HUMAN BODY SYSTEM DIAGRAM : Biological Psychiatry, a journal that deals with the more nitty-gritty aspects of the brain, released an editorial this week that bears discussion. The article details the future of psychiatry based on advances being made in genetics today. I have actually written on this topic before but it is so important that I wanted to shed more light, given the new editorial. Brain Technologies - Part 1- Knowing your Genetic Fate A Word about your Genes First, I need to give you some very basic background in genetics. Our genes are basically blueprints that are housed inside every cell in our body (with the exception of a few special types of cells). Every cell has an identical copy of these blueprints that are stored in your DNA. Your DNA is made up of a long chain with a gzillion links, but there are only four kinds of links that make up the chain. Scientists use the letters A, T, C and G to represent the four kinds of links. A single gene can be thousands to milli...

Rat neurons attached to the scaffold (donut ring) and also sent axons (labeled with green Human fingertips a linear path to the brain with a “labeled-lines” structure. But new research on mouse whiskers from Duke University reveals a surprise — at the fine scale, the sensory system’s wiring diagram doesn’t have a set pattern. Human fingertips have several types of sensory neurons that are responsible for relaying touch signals to the central nervous system. Scientists have long believed these neurons followed a linear path to the brain with a “labeled-lines” structure.
