New online courses: mikexcohen.comHi All, 

This isn’t an eeglab specific question… apologies if I’m stretching list rules. 

Do you disinfect your EEG cap? 

I’m talking about the cap, not the electrodes themselves, and in the context of standard University research use (ie. undergrads, not patients). 

I’ve worked in institutions that do, and in institutions that don’t. Some manufacturers appear to take it for granted (eg. ECI), others suggest avoiding it (eg. Biosemi). 

I get the impression that disinfectant reduces the life of the cap by breaking down the elasticity. Much more than that, though, I really dislike having to deal with glutaraldehyde solution. It’s nasty stuff, it has a short shelf life, and I expect that we as a community put a fair amount of it in our local water supplies (probably a drop in the proverbial bucket when one considers the medical system as a whole, but still). 

In your opinion, is it necessary? Does anyone know of any university / medical / governmental regulations that require it?

Dear all, 

there is a Post-Doc position available at the Neuroplasticity Lab at the City College of New York. Successful applicant will work with Dr. M. Felice Ghilardi and her team on a NIH-funded project investigating the functional significance of local sleep in humans. Our project, in partnership with the University of Wisconsin-Madison, is aimed to determine if sleep in humans occurs locally, in small-circumscribed regions of the cerebral cortex, during normal waking hours and if it is related to intense practice.

Requirements: PhD or equivalent degree in neuroscience, psychology, engineering or a related discipline is required. Ideal candidates would have extensive experience in HD-EEG data analysis and be proficient in Matlab programming. 

Preference will be given to candidates with experience in sleep research; background in cognitive neuroscience and experimental psychology; interest/experience with clinical populations; experience in task design and analysis for cognitive experiments.

Position available from January 2018.  Interested applicants should email: (a) CV, (b) statement of post-doctoral and career goals, and (c) letters and/or contact information for two references to Dr. Elisa Tatti <etatti at ccny.cuny.edu>. 

Stipend levels are in line with experience and NIH.  A two-year commitment is required.

Advert:
The School of Psychology at the University of Birmingham is looking for a bright and motivated PhD student to join the Charest Laboratory (iancharest.com). The PhD position to be filled is part of a project recently funded by a European Research Council Starting Grant entitled: "Spatio-Temporal Attention and Representation Tracking: the precise neural architecture of conscious object perception" (START). 

The Project: 
START is an ambitious programme of work that will make use of cutting-edge multivariate pattern analyses (MVPA) techniques to reveal the brain mechanisms that are critical for consciously perceiving visual objects in tasks that manipulate conscious access to visual information. The ability to consciously recognise faces, objects, or sounds is crucial for adaptive behaviour and survival. Yet, how our conscious experience of the world emerges in our brain remains unknown. The overall aim of the START programme is to fill an important gap in our understanding of consciousness by elucidating the neural underpinnings of conscious access. How does the brain select relevant information among distractors, and keep this information in mind? Why does our ability to consciously recognise salient objects sometimes fail under pressure and exhibit variability across days and individuals? START will try to address these important questions by precisely tracking where in the brain and when in time the representations critical for conscious access are established, by using novel approaches of Representational Similarity Analyses which combines the strengths of EEG, fMRI, and Deep Convolutional Neuronal Networks. This project will provide new insights on the precise spatio-temporal dynamics of conscious access, the mechanisms governing it, and the idiosyncratic subtleties behind the meanderings of consciousness. 

The candidate: 
The successful candidate will have (or be in the process of obtaining) a Masters degree in cognitive neuroscience or a related field. Previous experience with psychophysical tasks that manipulate conscious access in vision is desirable. Given the nature of the project, good understanding of and experience with fMRI, EEG/MEG and data analysis is desirable. Experience in using matlab or python (and Psychtoolbox or PsychoPy) is a requirement. The successful applicant will have experience with multivariate pattern analyses (Representational Similarity Analysis, Fisher linear discriminants, etc) of neuroimaging data. This post will require designing experiments, collecting and analysing data associated with the project, preparing manuscripts for publication, presenting results at national and international conferences and the possible supervision of research assistants and students. 

The School: 
The School of Psychology at the University of Birmingham (http://www.birmingham.ac.uk/schools/psychology/index.aspx) is one of the largest and most successful in the UK, currently ranked in the top 5 Schools in the country (REF 2014). The School is soon to move to new accommodation in the form of a fully refurbished, purpose-designed space and a new-build Centre for Human Brain Health that will house our new MRI, MEG, EEG, NIRS, sleep lab, and the recently appointed Chair in Translational Neuroscience. The University of Birmingham is an equal opportunities employer. The School of Psychology has a Bronze Athena SWAN award and strives to maintain a flexible and supportive environment that enables its staff to flourish. 

For informal enquiries about the project please contact Dr. Ian Charest (i.charest at bham.ac.uk). Formal applications must be made via the postgraduate admissions system in the School of Psychology. Applicants are encouraged to attach to their application a short and original project proposal (500 words).

Dear EEG list,

Using code, I want to work on the component level. I have interpolated X number of electrodes, but reduced the rank of the data with PCA before ICA to total number of electrodes – X.

I now want to perform analysis on the components, but I am wondering how to use the following structs to calculate a matrix of ICA components, and how to link this to topographic information (I know it cannot map to channels anymore).

I am aware of the following fields.

            EEG.icawinv

            EEG.icasphere

            EEG.icaweights

            EEG.icachansind

                          EEG.data with channel level data (some channels interpolated).

Best wishes,

Jumana

Hello Tyler, not sure if this helps: it's totally possible that eeg_lat2point removes or discounts 2 data points. It's unclear whether clean_windows can or should accomodate the changes made by eeg_lat2point. As this is unlikely to lead to a major issue, you could modify the sample_mask (inside the code) to take 2 less datapoints, although this might lead to several changes that one would need to make. Another option is to contact the developer Dr.Kothe? directly. Thanks very much for letting the list know when you have a solution, as it would benefit other users to learn from your experience.

Dear EEGLAB

Im having a great time using the clean_rawdata toolbox, however, I ran into a bug recently which is preventing me from using the function vis_artifacts. The bug occurs after Ive used clean_windows and try to compare the output data to the input data. The following error occurs:

Subscripted assignment dimension mismatch.
Error in vis_artifacts/expand_ rejections (line 334)        tmpdata(EEG.etc.clean_channel_ mask,EEG.etc.clean_sample_ mask)        = EEG.data;
Error in vis_artifacts (line 101)    new = expand_rejections(to_ continuous(new));

Digging into the code I find out that the number of true logicals in EEG.etc.clean_sample_mask is equal to 2449098, whereas the number of data points in my 'cleaned' data is 2449096. Returning to the clean_windows function, I get the following warning:

Warning: eeg_lat2point(): Points out of range detected.Points replaced with maximum value > In eeg_lat2point (line 101)  In pop_select (line 534)  In clean_windows (line 136)  In clean_artifacts (line 226)  In clean_rawdata (line 83)  In mcgurk_clean_data (line 187) 

This suggests to me that eeg_lat2point may have removed some data points? Or do you think that clean_windows should accommodate for changes made my eeg_lat2point? Like the subject of this email suggests, I dont know where the bug is.

I can confirm that I am using clean_rawdata version 0.32
