Cortical output usually originates in layer V and layer III. Specifically, pyramidal neurons in layer V send output to subcortical structures and the spinal cord, while pyramidal neurons in layer III send output to other cortical regions. Layers II and IV are primarily involved in processing sensory input. Layer VI sends output to the thalamus.
