Instead they have a set of ganglia (groupings of neurons) that distribute the control of the various parts of the snail.
The evidence shows slugs react to outside stressors, like salt, heat, electricity, and.

This is a clear example of evolutionary convergence, where vastly different. Put simply, we’re all using our brains.

This enables a network to form. Slugs don't have the large, complex, and highly. They have several pairs of ganglia connected to a nerve cord. Two studies published in the latest issue of science have revealed that birds, reptiles, and mammals have developed complex brain circuits independently, despite sharing.
Instead, it is spread throughout their body, with different parts. Their neurons (brain nerve cells) are surprisingly large (200 to 300 microns in diameter).
