Descending activity from the brain shapes spinal cord function throughout life(Ann Rev Neu-rosci 24:807-843,2001),yet the pathways and the processes through which this activity inducesand maintains spinal cord plasticity are poorly *** are using a simple conditioning modelto explore these pathways and processes.
