Attractor dynamics of spatially correlated neural activity in the limbic system

JJ Knierim, K Zhang - Annual review of neuroscience, 2012 - annualreviews.org
Attractor networks are a popular computational construct used to model different brain
systems. These networks allow elegant computations that are thought to represent a number …

Fundamental limits on persistent activity in networks of noisy neurons

Y Burak, IR Fiete - Proceedings of the National Academy of …, 2012 - National Acad Sciences
Neural noise limits the fidelity of representations in the brain. This limitation has been
extensively analyzed for sensory coding. However, in short-term memory and integrator …

Neural information processing with feedback modulations

W Zhang, S Wu - Neural Computation, 2012 - direct.mit.edu
Descending feedback connections, together with ascending feedforward ones, are the
indispensable parts of the sensory pathways in the central nervous system. This study …

Correlated neural variability in persistent state networks

A Polk, A Litwin-Kumar… - Proceedings of the …, 2012 - National Acad Sciences
Neural activity that persists long after stimulus presentation is a biological correlate of short-
term memory. Variability in spiking activity causes persistent states to drift over time …

A network model of hallucinations

R Goekoop, J Looijestijn - Hallucinations: Research and practice, 2012 - Springer
The study of hallucinations is complicated by the huge number of factors that determine the
occurrence and phenomenological characteristics of these phenomena. Until recently, this …
