Rapp, H., Nawrot, M. P., Stern, M.

We show that estimation of numerosity can be realized and learned by a single spiking neuron with an appropriate synaptic plasticity rule. We propose that using action potentials to represent basic numerical concepts with a single spiking neuron is beneficial for organisms with small brains and limited neuronal resources.

Our model demonstrates how piriform cortex circuitry can implement multiplexed ensemble-identity/temporal-concentration odor coding.

Motherhood is associated with changes in neural circuits that affect how the
mother senses her surroundings. We show that durimg motherhood neurons of the bulb have elevated inhibition, and odor coding of natural odors is improved.

Aljadeff, J.*, Stern, M.*, Sharpee, T.

We study dynamics of neural networks with cell-type specific connectivity by extending the dynamic mean field method.

Stern, M., Sompolinsky H., Abbott L.F.

We construct and analyze a rate-based neural network model in which self-interacting units represent clusters
of neurons with strong local connectivity. Simulation results, mean-field calculations, and stability analysis reveal an interesting dynamical regime exhibiting transient but long-lived chaotic activity that combines features of chaotic and multiple fixed-point attractors.

Stern, M., Shea-Brown E. T., Witten D.

We develop and test novel
methods to deconvolve the calcium traces and reveal the underlying neural spiking rate.

We precisely track plume dynamics and image glomerular responses to this fluctuating input. We find that a consistent portion of Mitral cell activity in glomeruli follows odor concentration dynamics,and the strongest responding glomeruli are the best at following fluctuations within odor plumes.

Stern, M., Shea-Brown, E.

We review the Hopfield model (1982) in light of Krotov & Hopfield (2019). The Hopfield model (1982) has proved to be one of the most influential theoretical models in neuroscience. At its core lies the idea that a pattern of sustained neural activity can represent a memory.

Aljadeff J.*, Renfrew D., Stern M.*

We study the spectrum of an asymmetric random matrix with block structured variances.
