The cockroach is the insect that possesses 11 "mini-brains" or clusters of neurons that act as functional units, allowing them to perform tasks with a decentralized nervous system. This unique feature helps cockroaches to survive and adapt in various environments.
A Brain?
No, because the insect will find the diaphragm of the ear in its way. Since this diaphragm is made of cartilage,and covers the whole cross-section of the ear-canal, the insect will not be able to enter the brain.
No, it won't.
a insect eye can go at a 360 angle that a human eye can't and the insect brain receives many images and the human eye receive information and send it to our brain along the optic nerve
