EGI Hydrocel sLORETA coordinates and Transform Files

Past few months have been crazy with postdoc interviewing and paper writing. Just thought I’d take a few minutes out to share some useful files for folks interested in analyzing EEG data from the 256 channel EGI Hydrocel System in sLORETA. Can be a pain figuring out how transform the EGI coordinates to the standardized MNI space in order to estimate an sLORETA transformation matrix, so this’ll might save you some time if you’re trying to do that. These files assume Cz has been retained but just go ahead and delete the last line of the .sxyz file in your favorite text editor and use that file to recompute the sLORETA transform if you’ve dumped Cz from your files. Happy Analyzing! Coordinate file : Hydrocel_257_coordinates.sxyz sLORETA spinv transformation coordinates : Hydrocel_257_coordinates

Is this Image Fake?

Have you seen this image and wondered, “Is that real?”. Tried hunting down a source that could conclusively answer that only to be met by mountains of pseudoscience? If so, you’re in luck. The answer’s right here. After finding it for myself I figured it was worth taking a few minutes to put it out there just so there’s a little candle out there for folks who happen to be searching for the truth on this in the future. About a week ago a friend of mine drew my attention to this image. It came from a popular science article (link) on the how a baby’s interaction with its mother “determined” whether its brain developed normally. Now the article itself was generally decently worded as far as pop brain science stuff goes but it hinted very strongly that it was the lack of an affectionate bond that was the primary …

Why Pseudoscience is Dangerous

We’ve all seen them. Scrolling down our Facebook feeds. From the extreme “Eat cinnamon to prevent cancer”. “Grow these plants in your house to filter out toxins” to the plausible sounding but nonetheless empirically awful claims on the powers of coffee, power posing, red wine etc. etc. There’s so much junk out there that it’s a waste of time to debunk each one personally. And there’s really no point. Whack something down and something else will just rise to take its place. In my own life, I steer well clear of garbage science. It’s not hard to do, just look up the journals that are being cited and if no journal is being cited, toss it out. You’ll be amazed at how much plausible “real science backed” stuff actually has no backing whatsoever. Ask someone else to do it though and you often get a range of laziness fueled reactions. …

My Take on Excelling in Graduate School

Like many, I had a slightly slow start to my graduate career before I started to learn how to really get things moving. As I move on to new pastures, I figured it be worth taking a few minutes to share some of the things that have helped me in my adventure + many more that I wish I had known or had taken more seriously coming in. Here’s a shortlist for them for folks thinking about graduate school or who know folks with plans that might find this useful! *Caveat : this list is psych-centric with an emphasis on folks interested in a academia, might be some useful bits in the mix for folk interested in applied work but I’d recommend checking out other sources for tips on that! 1) Learn a Skill and get good at it, very good at it ideally Unless you happen to have a earth-shatteringly …

Temporal-Spatial Decomposition in ERP Analysis : A General Introduction

Most of my work focuses on EEG related measures. While I do conduct some single-trial, time-frequency, electrotomographic and connectivity based analyses, it’s hard to disregard the rich body of work involving classic ERP components. I suppose the analogue to “Ahh, but does it run Crysis” in the EEG world might be “Ahh, but does it P300”? (the overlap in the Venn diagrams of folks who get those jokes is might be fairly small, but I think it’s funny so it stays!). Focusing on the simple case of finding a P300, say to an auditory oddball paradigm. Imagine you went all out on equipment and collected some awesome 256 electrode high density datasets. What next? How do you decide When and Where that P300 component arises? No problem! I’ll just look at the literature and use what other folks use. A few hours later, you’re surrounded by papers proclaiming the P300 is …

Grand Canyon 1-day Summer Rim-to-Base Back Kaibab-Angel-Trail Hike

Glad to finally get this one-off the hiking bucket list! Just hiked this route last week on June 2nd. The Canyon Rim-to-Base Kaibab-to-Angel hike is a 27 kilometer route with a 1.5 kilometer descent followed by a 1.3 kilometer ascent. Is it hard? The range of disparate answers you’ll find for that simple question is nuts. On one hand you’ll see fit marathon runners talking about it as the hardest hike of their lives and on the other you’ll see mild-mannered older folk talking about how relaxing and fun the trek was. Frankly, it boils down to a few basic factors. The first thing to get out-of-the-way is the distance/elevation, the hike is at its heart a simple 17 mile hike with a +/- 1 mile ascent and descent. If you’ve done hill hiking before along similar distances there’s really nothing magically different about the trail itself (i.e. insanely steep …

First Post!

It’s high time I started a blog focused on both discussing my research work and passing on advice that I picked up on my academic adventure to folks who might be interested in a similar journey. In this blog I plan to write posts discussing my research work and findings, elaborate on experiment and EEG analysis code (soon to be uploaded!) I’ve uploaded for public use on online repositories and musings on various theoretical subjects and the academic life. Looking forward to writing on this~!
