Physical Address: We serve patients ACROSS SOUTH AFRICA. We have advisors covering the Eastern Cape and Garden Route . Our ...

Key cells in the brain, neurons, form networks by exchanging signals, enabling the brain to learn and adapt at incredible speed. Researchers have now developed a 3D-printed 'brain-like environment' ...

1 Motor Neurons A motor neuron’s cell body is ... Upper motor neurons generally begin in the brain’s motor cortex and interact with spinal interneurons to initiate the neural circuits that generate ...

Many stem cells in the developing brain mature into just one cell type, like a neuron or a support cell. Some can mature into two types. But these stem cells could mature into three lineages ...

Neuropathologically, these mice exhibit widespread tau pathology, affecting the cerebral cortex, hippocampus, brain stem ... of the lower limbs (paraparesis) develops by 5 to 6 months of age (Allen et ...

Published today in Frontiers in Neuroscience, the study fundamentally alters brain and nervous system medicine-giving doctors new clues as to why patients with motor neuron disease, multiple ...
