Limitations of the use of electrical impulses:
• Electrical impulses cannot be transmitted over long distances efficiently as they tend to lose strength.
• Electrical impulses require a point-to-point connection between neurons, making the process slower and less efficient in coordinating responses involving multiple body parts.
