If these models are used to understand and interpret electrophysiological data, it is important to reliably estimate the values of the model\u2019s parameters. However, there are no standard methods for the parameter estimation of Integrate-and-fire models. Here, we identify the model parameters of an adaptive integrate-and-fire neuron with temporally correlated noise by analyzing membrane potential and spike trains in response to a current step. Explicit formulas for the parameters are analytically derived by stationary and time-dependent ensemble averaging of the model dynamics. Specifically, we give mathematical expressions for the adaptation time constant, the adaptation strength, the membrane time constant, and the mean constant input current. These theoretical predictions are validated by numerical simulations for a broad range of system parameters. Importantly, we demonstrate that parameters can be extracted by using only a modest number of trials. This is particularly encouraging, as the number of trials in experimental settings is often limited. Hence, our formulas may be useful for the extraction of effective parameters from neurophysiological data obtained from standard current-step experiments.<\/jats:p>","DOI":"10.1007\/s00422-024-01000-2","type":"journal-article","created":{"date-parts":[[2024,12,29]],"date-time":"2024-12-29T23:45:02Z","timestamp":1735515902000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Extraction of parameters of a stochastic integrate-and-fire model with adaptation from voltage recordings"],"prefix":"10.1007","volume":"119","author":[{"given":"Lilli","family":"Kiessling","sequence":"first","affiliation":[]},{"given":"Benjamin","family":"Lindner","sequence":"additional","affiliation":[]}],"member":"297","published-online":{"date-parts":[[2024,12,30]]},"reference":[{"key":"1000_CR1","doi-asserted-by":"publisher","first-page":"656","DOI":"10.1152\/jn.01107.2007","volume":"99","author":"L Badel","year":"2008","unstructured":"Badel L, Lefort S, Brette R, Petersen CC, Gerstner W, Richardson MJ (2008a) Extracting non-linear integrate-and-fire models from experimental data using dynamic I-V curves.
