The conducting and processing capabilities of the human lumbar cord network and “spinal brain”

The spinal cord is part of the Central Nervous Systempresent in all vertebrates and for nearly two centuries, extensively studied for its anatomical, physiological and biological characteristics [1]. In the lecture we shall review the present status of neurophysiology in sensorimotor processes of the human lumbar cord involved in motor control when deprived from motor control, partially deprived and fully integrated. We shall explore the hypothesis that human lumbar cord isolated from brain control can respond to external sustained electrical epidural spinal cord stimulation with variety of tonic and rhythmical activity resembling “brain at the human lumbar cord” or in other words “spinal brain”. In addition, we shall address significance of the spinal brain capabilities for interpretation of complex descending input to the supplementary spinal brain in order to generate functional
