🧠🎨 New paper by Meyer et al: #astrocytic #sodium #homeostasis is not uniform. Using multiphoton #FLIM in #mouse #brain slices and #invivo, they show strong #cellular and #subcellular heterogeneity in astrocytic Na⁺ levels.

Processes contain more Na⁺ than somata, Na⁺ varies between #astrocyte branches, and distinct Na⁺/K⁺-ATPase subunit patterns help tune local K⁺ uptake and #glutamate-linked Na⁺ influx.

Intravital calcium imaging of meningeal macrophages reveals niche-specific dynamics and aberrant responses to brain hyperexcitability

Intravital microscopy of meningeal macrophage Ca²⁺ dynamics reveals previously unknown population heterogeneity, vasomotion-coupled activity, and diverse responses during steady state and neuroinflammatory conditions, offering relevant insights into brain immune regulation.

@aheadofthenerve Super nice, thanks for this excellent preprint and explainer thread!
If you don't mind me asking, how do you think this switch in population code is triggered? Is it just a change in excitatory input patterns to CA1 that overrides an otherwise active place cell network? Or also a change in neuromodulatory input (e.g. dopaminergic burst or so)?

If ok I'd also add some hashtags for greater reach:

2,3-Bis(acetylmercaptomethyl)#quinoxaline (BAMMQ) is an #antiviralAgent which inhibits #poliovirus #RNASynthesis #inVitro and #inVivo and inhibits #humanHerpesvirus1 multiplication in vitro. It does not interfere with attachment, penetration or #DNASynthesis, but interrupts a late stage in virus assembly and/or maturation. BAMMQ was first identified as an antiviral agent in 1974, when it was shown to inhibit poliovirus growth by 99.8% or more at concentrations as low as 10−5 M. That same year.
