The Nervous System

041 - Animal Nervous System
Paul Andersen begins this podcast with a discussion of brain lateralization and gives a brief demonstration of tests that were performed on split-brain individuals. He then discusses the major parts of a neuron and explains how action potentials are generated using voltage-gated ion channels. He explains how neurotransmitters transmit messages across a synapse and how these messages can be either inhibitory or excitatory.

    You mean the action potential? It's actually a bit different. The heart trace is a composite from the electrical activities from the various ventricles and valves of the heart. The heart trace looks quite different, but is similar in that it has an excitatory and refactory stage. The different peaks can tell you a lot about the different fuctions of the heart, like long QT. The peaks are named QRST in respective order and a heart with the long QT will take longer to go through the 4 peaks making it less efficient at distributing oxgyen to the body. Someone more qualified may explain this better, but I don't think the action potential is the same as the heart trace.

    Bailey Edwards The human brain is a interesting machine . Who know to what extend a person can manipulate the human body with the right conditioning and training or access the subconscious mind. I know some people who been training for years in such disciplines and technique's. They can control their heart beat and body temperatures and reset their sense of smell. When people get used to a smell they stop noticing it , They can also boost up the sense of smell and even able to push aside external distraction to more easily focus on sound and this makes them better at detecting lies. When people lie theirs a small shift in sound or variation for some people it is very slight almost unnoticeable for others it more bold and easier to detect. They keep trying to develop new disciplines and techniques to manipulate their own body and minds. I understand they are currently trying to mimic the effect of channeling electrical power through them without killing them. They heard about a man who is able to do it and are trying to mimic the effect. People sense accurate things about people all the time on a instinctual level. I wonder if its genetic or trainable. They do look very much alike.
