God reins element size, and comparing it artificial element
linear dimensions of neurons, neural cells and for these other nerve cells, are different from each other. Some nerve cells, with each other very closely grouped into a large group, and therefore, very short axons; while other nerve cells, transfer pulse in the distance between the body to be far portion, so that they may be linear length the length of the entire human body is compared. In order to obtain unambiguous and meaningful comparison, the comparison is a logical way to nerve cells acting portion acting portion and the through-Series Code ATC, transistors. For neurons, the role of the logic portion is a cell membrane, its thickness is about several times 10_5M meters. As logic er acting portion ATC is the gate-to-cathode distance is about several times to five pairs of transistors 10-1 cm 10_2 cm, this is the "touch-Jiu electrode" Ask distance, i.e. non-ohmic electrode - a "emitter" and "control electrode" a distance of approximately one third of the direct role of the environment of these parts, which is about the number of smaller Zhi. 1 T C T2 cm. Thus, the linear dimensions, a natural element than we are playing seize around the small element 1〇8 times.
Secondly, comparing their volume is also possible. Central nervous system occupied spatial gun, at about (in the brain) the magnitude of about one liter, i.e. 108 cm3. The number of neurons in the central nervous system included, is generally estimated rape 101G on a number of stages, or even more. Thus, the original volume of every nerve, can be estimated as 1〇 <cc.
