In this manner, the signal passes at a steady rate, like a series of dominoes and is not slowed by electrical resistance This protects a giraffe’s toes just as much as a mouse’s nose The message is sped along even faster if the axon is coated with myelin It insulates like the plastic tubing of an el ...

Organization of the Nervous System
... A neuron is at rest when it is not sending a signal and is in a negatively charged state. Even at rest, the neuron allows K to pass. Neuron pumps 3 Na ions out for every 2 K ions it pumps in. At rest, there are more Na ions outside and more K ions inside Resting & Action Potential ...

How is the stimulus represented in the nervous system?
... Spike timing in the stimulus response can contribute to the representation in the brain. (1) Note the periodic responses at the frequencies of components of the stimulus (e.g. F1, F2, and F3 for the /da/ below). Using this information requires a central processor sensitive to temporal patterns. (2) ...
