Effect of potassium ion concentration on cultured sympathetic ganglia: conclusions about trans-synaptic modulation

Modulation of Synaptic Amplification in Sympathetic Ganglia

fabrication of new ion sensitive field effect transistors (isfet) based on modification of junction-fet for analysis of hydronium, potassium and hydrazinium ions

a novel and ultra low cost isfet electrode and measurement system was designed for isfet application and detection of hydronium, hydrazinium and potassium ions. also, a measuring setup containing appropriate circuits, suitable analyzer (advantech board), de noise reduction elements, cooling system and pc was used for controlling the isfet electrode and various characteristic measurements. the t...

Slow synaptic transmission in frog sympathetic ganglia.

Bullfrog ganglia contain two classes of neurone, B and C cells, which receive different inputs and exhibit different slow synaptic potentials. B cells, to which most effort has been directed, possess slow and late slow EPSPs. The sEPSP reflects a muscarinic action of acetylcholine released from boutons on B cells, whereas the late sEPSP is caused by a peptide (similar to teleost LHRH) released ...

The Effect of Endotoxin on Abdominal Sympathetic Ganglia.

The notion is an old one that diarrheas of infectious origin might be caused by the action of a toxin on the neurovegetative periphery. However, their site of action within the autonomic nervous system remains in dispute as does the importance which should be ascribed to this mechanism. Experimentally, Moreau (1868) produced what was called "paralytic hypersecretion of the succus entericus" by ...

Synaptic Transmission at Single Boutons in Sympathetic Ganglia.

Synaptic transmission has traditionally been studied at the level of the entire nerve terminal rather than at one of its constituent boutons. Autonomic ganglia provide preparations for recording from individual boutons, as well as for determining the calcium transients necessary for transmitter release at these boutons. The results suggest a new paradigm for synaptic transmission.
