Skin blood flow and near-infrared spectroscopy

I definitely have to discuss the influence of skin blood flow on frontal lobe oxygenation measured by near-infrared spectroscopy here at Le Physiologiste …another paper from Ogoh’s group, in press in Eur J Applied Physiol, presents interesting results…

I will blog about it soon. In the meantime, go read the paper !

More to come…

It has been quiet around here for the last couple of weeks. Well, this last couple of weeks have been crazy!  Most of my time has been dedicated to grant writing and the preparation of my tenure package. I have submitted a first grant app to my Institution in mid-August, a second grant app to the Heart and Stroke Foundation of Canada (HSFC) at the end of August and a third grant app to the Canadian Institutes of Health Research (CIHR) no later than today. In addition, I also had a dangerously approaching deadline for my tenure package submission (September 16th). Well, it has been submitted an hour ago!

Unfortunately, I did not have a lot of time to blog…

I will start to live again since the next grant app deadline (Natural Sciences and Engineering Research Council of Canada) is in mid-November. In the meantime, I have at least two manuscripts to review, a literature review to write with a colleague and I am about to manage incoming manuscripts related to our research topic for Frontiers in Physiology.

This being said, I am preparing interesting posts related to cerebrovascular physiology and working on a series of posts, with guest bloggers, dedicated to cerebral oxygenation.

The next few weeks should be exciting at Le Physiologiste…stay tuned !
