Global Nernstian astrocytic depolarization breaks down during local synaptic input

The paper models astrocyte electrophysiology to show that localized potassium stimuli disrupt Nernstian behavior, with responses governed by conductance ratios and synaptic input specificity.

Mechanisms of perisynaptic astrocyte depolarization in response to neuronal activity

The paper develops a computational model to identify mechanisms of perisynaptic astrocyte depolarization, finding that NMDAR and GABAAR activation, rather than potassium/glutamate transporters, drive the phenomenon under physiological conditions.
