PROJECT TITLE :
Employing TDMA Protocol in Neural Nanonetworks in Case of Neuron Specific Faults
ABSTRACT:
Many neurodegenerative diseases arise from the malfunctioning neurons within the pathway where the signal is carried. In this paper, we propose neuron specific TDMA/multiplexing and demultiplexing mechanisms to convey the spikes of a receptor neuron over a neighboring path in case of an irreversible path fault existing in its original path. The multiplexing mechanism depends on neural delay box (NDB) which consists of a relay unit and a buffering unit. The relay unit will be realized as a nanoelectronic device. The buffering unit can be implemented either via neural delay lines as used in optical switching systems or via nanoelectronic delay lines, i.e., delay flip flops. Demultiplexing is realized by a demultiplexer unit consistent with the time slot assignment info. Besides, we tend to propose the utilization of neural interfaces in the NDBs and also the demultiplexer unit for detecting and stimulating the generation of spikes. The objective of the proposed mechanisms is to substitute a malfunctioning path, increase the quantity of spikes delivered and properly deliver the spikes to the intended half of the somatosensory cortex. The results demonstrate that vital performance improvement on the successively delivered number of spikes is achievable when delay lines are employed as neural buffers in NDBs.
