Autistic children have fewer “trees” in their brains than normal people
Imagine a giant tree, as big as a giant rain tree. It has many branches, spreading out in all directions. This is called the Purkinje cell.
The cells you are referring to are called Purkinje cells. They are the largest neurons in the human brain.
They are located in the cerebellum.


The Purkinje tree is a large neuron in the cerebellum. It receives information from other parts of the brain and sends signals to the cerebellum. The cerebellum then uses this information to control movement. But in children with autism, the Purkinje tree is smaller and less active than usual 24-50% .
This can lead to problems with movement, such as coordination and balance difficulties.(The red lines in the image represent nerve fibers. The image on the upper right shows that a typical child has almost twice as many nerve fibers as the autistic child in the lower right image.)

The cerebellum is responsible for many things, including:
The things we learned are about balance, movement, muscle coordination, learning new movements, swimming, riding a bicycle, somersaulting, etc.
*** What we don’t often know is that the cerebellum also controls learning, attention, language, emotions, surprise, hearing, listening, pronunciation, vision, and thinking. Therefore, in autistic children or children with cerebellar atrophy, it is easy to have the above problems. Inhibition is also reduced.
But the brain has the ability to develop and adapt itself, which is called plasticity. The brain can stretch and shrink like plastic. Therefore, TMS stimulation of the cerebellum and other parts of the brain + developmental training is very important. It allows the tree to expand its branches and leaves.
