I semi-commissioned this artwork some time ago … you may have seen it on the wall behind me in zoom meetings. There is another (possibly even nicer) that will be revealed when I have had it framed. The artist, see below, is trying to drum up work to pay her school fees.

For nearly 60 days, Israel has blocked food from Gaza. Palestinians struggle to feed their families For nearly 60 days, no food, fuel, medicine or other item has entered the Gaza Strip, blocked by Israel.

For nearly 60 days, no food, fuel, medicine or other items has entered the Gaza Strip, blocked by Israel.

Aid groups are running out of food to distribute. Markets are nearly bare.

Palestinian families are left struggling to feed their children.

We are looking for an outstanding postdoctoral researcher to join our team at McGill University. The SjΓΆstrΓΆm lab studies neocortical circuits, with a focus on synaptic plasticity, NMDA receptor signaling, 2-photon optogenetics, and advanced 2-photon imaging. We are particularly interested in candidates with strong expertise in whole-cell patch-clamp electrophysiology and/or 2-photon imaging, and a solid track record of relevant publications.
Applicants should be experienced with whole-cell recordings and/or cutting-edge imaging approaches. Responsibilities will include performing experiments, analyzing and presenting data locally and internationally, writing manuscripts, and occasionally mentoring junior lab members.
Our lab is based at the Research Institute of the McGill University Health Centre, in vibrant, multicultural Montrealβ€”a city that offers exceptional quality of life. McGill and its neighbouring universities form one of the most dynamic neuroscience communities in the world.
For examples of our current directions, see:
β€’	Chou et al The Innovation 2025, www.cell.com/the-innovation/fulltext/S2666-6758(24)00173-5
β€’	Wong et al Neuron 2024, www.cell.com/neuron/fulltext/S0896-6273(23)00767-5
The position is fully funded with a competitive salary. Candidates are also expected to apply for external funding, for which we provide strong support. Opportunities are available for both Canadian and international applicants.
To apply, please send a Letter of Intent, CV, brief research statement, and contact information for three referees to Dr. Jesper SjΓΆstrΓΆm (jesper.sjostrom@mcgill.ca). In the subject line, include "Postdoc" followed by your name.
Application deadline: July 31, 2025.

πŸ§ͺ The SjΓΆstrΓΆm Lab in Montreal is looking for a postdoc! We study cortical circuits, synaptic plasticity, and NMDAR signalling using custom 2-photon microscopy and optogenetics. We seek candidates with strong patch-clamp and/or 2-photon imaging expertise, and a relevant publication track record.

Mehran collected mindboggling amounts of data and used many behavioural paradigms to get a holistic understanding of the function of median raphe cell types. Mehran will start his own lab in Oxford soon, watch out for this absolute neuroscience star!

Should you stick to your goal, try something else, or give up? Your median raphe nucleus in the brainstem knows and will decide for you πŸ˜‰. First foray of my lab into foraging, behavioural strategies and exploration. Amazing work from the one and only Mehran Ahmadlou: www.nature.com/articles/s41...

An exhibit that opened last weekend at Yale shows drawings from the influential duo Santiago RamΓ³n y Cajal and Camillo Golgi, recasting them as collaborators rather than rivals. It also reveals lessons for modern scholars.
