Chapter 13, Problem 56E

Explanation of Solution

Neuron and its pathway:

• A solitary cell, which is collectively available in the human brain to transfer the signals (chemical-based electrical signal), is known as a biological neuron.
• A human brain consists of billions of neurons to pass the signals.
• A series of connected neurons form a passage in the brain.
• Based upon the state of neurons, the strength of the signal has been classified.
• Neuron has two states, either excited or inhibited.
  • If a neuron is in an excited state, then it conducts a strong signal.
    • This leads to the formation of a strong pathway...
