Methods for characterising language processing in time and space

Spatiotemporal Searchlight Representational Similarity Analysis (RSA) in fMRI and EMEG

We have generalised the spatial searchlight Representational Similarity Analysis (RSA; Kriegeskorte et al., 2006) to time resolved imaging techniques such as EEG and MEG.

The software is released as open-source.

Kymata

Kymata searches for the output of computable functions, encoded in the medium of postsynaptic apical dendritic current (as estimated using electro- and magneto-encephalographic (EMEG) recordings).

Mapping tonotopic organization in human temporal cortex

We utilised a spatiotemporal searchlight approach to successfully decode information about patterns of neuronal frequency preference and selectivity in bilateral superior temporal cortex.
