An astrocyte bridge from synapse to blood flow
@article{Parri2003AnAB, title={An astrocyte bridge from synapse to blood flow}, author={Rheinallt Parri and Vincenzo Crunelli}, journal={Nature Neuroscience}, year={2003}, volume={6}, pages={5-6} }
Neural activity locally increases cerebral blood flow to deliver oxygen to working neurons. A new paper shows that astrocytes can detect activity at glutamatergic synapses via calcium changes in astrocytic endfeet and directly couple it to blood flow in vitro and in vivo.

Calcium Dynamics in Cortical Astrocytes and Arterioles During Neurovascular Coupling

This study supports the concept that astrocytic Ca2+ changes signal the cerebral microvasculature and indicates the novel concept that this communication occurs through the suppression of arteriolar [Ca2+]i oscillations and corresponding vasomotion.
Astrocytes act as signal transducer in neuronal activation and cerebral arteriole vasodilation
- BiologyJournal of Neurology
- 2003
A novel mechanism in which activated neurons indirectly trigger vasodilation through the coupling of astrocytes with these neurons and adjacent cerebral arterioles is suggested, which confirms the key importance played by the neuron-to-astrocyte signalling pathway in regulating local blood flow of cerebral arteriola.

Molecular Mechanisms of Astrocyte Vesicle Fusion at Synaptic Interfaces

It is shown that Syt7 and the synaptogenic factor Hevin are developmentally regulated and partially co-localise in cultured astrocytes, and this data suggest that SyT7 may regulate vesicular Hevin release from astroCytes, which in turn shapes how neuronal circuits develop.

Spatiotemporal Evolution of Functional Hemodynamic Changes and Their Relationship to Neuronal Activity

The spatiotemporal evolution of hemodynamic responses in rat somatosensory cortex to electrical hindpaw stimulation is investigated and results imply early microvascular changes in volume and oxygenation localize to activated neural columns, and that spatial specificity will be optimal within a 2- to 3-sec window after neuronal activation.

This work investigates an extended model of spiking neural P systems incorporating astrocytes and their excitatory or inhibitory influence on axons between neurons and can easily model Boolean gates like NAND-gates as well as discrete amplifiers.

Prostaglandins stimulate calcium-dependent glutamate release in astrocytes
- Biology, ChemistryNature
- 1998
It is shown that coactivation of the AMPA/kainate and metabotropic glutamate receptors (mGluRs) on astrocytes stimulates these cells to release glutamate through a Ca2+-dependent process mediated by prostaglandins, revealing a new pathway of regulated transmitter release from astroCytes and outlining the existence of an integrated glutamatergic cross-talk between neurons and astroicytes in situ.

It is reported that glutamate, in addition to its receptor-mediated actions on neuronal excitability, stimulates glycolysis--i.e., glucose utilization and lactate production--in astrocytes and is consistent with data obtained from functional brain imaging studies indicating local nonoxidative glucose utilization during physiological activation.
