👉 Perforant is a type of nerve fiber that carries signals between neurons in the brain. It contains specialized cells called axons, which transmit electrical impulses and are involved in communication between different neurons. The fibers carry information from one neuron to another by passing through the axon hillock (also known as the "perforation" or "lumen") of a neuron. This process is crucial for transmitting signals and controlling various functions within the brain.
