It’s a real shame that folks with mental illness have to fight not only their symptoms but also concerted efforts to undermine their treatment. 😢 The @nytimes.com mag published a long piece entitled “rethinking adhd”. Here is a 🧵 highlighting its factual & logical errors 1/n

If you have been affected by the fires in LA, or are concerned about your ability to keep precious Drosophila strains going during the latest funding crisis, we will host your strains as a backup. Please email me. Please amplify. If you are also able to host fly strains, add your name as well.

It does matter to continue to try to elicit shame to prevent the 'rhinoceros stampede' from 'destroying the habitat for democracy.' _________________________________________ ¹ Rhinocerization is Hungarian playwright Eugène Ionesco's term for losing your empathy and becoming a nationalist minion.

There are many nuances regarding the structural neural plasticity associated with antidepressant drugs. 💊🧠 We share our thoughts here in a Nature Reviews Neuroscience article, led by Clara Liao with co-authors from Conor Liston’s lab at Weill Cornell. www.nature.com/articles/s41...

New Paper Alert! 🚨 "Testing methods of neural systems understanding" by me & David Bau is online now: www.sciencedirect.com/science/artic… We argue for an explicit test of the tools used to understand 'neural systems', i.e. brains and artificial neural networks.
Highlights

    •

    Neural systems have a variety of features that make them difficult to study.
    •

    To make progress in understanding biological and artificial neural systems, an explicit test of the analysis tools according to a clear measure of success should be carried out.
    •

    We purpose ‘experimentally-validated understanding’ as a testable goal and argue methods should be tested on artificial neural networks.
    •

    We summarize methods from neuroscience and interpretable AI that can be explored.
