cerebralganglia
Cerebral ganglia are clusters of neuronal cell bodies that serve as the brain in many invertebrates. They are typically located at the anterior end of the nervous system and can be described as the supraesophageal or cerebral ganglion, sometimes forming part of a multi-ganglionic brain. In different phyla, their structure and organization vary, but they generally function as central processing centers for sensory input and motor coordination.
In annelids and arthropods, the cerebral ganglia are connected to the ventral nerve cord by circumesophageal
Functions attributed to cerebral ganglia include integrating visual, olfactory, tactile, and other sensory inputs, coordinating locomotion
Terminology tends to be most common in invertebrate neuroanatomy. In vertebrates, brain organization is usually described
