The Soybean Car was actually a plastic-bodied car unveiled by Henry Ford on August 13, 1941 at Dearborn Days, an annual community festival. The frame, made of tubular steel, had 14 plastic panels attached to it. The car weighed 2000 lbs., 1000 lbs. lighter than a steel car.
The second brain contains some 100 million neurons, more than in either the spinal cord or the peripheral nervous system, Gershon says. This multitude of neurons in the enteric nervous system enables us to feel the inner world of our gut and its contents.
Later, during life, a relatively small number of new cells will be added in several parts of the adult brain related to memory and learning. Amazingly, each of the remaining neurons can connect with up to a hundred thousand other cells. This number of connections is a truly enormous number: 10 thousand trillion. Even further complicating this picture is that these connections occur in many different ways, including different placements on neurons, as well as connections with the larger number of other brain cells that arenât neurons.
