Neural Information Encoding.pdf

The brain is an electrical device that encodes, processes, and transmits information electronically, with neurotransmitters serving as messengers to transfer information between neurons. The sequence of action potentials contains the information, and electrical action potentials control the actions of neurotransmitters. The brain's electrical nature was appreciated since Luigi Galvani's work, but was later supplanted by the idea of neurochemical transmission. However, the demonstration that chemicals like acetylcholine can mimic nerve stimulation led to the conclusion that neurochemical intermediaries are involved in neural control. The logic of this conclusion is based on a syllogism, but this logic is flawed due to the Fallacy of Four Terms. Despite this, many still equate DBS with neurotransmitters like dopamine, but this is incorrect as neurotransmitters are merely messengers, not the message. DBS operates on a millisecond time scale, while pharmaceutical agents operate over minutes to hours, and cannot replicate the precise timing of information in the brain. The pattern of DBS is important for its therapeutic effect, and the time scale of these patterns is very different from pharmacological or biological agents.
