The beginning of a new era for our research group

You remember that discussion about the need to monitor more than one cerebral artery in future studies (here and here) ?

Well, today is a good day ! This is the first sight that I got when I arrived at my office this morning…

photo[1]A box from DWL USA ! Yes today is the beginning of a new era for our research group ! We now have our second monitoring probe !

photoRegional differences in cerebral autoregulation, cerebrovascular vascular reactivity to CO2, cerebral SNA, distribution of blood flow during exercise…

We can now join the party !

On the need to monitor more than one cerebral artery in future cerebrovascular studies…Part 2

In a previous post, I was asking myself if it would still be possible to monitor blood flow/blood flow velocity in only one cerebral artery in upcoming studies, taking into consideration recent publications suggesting regional differences in cerebral blood flow distribution during exercise, cerebral autoregulation and cerebrovascular reactivity to CO2…

I think that it is easy to know on which side of the fence I stand regarding that issue…

Well, I just bought another monitoring probe in order to be able to study both the anterior and the posterior cerebral circulation. Although I discovered only recently that we can do a lot more than I thought with only one probe, I still consider that it will more and more difficult to keep our head in the sand (as an investigator and a reviewer) in light of all this new information related to regional differences in cerebral blood flow regulation.

Exciting times ahead of us !

We have winners here !

Last week, we had our annual “Scientific day” at our Research Center. Two grad students (one student from my team and one student I am collaborating with) with topics related to cerebrovascular physiology had a poster presentation.

Olivier Le Blanc presented data on dynamic cerebral autoregulation in endurance athletes


Simon Malenfant presented data on the influence of pulmonary artery hypertension on dynamic cerebral autoregulation


Both have done very well and even won a prize for their presentation.

Congrats guys !
