Recently, we discussed this insightful paper by Squadrani et al (2024) in our #JournalClub. It explores how #astrocytes enhance #SynapticPlasticity during #ReversalLearning by modulating D-serine levels, providing a #biophysical basis for dynamic #LTP thresholds. The findings suggest astrocytic signaling is crucial for #AdaptiveLearning, linking #glial activity to #behavioral flexibility. Here’s a summary from our JC:

Really cool detail on #perineuronalnets: Not only do the holes contain (stabilized) synapses, but those synapses are also tripartite - i.e. they are also contacted by Astrocytes. PNNs constrain the Astrocyte's leaflets, and prevent them from spreading off-synapse. This prevents glutamate spillover and mGluR activation.
Astrocytes require perineuronal nets to maintain synaptic homeostasis in mice

"We discuss preclinical evidence related to both neuronal & nonneuronal mechanisms that may be involved, touching upon the relevance of #interneurons, neuropeptides, & specific synaptic mechanisms in translating gamma stimulation into widespread neuronal activity within the brain. We also explore the roles of #microglia, #astrocytes, & the vasculature in mediating the beneficial effects of gamma stimulation on #brain function. Lastly, we examine upcoming clinical trials"
