The Olfactory Glomerulus: A Model for Neuro-Glio-Vascular Biology

The cellular basis of brain imaging is emerging as a new frontier in current neuroscience. In this issue of Neuron, Petzold et al. analyze a model system, the olfactory glomerulus, to show how neurovascular coupling involves an elaborate dance between axon terminals, presynaptic and postsynaptic dendrites, glial cells, and the capillary network.

A Computational Model of Neuro-Glio-Vascular Loop Interactions

We present a computational, biophysical model of neuron-astrocyte-vessel interaction. Unlike other cells, neurons convey "hunger" signals to the vascular network via an intervening layer of glial cells (astrocytes); vessels dilate and release glucose which fuels neuronal firing. Existing computational models focus on only parts of this loop (neuron→astrocyte→vessel→neuron), whereas the proposed...

[Neuro-glio-vascular interaction in ischemic brains].

The brain contains glial cells (astrocytes, microglia, and oligodendrocytes) and endothelial cells in addition to neurons. Under various pathologic conditions, the invasion of leukocytes such as neutrophils, monocytes/macrophages, and lymphocytes is observed. Interactions among these cell types play crucial roles both in brain function and dysfunction. However, the molecular basis of such inter...

Olfactory discrimination in the rabbit olfactory glomerulus.

Slow potentials evoked by odor stimulation were recorded from individual glomeruli in the olfactory bulb. Systematic analysis of responses to nine different, arbitrarily selected stimuli strongly suggests a certain amount of discrimination. This fact seems to reflect in the first synapse of the olfactory tract the type of discrimination that was recently demonstrated within olfactory neuroepith...

An energy budget for the olfactory glomerulus.

Energy demands are becoming recognized as an important constraint on neural signaling. The olfactory glomerulus provides a well defined system for analyzing this question. Odor stimulation elicits high-energy demands in olfactory glomeruli where olfactory axons converge onto dendrites of olfactory bulb neurons. We performed a quantitative analysis of the energy demands of each type of neuronal ...
