THE NERVOUS SYSTEM IS NOT A COMPUTER NETWORK
 
BRAIN
COMPUTER
Information travels in Meters/sec.
Processing speed measured in Hz.
Main processor has dynamic connectivity.
Most processing uses analog transients.
Electrical power provided by Ions & O2.
Peripheral Input & Output Devices are Standard, Elegant ‘Plug & Play’ Devices.
Memory upgrade requires learning.
‘Hardware’ is Soft & Pliable (Protect It!)
This processor has created the one on the right to help us do more and do it faster.
Information travels close to speed of light.
Processing speed measured in MHz or GHz.
Main processor connections are hard-wired.
Most processing uses digital 1s and 0s.
Electrical power is external AC or DC source.
Peripheral Input & Output Devices are ‘extra’
  and too often are ‘Plug & Pray’ Devices.
Memory upgrade requires new components.
‘Hardware’ is Rigid and Stiff (Do Not Bend!)
This processor has been created by the one on the left (for better or worse).
Both utilize electrical currents in an elegant fashion
