Motor system neurons not only control movement, they also incite action.
Cedars-Sinai has been awarded $11.99 million by California's stem cell agency to launch a clinical trial testing a potential gene and stem cell therapy for amyotrophic lateral sclerosis (ALS).
Some neurons have the ability to detect and compensate for neighboring neurons, while others do not. The findings shed new light on synaptic plasticity.
A new study challenges the popular theory of intrinsic, dynamic patterns control motor behaviors. Researchers found neuron population dynamics in the motor cortex are different during reaching and grasping behaviors.
Study reveals a self-corrective mechanism within synapses that is activated by neurodegeneration and slows disease progression in animal models of ALS.
Researchers combined intact neurons from a rat's spinal cord with a tissue-engineered 3D muscle system, creating a biohybrid robot, or biobot. After culturing the system for seven days, the motor neurons from the spinal cord produced electrical activity, causing contractions in the artificial muscles and mimicking the behavior of the peripheral nervous system. The findings could have positive implications for the treatment of neurodegenerative disorders that affect motor control.
The TBK1 gene regulates the disease progression of ALS in mouse models of the neurodegenerative disease. Loss of the TBK1 gene in motor neurons increases SOD1 aggregation and accelerates the onset of the disease.
