<div dir="ltr"><div>Dear Friends,</div>
<div> </div>
<div>I am currently working on Human Emotion Recognition using EEG. i am using Audio-Visual Induction based </div>
<div>protocol for evoking the emotions. i have tried in the website for getting the universal standard video clips for</div>
<div>inducing emotions, i am tried to succeed much. Also, i cant find any short time duration video clips for inducing</div>
<div>Anger and sad emotions. In addition, i want to if any standard data base is available for the emotion recognition</div>
<div>experiemtn. If any one knows about the details means, can you pl forward to me.</div>
<div> </div>
<div>Thanks in advance,</div>

<p><span style="COLOR: black"></span> </p>
<p><span style="COLOR: black">A post-doctoral research position is available in the Human Neuromechanics Laboratory to study brain dynamics during human locomotion using high density EEG. The research will involve studying brain dynamics in both healthy and spinal cord injured humans with simultaneous full body biomechanical analyses (kinematics, kinetics, EMG). The projects include collaborations with members of the University of Michigan Dept. of Physical Medicine and Rehabilitation and the UC San Diego Swartz Center for Computational Neuroscience. Experience with Matlab, EEG, and/or gait biomechanics is desirable. Interested candidates should submit a curriculum vitae, letter of interest, and contact information for three references to Dan Ferris, Division of Kinesiology, University of Michigan (<a href="mailto:ferrisdp@umich.edu" target="_blank">ferrisdp@umich.edu</a>). Review of applications will begin immediately. <b>This position is for U.S. citizens and permanent residents only.</b> For additional information, please feel free to contact me by e-mail.</span></p>

<div dir="ltr">Hello,<br> I am trying to figure out how to bandpass filter an EEG data set. From skimming the literature it appears that Butterworth filters are commonly used for filtering EEG data and strike a good compromise between the steepness of the transition band and ripples in the pass and stop bands. It's also clear to me that the higher the order of the filter, the steeper the transition band. Are there any cons to using a higher order Butterworth filter?<br>

I am a beginner in eeglab and try to figure out some basic functions in eeglab. I like to adjust them to my needs.<br>
<br>Is it possible to rereference the data using one of my channels such that the rereferenced dataset would be referenced against the new channel divided by 2?<br>resulting channel = old channel - (specific channel / 2)<br>
By using 'reref' I wasnt able to do this..<br><br>How can I extract epochs by using conditional expressions such as: Extract all epochs after event-code x but only if event-code y is following within the next z ms?<br>
<br>Have you any ideas, why 'h' instead of 'EEG.history' doesnt work on my computer?<br><br>Thank you very much in advance!<br>Best regards,<br>Nils<br><br><br><br><br>-- <br>Dipl. Psych. Nils Skotara<br>Universität-Hamburg<br>

Date: Tue, 29 Jul 2008 12:00:04 -0700<br>Subject: [Eeglablist] ICA weights blowing up<br>
<div dir="ltr">Hi, my lab has been using ICA to identify blinks and other artifacts. However I've found that about 20% of subjects appear to have data that ICA can't find a good solution for. runica takes hours to do just a few steps and eventually matlab crashes. All of our data after acquisition is processed in eeglab. The data is 128 channels, which we reduce to 75 using PCA. After premilinary artifact rejection, each subject has about 30 minutes worth of epoched data. I use extended runica, although other versions of ica didn't do any better. I did some troubleshooting with the data and runica.m and it seems as though, for the "bad" subjects, the weights are blowing up every time. For some subjects, their data is just poor quality but for others, their data looks clean, and I don't know why ICA isn't working for them. Is there anything I can do to get around this problem? <br>
