Conclusions: Ponceau 2R-brilliant green double staining technique is a quick,simple and reliable myelin stain method in demonstrating the fasciculi in the central nervous system.
The fasciculus gracilis which carries sensory information from the lower trunk and legs, and the fasciculus cuneatus, which carries sensory information from the upper trunk and arms.
[Dr. Tan] There's a white matter highway between Broca's area and Wernicke's area called the arcuate fasciculus that can be communicates between the two.
Similarly, if you suddenly grab a vibrating cell phone, the sensation of vibration is carried from the nerves in the skin of your palm, via the fasciculus cuneatus, which is a collection of nerves all composed of 1st order neurons.
