Once again, my limited knowledge of neurology has been expanded. I used to think it was all about graded potentials, action potentials, neurotransmitters, and one way transmission of data from dendrite to axon to synapse..... I was always taught that the neuron was the main player in the transmission of messages. Now, after reading the Sciam article, it seems that the overlooked glial cells play a very big part in the transmission of data! It seems that data can travel BOTH ways up and down a neuron. It also seems that induvidual neurons are actually part of larger clusters that include Glial cells as part of the overall network. in short, it would seem that we have to go back to the drawing board when it comes to the understanding of how our brain functions, how we learn, and how signals are encoded and transmitted.
