Morphology controlling signal

Organs and Tissue have a variety of morphology.
On them, various biological signals are affected by the morphology.
We investigate the effect of morphology on the biological signal transmission.
A example of signal transmission through complex morphology is a neuronal signal passing through the surface of brain.
The neuronal signal is scattered by the complex morphology as shown in the below figure and thereby is processed.
