Near-optimal information relay by the neuronal population of layer 4 barrel cortex

Authors Revah O, Wolf F, Gutnick MJ, Neef A Journal BioRxiv Citation bioRxiv 2024.02.15.580451. Abstract Cortical function reflects the coordinated activities of populations of neurons, which, in turn, depend on the speed with which each neuron can respond to input, as revealed by dynamic gain analysis. In Layer 4 of

Boosting of neural circuit chaos at the onset of collective oscillations

Authors Palmigiano A, Engelken R, Wolf F Journal eLife Citation eLife 12:RP90378. Abstract Neuronal spiking activity in cortical circuits is often temporally structured by collective rhythms. Rhythmic activity has been hypothesized to regulate temporal coding and to mediate the flexible routing of information flow across the cortex. Spiking neuronal circuits,

Signatures of heterogeneity in the statistical structure of target state aligned ensembles

Authors Lenner N, Häring M, Eule S, Großhans J, Wolf F Journal ArXiv Citation arXiv:2304.09719. Abstract Finite time convergence to functionally important target states is a key component of many biological processes. We previously found that the terminal approach phase of such dynamics exhibits universal types of stochastic dynamics that

Reverse-time analysis and boundary classification of directional biological dynamics with multiplicative noise

Authors Lenner N, Häring M, Eule S, Großhans J, Wolf F   Journal ArXiv   Citation arXiv:2304.04279.   Abstract The dynamics of living systems often serves the purpose of reaching functionally important target states. We previously proposed a theory to analyze stochastic biological dynamics evolving towards target states in reverse

Reverse-time analysis uncovers universality classes in directional biological dynamics

Authors Lenner N, Eule S, Großhans J, Wolf F Journal Arxiv Citation arXiv:2304.03226. Abstract Mesoscopic bio-systems typically evolve towards functionally important target states, such as cell-cycle checkpoints or decision boundaries for the release of specific behaviors. For the data-driven inference of the underlying directional out-of-equilibrium dynamics, we here develop a

Environmental enrichment enhances patterning and remodeling of synaptic nanoarchitecture as revealed by STED nanoscopy

Authors Wegner W, Steffens H, Gregor C, Wolf F, Willig KI Journal Elife Citation eLife 2022;11:e73603. Abstract Synaptic plasticity underlies long-lasting structural and functional changes to brain circuitry and its experience-dependent remodeling can be fundamentally enhanced by environmental enrichment. It is however unknown, whether and how the environmental enrichment alters
