Centipedes possess a decentralized nervous system, with a brain composed of two or three pairs of ganglia and a ventral nerve cord with segmental ganglia. This system allows for independent control of individual legs and body segments, even when the brain is removed, as demonstrated by experiments where centipedes can still walk and respond to stimuli after being de-cephalized. Research suggests that central pattern generators (CPGs) play a crucial role in generating locomotion patterns, with sensory feedback and descending control from the brain also influencing movement.

“To the extent it is used I fear it’s often for illicit finance. It’s an extremely inefficient way of conducting transactions, and the amount of energy that’s consumed in processing those transactions is staggering,” the former Fed chairwoman said. Yellen’s comments have been cited as a reason for bitcoin’s recent losses. However, Yellen’s assessment of bitcoin as a inefficient medium of exchange is an important point and one that has already been raised in the past by bitcoin bulls. Using a volatile asset in exchange for goods and services makes little sense if the asset can tumble 10% in a day, or surge 80% over the course of a two months as bitcoin has done in 2021, critics argue. To put a finer point on it, over the past 12 months bitcoin has registered 8 corrections, defined as a decline from a recent peak of at least 10% but not more than 20%, and two bear markets, which are defined as falls of 20% or more, according to Dow Jones Market Data.
