While the transmission of electrical signals across neuronal networks is a fundamental aspect of the operation of nervous systems, and this feature has traditionally been the main focus of computational neuroscience (Koch and Segev 1998,Dayan and Abbott 2001), neurochemistry adds many dimensions to the picture. For instance, it is now recognised that nitric oxide (NO) is a novel kind of neurotr...

Electrical activity has numerous roles in early neuronal development. Calcium transients generated at low frequencies regulate neural induction and neuronal proliferation, migration and differentiation. Recent work demonstrates that these signals participate in specification of the transmitters expressed in different classes of neurons. Matching of postsynaptic receptor expression with the nove...

We extend Shannon’s result on the capacity of channels with state information to multiple user channels. More specifically, we characterize the capacity (region) of degraded broadcast channels and physically degraded relay channels where the channel state information is causally available at the transmitters. We also obtain inner and outer bounds on the capacity region for multiple access chann...

Transmitter switching can provide resiliency and robustness to a communication system with multiple energy harvesting transmitters. However, excessive transmitter switching will bring heavy control overhead. In this paper, a geometric projection-based transmitter switching policy is proposed for a communication system with multiple energy harvesting transmitters and one receiver, which can redu...

The frequency assignment problem has been started from the discovery that transmitters, received the same or closely related frequencies, had interferences with one another. Nearly three decade back this problem has been modelled as a graph labelling problem. This labelling has several variations depending upon the type of assignment of frequency to transmitters. Here we shall discuss about som...
