Pyramidal Neuron from Healthy Person : Neurons are electrically excitable cells in the nervous system that process and transmit information. They are the core components of the brain, and spinal cord and peripheral nervous system.Neurons are typically composed of a cell body, a dendritic tree and an axon. Studies have shown dendrite loss in individuals with depression.
Pyramidal neurons (pyramidal cells) are a type of neuron found in areas of the brain including the cerebral cortex, the hippocampus, and the amygdala. Pyramidal neurons are the primary excitation units of the mammalian prefrontal cortex and the corticospinal tract. Pyramidal neurons were first discovered and studied by Santiago Ramón y Cajal. Since then, studies on pyramidal neurons have focused on topics ranging from neuroplasticity to cognition.
