Summary

The central nervous system uses two main communication methods: wiring transmission (WT) and volume transmission (VT). This study presents evidence for both, detailing their distinct roles in neural signaling.

Background:

The central nervous system (CNS) relies on electrochemical signaling for communication and computation.
Understanding the precise mechanisms of neural transmission is crucial for deciphering CNS functions.

Purpose of the Study:

To propose and provide evidence for two distinct types of electrochemical transmission within the CNS: wiring transmission (WT) and volume transmission (VT).
To elucidate the functional characteristics and experimental support for both WT and VT.

Main Methods:

Review and presentation of experimental data supporting the existence of two transmission types.
Analysis of the distinct characteristics of wiring transmission and volume transmission.

Main Results:

Experimental data supports the hypothesis of two distinct electrochemical transmission modes in the CNS.
Wiring transmission (WT) represents classical, direct neural pathway signaling.
Volume transmission (VT) involves chemical diffusion through extracellular fluid to distant receptors.

Conclusions:

The CNS utilizes both direct (WT) and diffuse (VT) electrochemical signaling pathways.
These two modes of transmission offer complementary mechanisms for neural communication and computation.
