Measuring a magnetic field is called the magnetoencephalogram or MEG. Measuring deep inside the brain with tiny electrodes deep is called intracranial EEG. Recording below the Dura, one of the three covers of the brain, is called ECoG, the electrocorticogram. Recording from the scalp is called EEG, or electroencephalogram. None of these measure individual neurons (which takes very advanced research techniques and is not generally practical), but rather account for the electricity in an entire brain region. Where does brain electricity come from and what does it mean? Measuring Electricity in the BrainĬurrent methods of measuring electricity in the brain utilize probes either on the scalp (the least intrusive method), below the skull coverings such as the Dura at the edge of the brain, and deep inside the brain. If consciousness in nature, and the human brain, is in the form of information, electromagnetic or otherwise, it is not clear yet how this could work. In fact, there are many different sources of electricity in the brain. Perhaps the oscillating brain waves are binding together information from specific regions.īoth utilize electricity in different ways. Perhaps the neuronal synaptic connections are involved in computation by summing the inputs in the network of connections arriving at the dendrite. Another theory of mind is that it consists of information, possibly in the form of electromagnetic energy, which would encompass all forms of electricity in the brain. The two major theories of how the brain generates the mind are the neuronal connections where electrical signals travel along axons triggering a chemical connection at another neuron’s dendrite ( see post Connectome) and electrical brain waves, which oscillate together at specific frequencies ( see post Brain Oscillations). Both of these mechanisms occur simultaneously, so, perhaps they are complementary and perform different functions. In this experiment it appears that synchronous waves are communicating information between two distinct brain regions with two different sets of neurons oscillating together at a specific frequency. When the content changes from color to orientation a different group of neurons have the same synchronous beta waves between two other regions. When the topic is color a group of neurons oscillate with synchronous beta waves between two brain regions.
