It makes use of the normal food reserve stored in the interstices of muscular tissue, and; fasting or feeding, it draws upon this accumulation for support. The whole nervous system regains its energy by rest alone, but it maintains its substance at par by the means described. Hence, so long as there remain tissue and blood sufficient to carry on the work of the functions and of the circulation, brain and nerves must continue their directing task, and they cannot waste in the process.
