De temps en temps, dans cette vie pourtant parfaite, il se sentait embrassé par une solitude adipeuse. La tristesse se lançait alors à son ascension jusqu'à ce qu'il fonde en larmes et sanglote pendant de longues heures. Pendant ces crises passagères, l'ensemble de ces robots domestiques se regroupait autour de leur humain défaillant et attendait la fin de ce que leurs programmes classaient comme "défaillances neuronales". Au petit matin, la vie reprenait.

#GoeMe23: Let's talk about the versatility of #biointerfaces for your research!

Biointerface technologies promise label-free, functional recording of #neuronal activity for #organoids, acute tissue slices, and primary cell culture.

We are excited to be exhibiting our innovative technology at The 15th Göttingen Meeting of the German Neuroscience Society.

Come by booth Nr. 18 to chat about #functional recording, #phenotypic screening, #connectivity, and much more!

Really enjoyed this perspective on how we could make #neuromorphic #computing work in the future!
There is an exciting possibility that after decades of studying #neuronal #circuits and their #dynamics out pure curiosity (for the most part), we could start translating what we have learned about signal dimensions and information routing to #hardware systems. This could trigger a big change in #AI as well.

Why are #Autistic people really quick in some respects and slow in others? Why do we have a thought process that seems scattered much of the time, but give us a problem to solve and we'll do it in record time?

This article points to possible answers to some of those questions. Has to do with #Neuronal connections in the #Brain .

New #introduction for neuromatch.social 🙂​

My group investigates and defines cell types and neural circuits of the #thalamus, #hippocampus, and #cortex that contribute to spatial #memory processes.
These processes break down in #Alzheimer's disease. To understand the causes/triggers of #neurodegeneration, we study early-stage #Tau #pathology in the human #brain and in mouse models.

I previously defined various types of retinal ganglion cells using ex vivo #patchclamp recordings during my PhD in #Basel, before moving to #Oxford to work on #GABAergic #neurons of the #hippocampus, followed by the #medialseptum. My favourite technique is in vivo #extracellular recordings and #juxtacellular labelling as it enables identification of single #cells based on their firing patterns, #axon terminal distribution, and #neurochemical profile.

As an #experimentalist, my expertise is primarily in vivo #neurophysiology and #neuroanatomy. I am also interested in #consciousness, the origins of #memory, and regulation of #neuronal activity and #behaviour by #neuropeptides.

And realized I did not provide an #introduction. I am a professor and chair of #phamacolgy and #toxicology at the #Universityofutah where I study #epilepsy. I focus on therapy development and the role of #glia in #neuronal hyperexcitability. I lean very much to the #left. I support the #LGBTQ community and my family members. I adopt dogs from shelters. #BLM. I #hike the #wasatchmountains for peace and quiet and especially love the #desert and #oregonbeaches.

klingt sehr spannend. "We evaluated the effect of Kdm6a-KD on Ngn3 expression, a bHLH transcription factor regulating neuronal sub-specification in #hypothalamus. Kdm6a-KD decreased Ngn3 expression in females but not in males, abolishing basal sex differences."
