Advancements in the treatment of spinal injuries could be the result of a significant discovery made by researchers in Canada.
The study, carried out by a team at the University of Alberta's Faculty of Rehabilitation Medicine, looked at neurons on the spinal cord which operate simple functions such as walking and bladder control.
Serotonin from the brain activates the neurons to perform functions and it was found that the serotonin receptors on the neurons were still active despite the absence of the hormone.
The discovery provides an important insight into the effects on the spinal cord after an injury, which is vital to developing useful treatments, according to the researchers.
However, it was found that the receptors are permanently switched on, which is thought to be a cause of spasms in patients and the next step is to look at ways of blocking these receptors to control the spasms.
Spinal injuries were highlighted recently at the Spinal Injuries Awareness Day in May, which raised awareness about the 40,000 people in the UK who have a spinal cord injury, according to the charity Aspire.
