The mTRF Toolbox is a MATLAB repository that permits the fast computation of the linear stimulus-response mapping of any sensory system in
the forward or backward direction. It is suitable for analysing multi-channel EEG, MEG, ECoG and EMG data. The forward encoding model, or
temporal response function (TRF) as it is commonly known, can be used to investigate information processing in neuronal populations using
conventional time-frequency and source analysis techniques. In addition, TRFs can be used to predict the spectrotemporal dynamics of
future neural responses to unseen stimulus sequences. Stimulus reconstruction can also be performed using backward decoding models that
project the multi-channel population responses back to the dynamics of the causal stimulus signal. The mTRF Toolbox facilitates the use of
extended continuous stimuli in electrophysiological studies compared to conventional time-locked averaging approaches which require the
use of discrete, isolated stimulus events. This allows researchers to investigate of how neural systems process dynamic environmental
signals such as speech, music and motion.
