Note: Some students might have trouble discussing this topic because they may have a family member with Alzheimer's disease. Model a nerve cell. Explain to students that the nervous system functions ...

Among all the bad things that can happen to the brain when it is severely jolted - in a car accident, for example - one of the most common and worrisome is axon damage. Axons are the long stalks that ...

Two research groups in Asia have identified an enzyme that governs whether a neural projection becomes an axon or a dendrite and several of its upstream and downstream targets. Their findings on the ...

This image shows the researchers' subcellular-sized devices, which are designed to gently wrap around different parts of neurons, such as axons and dendrites, without damaging the cells. The devices ...

Scientists report that halting production of synaptotagmin 17 (syt-17) blocks growth of axons. Equally significant, when cells made more syt-17, axon growth accelerated. A wide range of neurological ...
