The scientist looked around before answering, as if to make sure no one else could hear. “Well,” he said, almost apologetically, “I have sometimes seen waves of excitation slowly propagate across the brain in patterns that do not correspond to any known axonal pathways.”
Nevertheless, hints that the brain might work in ways not contemplated by “normal” neuroscience have emerged over the years. Here are a few examples.has it that neurons transmit information to one another in one of two ways: release of neurotransmitters in synapses that connect one neuron to another or through ionic electrical conduction across “tight junctions” binding the membranes of different neurons together.
Although MEGs offer more precise, localized representations of brain activity form the scalp than EEG’s, they too are considered epiphenomenona in the sense that the brain doesn’t actually transmit and process magnetic information in order to do what it does.play a role in neural information processing. A wide variety of animals, such as birds, are known to use the Earth’s magnetic field for long-distance navigation, possibly through nano-crystals of iron compounds that form in some neurons.
