The process was discovered during Rolls's studies aimed at deciphering the inner workings of dendrites -- the part of the neuron that receives information from other cells and from the outside world. The research will be published in the print edition of the scientific journal Current Biology on 21 December 2010.
The purpose of the nervous system is to transfer information from the PNS to the CNS, process the information in the CNS, and send back information to the PNS. This transfer of information from the external environment, through neurons, and back again to the external environment is known as neuronal signaling.A summary of neuronal signaling: Before a neuron receives a signal, it is in a resting state Neurons receive signals in two forms: Chemical changes.This is done via neurotransmitters (see Synaptic Transmission below) or chemical elements in the environment (e.g., olfactory receptors) Physical changes.he purpose of the nervous system is to transfer information from the PNS to the CNS, process the information in the CNS, and send back information to the PNS.
