And in a basket cell (above), axon branches, which allow the nerve cell to
send messages to other neurons, cluster densely around the cell body.
Action potentials, also known as nerve impulses, are electrical
messages sent from our brains
to other organs and muscles; for instance, nerves in the brain transmit action potentials through neural networks
to direct our arm muscles
to contract in order
to call into action our hands
to lift or hold an item, a primary research focus at the Columbia Motor
Neuron Center,
to which both the Zhang and Wichterle labs are affiliated.
