Patients with Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, tend to have difficulty understanding and using verbs that denote actions. Scientists have hypothesized that this is due to damage to the motor system, but a recent study by Liuba Papeo, neuroscientist at the CIMeC in Trento, and her team have found that this is not the case. Their research suggests that there is no causal relationship between an individual’s motor deficits and difficulty with verbs. Read the news story or study in Cortex.
