Neurons with Surprising Properties
Just when scientists thought they had a pretty good understanding of how neurons communicate, along comes a new set of seemingly abnormal data that overturn the official paradigm (such upheavals are not uncommon in the world of science). Any good neuroscience textbook will tell you that neurons are stimulated or inhibited by input signals that they receive through the synapses between their dendrites or cell bodies and other neurons. As a neuron receives all these signals, it integrates them, and then fires one or more action potentials into its axon. These action potentials travel down to the tip of the axon, where they cross synapses to other neurons, and so on.
But as a team of researchers from Northwestern University, in Illinois in the United States, discovered and reported in the February 2011 issue of Nature Neuroscience, the process just described is clearly not the only way that nerve impulses travel through neurons. (more…)
