Haste and waste on neuronal pathways
This news release is available in German. To write this little piece of text, the brain sends commands to arms and fingers to tap on the keyboard. Neuronal cells with their cable-like extensions, such as axons, transfer this information as electrical pulses that trigger muscles to move. The axonal signal speed can be to up to 100m/s in myelinated axons along the spinal cord.
For a long time, scientists assumed that axonal signal conduction is by and large digital: either there is a signal, "1", or there is no signal, "0".
Strong propagation speed variations
