear recurrent neural networks often assume independent and identically distributed couplings, but large-scale connectomics data indicate that biological neural circuits exhibit markedly different connectivity …

Simplified derivations for high-dimensional convex learning problems

Statistical-physics calculations in machine learning and theoretical neuroscience often involve lengthy derivations that obscure physical interpretation. Here, we give concise, non-replica derivations of several key results and highlight their …

Structure of activity in multiregion recurrent neural networks

Neural circuits comprise multiple interconnected regions, each with complex dynamics. The interplay between local and global activity is thought to underlie computational flexibility, yet the structure of multiregion neural activity and its origins …

Theory of coupled neuronal-synaptic dynamics

We study a network model in which neurons and synapses are mutually coupled dynamic variables.

Dimension of activity in random neural networks

We derive the structure of time-lagged cross-covariances between neurons in nonlinear recurrent neural networks with random synaptic couplings.

Olfactory landmarks and path integration converge to form a cognitive spatial map

The convergence of internal path integration and external sensory landmarks generates a cognitive spatial map in the hippocampus. We studied how localized odor cues are recognized as landmarks by recording the activity of neurons in CA1 during a …
