A healthy motor neuron needs to transport its damaged components from the nerve-muscle connection all the way back to the cell body in the spinal cord. If it cannot, the defective components pile up and the cell becomes sick and dies. Researchers at the National Institute of Neurological Disorders and Stroke (NINDS) have learned how […]

The Brain Is Less Compact Than Previously Thought

Using a technique that rapidly freezes the brain, preserving its true structure, scientists at Ecole Polytechnique Fédérale de Lausanne have shown that the brain is not as compact as has been thought. Typically, scientists must use electron microscopes to study the fine structure of the brain, including its connections between neurons, the synapses. But the […]
