Being excluded and discriminated in science due to nationality is not unfamiliar to Iranian people. Getting single-entrance visa (or no visa at all), missing conferences, issues w using GitHub, Coursera etc! At least I should try to bring more awareness about it in the community
I am profoundly devastated.
Yesterday, we at

found out the organization cannot support participation of Iranian students, due to US sanctions against Iran.
This has left us heartbroken. This is the ugly reality of existing sanctions: online learning is not equal 1/

The Bernstein Network Computational Neuroscience stands by scientists of all nationalities who are discriminated against because of their nationality. We firmly believe that scientific discourse knows no borders but thrives through international exchange.
A fascinating study highlighting the importance of interaction between brain, metabolism, and immune system!
They showed lasting changes in a sensory system in aging are triggered by the gut and realized through the immune system (glia cells).
14/14 To conclude, we think, the brain has substantial, although unconscious, agency in choosing what to perceive, and doing so using internal actions that occasion dominance and switching.

This is a result of moving to a new vendor. In accordance with the guidance provided by the U.S. government, and not determined by GitLab, there are some countries that cannot access our platform. We apologize for the inconvenience this caused users.
ICE plans to deport intern'l students if classes go online in the fall. For Iranian students, this is painful bc sanctions already prohibit online classes in many fields. Public health & education shouldn't be restricted. Take Action👇🏽
