Communication of information between neurons is accomplished by movement of chemicals across a small gap called the synapse. Chemicals, called neurotransmitters, are released from one neuron at the presynaptic nerve terminal.
Follow Trail 12 until it runs back into trail 1 and familiar sights and then you are only about 200 yards from the great Cumberland Falls. To the best of my guessing ability I would say this loop was about 8.5 miles long which took us about 3 hours and 45 minutes.
From Blowing Rock to Asheville is about 100 miles along the Parkway and I enjoy this 100 mile section. Linville Falls visitor center (restrooms)... nice short (1 mile, relatively flat) hike to the very unique and beautiful water fall at the top of Linville Gorge.
