This is the electrical signals that run along the neurons in your brain and body in general, constantly relaying information back and forth throughout the whole complex machine. Without it we would be like plants, with one part of our bodies completely unaware of what`s happening to the rest of it, and animal life as it is familiar to us would be entirely impossible.

have, I expect, heard of the notion of electrical signals running throughout our bodies (it`s why the machines built the Matrix, right ), but few will actually know what that means. In today`s post I`m going to be talking about what neuronal signals actually are, and so explain why being hit by lightning is a bad thing but beingdefibrillated (like in ER) can be a good thing. Your body is anintricatelywired piece of equipment - neurons connect every part to every other via the nervous system. In my last post in this series, I discussed how cells talk to one another; well the role of the nervous system is to allow tissues to talk to one another. This is often dictated by the central nervous system, made up of the brain and spinal chord, which is obviously vital for any concious decisions you might want to relay to the rest of your body, yet the majority of the signals coming from the brain are completelysubconscious- regulating the conditions of your body, for example. The peripheral nervous system, made up of all of the non-CNS neurons, tends to be less involved in the decision making, and more acting as a simple relay of information; either sensory signals working their way back to the brain, or important instructions being handed down from the CNS to the peripheral tissues like muscles. This entire network is dependent on a single family of cells: neurons. These are a highly-specialised type of cell that have evolved...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
