The paper quantifies astrocytic sodium concentrations in mouse brain tissue and finds subcellular and cellular heterogeneity in [Na+] and NKA-mediated potassium uptake.

The paper shows that brief ischemia causes transient calpain-dependent disruption of axon initial segments in hippocampal granule cells, which can be prevented by blocking Na+/Ca2+ exchanger activity.

This study shows that short metabolic failures cause lasting increases in glutamate release, while longer episodes lead to postsynaptic transmission failure in hippocampal neurons.

The paper shows that astrocyte-mediated regulation of D-serine aligns with the BCM model of synaptic plasticity, explaining behavioral effects in mice and predicting new learning mechanisms.

The paper shows that astrocytic signaling via endocannabinoid receptors modulates dendritic integration in hippocampal pyramidal cells, enhancing spatial learning through frequency-dependent feedback.

The paper identifies a Na+ channel-dependent mechanism in hippocampal dendrites that contributes to spatial memory deficits in epilepsy and shows that targeting Nav1.3 channels can reverse these deficits.

The paper investigates region-specific properties of astrocytes in the visual layer of the superior colliculus, finding they have higher density, complex morphology, and closer proximity to synapses compared to astrocytes in other brain regions.

This study shows that dysfunction in grey matter NG2 glial cells affects neuronal plasticity and behavior, specifically impairing long-term potentiation but improving spatial memory.

This paper introduces a multi-threshold event detection algorithm for analyzing Ca2+ activity patterns across different experimental conditions and organisms.

The paper investigates glutamate spread in the neuropil using optical reporters and finds that glutamate can activate AMPA and NMDA receptors at distances up to 2 micrometers from the release site.

This study shows that LTP induces astroglial withdrawal, increasing glutamate spillover and inter-synaptic communication.

The paper constructs a realistic multi-compartmental astrocyte model to explore its biophysical properties and uncover features inaccessible through empirical methods.
