Can you measure the speed of thought?

"Post-body-4163418078117126683"> As curious creatures, constantly examine ourselves and measure the speed of different things. With considerable precision, the researchers measured the speed of light, sound velocity, the speed at which the Earth orbits the Sun and so on. But what about the speed of thought? It seems instantaneous, but how long it takes shape?


First, to measure the speed of nowhere, it is necessary to identify the beginning and the final. To this end, thought will define how mental activity from the time when sensory information is received, and the time of the particular reaction. So thought includes the processes related to the perception (that determine what is in the middle, and whereabouts), the decision (to decide what to do) and planning procedures (how to). The identification of only one value for the speed of thought is like trying to identify a maximum speed of all forms of transport, from bicycles to rockets. There are several thoughts that can vary in terms of time. Take the quick reaction of a corridor that starts immediately after the sound of the whistle or the gun (which occurs in about 150 milliseconds) compared to the more complex decision of a driver should change lanes on the highway ( what occurs for several seconds to several minutes). Thoughts are invisible, and then you need to measure? Thought individual internal process that is difficult to investigate. Due to the interaction between complex neural networks distributed throughout the peripheral and central nervous system. Scientists, using functional magnetic resonance imaging and electroencephalography can see which parts of the brain are active during different thought processes and how information moves through the nervous system. However, we are not yet even close connection with those signals representing mental events. Many scientists believe that the best measure of the speed or efficiency of thinking is reaction time. This approach makes sense because express a reaction or procedures. And the reactions affect mainly three factors: distance - the higher the signal has to travel the longer reaction time. For example, the reaction of his legs is longer than the arms because the signal traveling to and from the brain needs to spend a longer
distance The characteristics of neurons -. Signals the broader faster neurons
transmitted Complexity - increase the number of neurons involved in thinking means absolute distance the signal has to pass, which means longer time answer. Moreover, most among neurons without physical contact, so that the signal is transmitted via neurotransmitters (molecules) traveling through small gaps between nerve cells called synapses. For all that more time (at least 0.5 milliseconds synapses) is needed. Although we are aware of our thoughts and movements or reactions resulting therefrom observed difference of 15-100 milliseconds at the time we think we have started the movement and the time when we really started. It is not clear why this happens, but it is believed that most people believe started the movement at the time the decision. These findings raise a number of important planning and control of our reactions issues, because obviously there is a difference between our decision to respond and our perception of the start of the reaction. Although you can not determine a single speed of thought, considering the time needed to plan and carry out the procedures allows valuable information on the effectiveness of the nervous system.
