Debunking the 10% Brain Myth and Plant Consciousness

The [idea][1] that humans only use 10% of their brain [capacity][17] has been [previously][4] debunked as [untrue][5]. The brain is [complex][7] and we use a greater [degree][2] of it than we realize. [However][13], there are still many things we don't understand about it. One of the things we do know is that the [brain][15] communicates through [electrical][3] signals. This is how we are able to think, feel, and move. Scientists have [claimed][10] that plants have a 'brain-like [command][11] center' in their roots, [possessing][9] a nervous system [similar][14] to animals. This [article][6] argues that this is not the case and that the workings of a plant are [greatly][8] different from that of an animal. While plants do [communicate][12] through electrical signals, the signaling is only [superficially][14] similar to that of a [complex][7] animal brain. [Investing][17] energy in a system that can feel [pain][19] would be a poor evolutionary strategy for plants, [according][20] to the article. Plants cannot run away from danger, so such a system wouldn't be advantageous. While the workings of the brain may be [simplified][11] to an array of electrical pulses, the [mass][16] of cells in a plant is not enough for consciousness to evolve.
