Analysis of non-linearities in local field potential oscillations

Yeh C-H

This package includes scripts for calculating two sources of non-linearity in beta frequency band-Intrinsic mode functions (IMF). These are the sharpness around the extrema of the beta-IMF 
and the intra-wave instantaneous frequency variations in the gaps between these extrema, -a measure of the degree of non-linearity in these gaps (DoNgap).

Assistance with this dataset

We welcome researchers wishing to reuse our data to contact the creators of datasets. If you are unfamiliar with analysing the type of data we are sharing, have questions about the acquisition methodology, need additional help understanding a file format, or are interested in collaborating with us, please get in touch via email. Our current members have email addresses on our main site. The corresponding author of an associated publication, or the first or last creator of the dataset are likely to be able to assist, but in case of uncertainty on who to contact, email Ben Micklem, Research Support Manager at the MRC BNDU.
