The 10% of Brain use myth is debunked by an argument that presupposes that the purported myth refers to the number of neurons that are active or that we know what percentage of the total neuronal capacity there is. First we do not have a way to determine how many neurons, of the total population of neurons* are firing at any given time nor do we even know what the total capacity of one neuron is beyond the knowing that the neuron can have up to approximately 10000 synapses**.

For that matter we've been assuming that there were 100B neurons in the brain based on cortical samples and the latest method of counting neurons reveals 86B vice the earlier estimate of 100B. Plus out brain activity measures using Electroencephalography requires thousands to million of neurons firing to register a signal***. So current methods of measuring brain activity is still lacks precision.

All parts of the brain are utilized **** but to what degree? Obviously under normal circumstances the percentage of utilization of any one part of the brain would not be anywhere nears 100% or we would all become dysfunctional under high levels of physical stress instead of our usual response of hyperactivity when under threat.

So there is a lot of discussion and hard research that needs to be accomplishes before we can accurately determine what percentage of the brain we utilize for various conditions and situations.
