Linear Modeling of Neural Response
This unit focuses on linear models for modeling the relationship between continuous neural recordings and events like stimuli.
The first two lessons will focus on the theoretical background: First you’ll learn how to apply linear regression and interpret the estimated coefficients. You’ll also see how ridge regularization can help to prevent overfitting and allow the model to make better predictions on new unseen data. The second lesson will then extend the linear model to relationships that are not instantaneous (like the neural response to stimuli) by introducing time-lags.
The third lesson will introduce mTRFpy, a package that provides a convenient interface for applying linear models to neural data and explore its application for modeling neural responses to continuous naturalistic speech.
Sessions
Linear Regression and Regularization
Use ordinary least squares (OLS) regression and ridge regularization to model the relationship between variables
Linear Regression Across Time-Lags
Create time-lagged design matrices and perform regularized regression to model time-varying relationships between stimulus and response
Modeling Cortical Responses to Naturalistic Speech
Use the mTRFpy package to model the relationship between speech features and neural responses
