[My friend Shin, JA1NUT, writes a very interesting item on his blog. No wonder at age 73, my thinking remains quite sharp! Posted by Layne AE1N]
“It is interesting that diffusion tensor imaging technique shows the increased integrity and development of neuron fibers in the brain. This study shows learning Morse Code has augmented the fractional anisotropy of the Inferior Longitudinal Fasciculus whose function is vaguely understood regarding emotion or thoughts. It means learning Morse Code has caused alteration of this structure of white matter, that is, increased connection of centers in occipital, temporal lobe and the other areas.
Reading only this abstract of the paper, I am wondering how they have set the control in the observation of time-dependent change. The other question is if learning Morse Code could be compared to second language acquisition. Since Morse Code system has no grammar, it is not a language itself.
Despite such questions in this study, it still means Learning Morse Code causes a structural change in the white matter, which means the improvement of the skill in Morse Code reception will be done stepwise. Once we obtain its capability, we won’t lose it easily. Morse Code reception could be useful to activate our brain.”
