This box is the âfeeder boxâ â where the worms will live and feed. Half fill the feeder box with the worm bedding. Make sure your bedding is moist but not wet. If you are using dry materials like straw or shredded paper, wet them first and then squeeze out any excess water.
Causes. There is no known single cause for autism spectrum disorder, but it is generally accepted that it is caused by abnormalities in brain structure or function. Brain scans show differences in the shape and structure of the brain in children with autism compared to in neurotypical children.
Interactions between the immune system and the nervous system begin early during the embryonic stage of life, and successful neurodevelopment depends on a balanced immune response. It is thought that activation of a pregnant mother's immune system such as from environmental toxicants or infection can contribute to causing autism through causing a disruption of brain development.
