A fork cell, also known as a fork neuron, is a type of neuron found in the human brain, located in the anterior cingulate cortex (ACC) and frontoinsular cortex (FI). [1] This type of neuron is characterized by its own morphology - two primary apical dendrites, giving them a distinctive 'forked' appearance. [2] Fork cells are found in humans and some other highly evolved species. [1] [3]
