Insects have tiny brains inside their heads, but also have smaller brains called ganglia spread out across their bodies

Insect brains help them sense danger and feed faster, besides helping control their movement and orient them in space

Insect brains have many similarities to human brains, including a brainstem-like structure, two hemispheres, and a spinal cord equivalent
