Paul L. Gribble, Ph.D.
[ bio ]

The lab is located in the Department of Psychology at the University of Western Ontario in LondonOntarioCanada.

The goal of our research is to understand how the brain controls voluntary movement, and how motor learning is achieved. Empirical studies using human subjects as well as theoretical studies using computational models and computer simulations are carried out to test hypotheses about how the brain controls movement.

We have published our first fMRI paper – we examined fMRI activation patterns as subjects observed other people making reaching errors in an externally applied force field (applied by a robot arm)

Malfait N, Valyear KF, Culham JC, Anton JL, Brown LE, Gribble PL. fMRI Activation during Observation of Others’ Reach Errors. J Cogn Neurosci 2009;  (in press)

PMID: 19580392

The basic finding is that part of the cortical network that has been shown previously to be involved in processing active reaching errors (when the subject themselves makes a reach error) is also involved when we observe other people making reaching errors.


Back in November, fed up with the slow speed and buggy implementation of Apple’s iDisk service via MobileMe, I decided to try Dropbox – a cross-platform (Windows, Mac, Linux) computer-to-computer sync service. In short: it’s amazingly good.

Once installed, Dropbox listens at the OS level for changes to files within your designated Dropbox folder. The instant a file changes (like when you hit “Save” in your word processor) it gets synced to the cloud (Dropbox uses Amazon S3), and then gets “pushed” down from the cloud to any other computer you have Dropbox installed on. Think push-email for your files.

The first time you set it up, it can take several hours to sync all your files up to the cloud … but once that’s done once, subsequent syncs are very very fast.

The other great thing is that Dropbox maintains a history of your files, so that if you want to go back in time to a previous version of a file (e.g. a manuscript) you can. It’s like a cloud version of Apple’s Time Machine.

Unlike Apple’s iDisk service through MobileMe (which is a similar idea), Dropbox is FAST, and stable, and “just works”. I literally never have to think about file sync or backup.

The other nice thing is that it’s cross-platform, so if you have a mixture of Mac / Windows / Linux machines, you can have your Dropbox folder synced on all three, all the time, plus automatic time-history of changes.

Anyway you can tell I really like it and I highly recommend it.


Here is a very nice summary of the history of PLoS, the origins and rationale behind PLoS ONE and its approach to scientific review and publishing, and some information about new article-level metrics designed to more objectively assess the “impact” of individual articles.

PLOS ONE: BACKGROUND, FUTURE

DEVELOPMENT, AND ARTICLE-LEVEL METRICS

Peter Binfield

Managing Editor, PLoS ONE, Public Library of Science

some excerpts:

PLoS believes that the journal in which an article is published should not be the primary mechanism to determine whether that article will have any worth. Instead, PLoS feels that each article should be evaluated based solely on its own contribution to the literature (and not on some halo effect due to being published in the company of other high-quality articles).

While of some utility as a predictive measure of the average impact of a journal, the Impact Factor has been widely misused to the extent that the careers and grants of many academics are influenced by the Impact Factor of the journals they have published in, and some academics are strongly discouraged from publishing in certain journals unless they have an Impact Factor. Moreover, because of the widespread adoption of the Impact Factor and the fact that a journal with an Impact Factor is liable to enjoy more subscriptions and receive more high-quality submissions as a result, journals and journal publishers have an incentive to promote the Impact Factor due to the potential content- and finance-related benefits that follow. Hence, the system is perpetuated by a combination of academia’s adoption of a poor measure and the industry’s support for that measure because of the commercial benefits it brings.
Although the Impact Factor is widely adopted within academia it is well understood that measurements of this type, applied at the journal level, are far from ideal when attempting to evaluate the scientific contribution of individual articles, or by inference, individual academics.

This is good news

LaTeX submissions now accepted at PLoS ONE

Good for PLoS ONE. I wish more neuroscience journals would accept LaTeX as well. It’s not like it hasn’t been around for a long time, and it’s not like it isn’t a standard in many other fields. I’m sick of dealing with bugs and crashes in MS Word (a.k.a. MS Turd) / EndNote and now Apple’s Pages and EndNote + Mathtype. Besides, LaTeX documents are all plain ascii files. What could be easier and less of a problem for future compatibility?


I think all academics (and all graduate students) should have formal instruction in:

  1. writing skills
  2. graphic design

After all, publishing papers and giving slide talks is all about communicating results. You all know how frustrating it is to fight your way through a published manuscript, trying your best to understand what the authors are trying to say… or sitting through a talk where even the speaker is fighting with his/her slides instead of the slides helping the speaker make his/her point.

Design Basics

I really like the following excerpt:

One of the biggest mistakes typical business people make with documents is going out of their way to seemingly use every centimeter of space on a page, filling it up with text, boxes, clip art, charts, footers, etc. Space, often called “white space,” is good. Embrace it. Use it. Often, the more space you don’t use on a page, the clearer your message becomes.

Sound familiar? Research grant applications, anyone?

Slides also suffer from this – I’m almost fed up enough that the next time I see someone click the next slide in a talk, and it’s literally a giant block of text, which they read aloud, I am going to get up and leave. (see this page of suggestions for slide presentations)

When we open up a new MS Turd document, or powerpoint presentation, we are faced with a zillion choices – what font? what size? italic? bold? both? colour? etc etc. The fundamental thing I take away from reading about graphic design and its importance, is that every choice we make must be based on a well thought out design strategy (or plan if you like that word better). If you are just selecting things at random or by “default” your work will suffer.

This is one reason I like LaTeX so much – it separates (mostly) content from design, and makes the design choices for you… based on well thought out design strategy.

Apple seems to have made some efforts to populate their newest iWork applications (Keynote for presentations, Pages for word processing & page layout) with “defaults” and especially Pages templates and Keynote themes that (I presume) are built by people with design backgrounds.

I think many scientists would say that design doesn’t matter … or that they don’t have time to worry about it … or that the priority should be content.

Think about it this way however: if good design (whether in a talk or in a grant proposal) will help facilitate getting your message across, and will also put the reader in a positive, relaxed, happy frame of mind, then shouldn’t you take advantage of this?

Good design will not compensate for a crappy message, especially in science … but crappy design will absolutely put up road-blocks for your audience.
