Dynamics of random neural networks with bistable units

M Stern, H Sompolinsky, LF Abbott - Physical Review E, 2014 - APS
We construct and analyze a rate-based neural network model in which self-interacting units
represent clusters of neurons with strong local connectivity and random interunit connections …

Transition to chaos in random networks with cell-type-specific connectivity

J Aljadeff, M Stern, T Sharpee - Physical review letters, 2015 - APS
In neural circuits, statistical connectivity rules strongly depend on cell-type identity. We study
dynamics of neural networks with cell-type-specific connectivity by extending the dynamic …

A transformation from temporal to ensemble coding in a model of piriform cortex

M Stern, KA Bolding, LF Abbott, KM Franks - Elife, 2018 - elifesciences.org
10.7554/eLife.34831.001 Different coding strategies are used to represent odor information
at various stages of the mammalian olfactory system. A temporal latency code represents …

A reservoir of timescales emerges in recurrent circuits with heterogeneous neural assemblies

M Stern, N Istrate, L Mazzucato - Elife, 2023 - elifesciences.org
The temporal activity of many physical and biological systems, from complex networks to
neural circuits, exhibits fluctuations simultaneously varying over a large range of timescales. …

[PDF][PDF] Numerical cognition based on precise counting with a single spiking neuron

H Rapp, MP Nawrot, M Stern - IScience, 2020 - cell.com
Insects are able to solve basic numerical cognition tasks. We show that estimation of numerosity
can be realized and learned by a single spiking neuron with an appropriate synaptic …

Eigenvalues of block structured asymmetric random matrices

J Aljadeff, D Renfrew, M Stern - Journal of Mathematical Physics, 2015 - pubs.aip.org
We study the spectrum of an asymmetric random matrix with block structured variances. The
rows and columns of the random square matrix are divided into D partitions with arbitrary …

A reservoir of timescales in random neural networks

M Stern, N Istrate, L Mazzucato - arXiv preprint arXiv:2110.09165, 2021 - arxiv.org
The temporal activity of many biological systems, including neural circuits, exhibits fluctuations
simultaneously varying over a large range of timescales. The mechanisms leading to this …

[PDF][PDF] Functional plasticity of odor representations during motherhood

A Vinograd, Y Fuchs-Shlomai, M Stern, D Mukherjee… - Cell Reports, 2017 - cell.com
Motherhood is accompanied by new behaviors aimed at ensuring the wellbeing of the
offspring. Olfaction plays a key role in guiding maternal behaviors during this transition. We …

[HTML][HTML] Plume dynamics structure the spatiotemporal activity of mitral/tufted cell networks in the mouse olfactory bulb

…, N Rigolli, MF Tariq, LM Suarez, M Stern… - Frontiers in Cellular …, 2021 - frontiersin.org
Although mice locate resources using turbulent airborne odor plumes, the stochasticity and
intermittency of fluctuating plumes create challenges for interpreting odor cues in natural …

Inferring the spiking rate of a population of neurons from wide-field calcium imaging

M Stern, E Shea-Brown, D Witten - BioRxiv, 2020 - biorxiv.org
Wide-field calcium imaging techniques allow recordings of high-resolution neuronal activity
across one or more brain regions. However, since the recordings capture light emission …
