AbstractThe present paper deals with a fundamental issue in neuroscience: the inter‐neuronal communication. The paper gives a brief account of our previous and more recent theoretical contributions to the subject and also reports new recent data that support some aspects of our proposal on two major modes of communication in the central nervous system:

The seismic transmission volume
Geophysical Prospecting, 2001Parallels are drawn between phenomena observed in optics and typical characteristics in exploration seismology. Considerations are also made in the context of major physical theories throughout the centuries. It is concluded that the one key similarity between optics and seismics is the transmission volume, which has ‘fuzzy’ characteristics ...

The emergence of the volume transmission concept.
Brain research. Brain research reviews, 1998Interneuronal communication in the central nervous system (CNS) have always been of basic importance for theories on the cerebral morphofunctional architecture. Our group has proposed that intercellular communication in the brain can be grouped into 2 broad classes based on some general features of the transmission: wiring (WT) and volume (VT ...

Volume holographic imaging in transmission geometry
Applied Optics, 2004We address the performance of transmission geometry volume holograms as depth-selective imaging elements. We consider two simple implementations using holograms recorded with spherical and plane beams. We derive the point-spread function (PSF) of these systems using volume diffraction theory and use the PSF to estimate depth resolution. Furthermore, we

Glial cells and volume transmission in the CNS
Neurochemistry International, 2000Although synaptic transmission is an important means of communication between neurons, neurons themselves and neurons and glia also communicate by extrasynaptic "volume" transmission, which is mediated by diffusion in the extracellular space (ECS). The ECS of the central nervous system (CNS) is the microenvironment of neurons and glial cells.

Integration of wiring transmission and volume transmission
2000Publisher Summary Wiring transmission is the main form of chemical communication in the brain under most physiological conditions. However, substantial opportunity would seem to exist for the localized diffusion of transmitter, and transmitted-elicited signals, such as gases, to the releasing pre-synaptic terminal or to adjacent terminals within the ...

Sound transmission in the lung as a function of lung volume
Journal of Applied Physiology, 2002We were interested in how the transmission of sound through the lung was affected by varying air content in intact humans as a method of monitoring tissue properties noninvasively. To study this, we developed a method of measuring transthoracic sound transit time accurately.

Cell Volume Measurements by Optical Transmission Microscopy
Current Protocols in Cytometry, 2015AbstractCell volume is an important parameter in cell adaptation to anisosmotic stress, in the development of apoptosis and necrosis, and in the pathogenesis of several diseases. This unit describes a method for measuring the volume of adherent cells using a standard light microscope.

Brain motion and volume transmission: Keeping the interstice flowing
Medical Hypotheses, 2015Human brain undergoes two different kinds of movements: subtle pulsatile ones associated with the cardiac cycle and others of a greater magnitude related to breathing activity. These motions constitute a pumping force for the circulation of cerebrospinal fluid (CSF).
