Pyramidal cells

Pyramidal cells are a type of nerve cell found in the brain, especially in the cerebral cortex and hippocampus. They have a pyramid-shaped body and long, branching extensions called dendrites, which receive signals from other neurons. Their long axons send signals to different parts of the brain and body. These cells are crucial for processing information, enabling thought, perception, and movement. Pyramidal cells are the main excitatory neurons—meaning they typically activate other neurons—helping coordinate complex brain functions like learning and memory.
