According to the latest research, when we touch the object we hold, we can determine the exact position of contact on the object in addition to the changes when we feel the pressure transferred to the finger Even if we do not directly touch the body, our brain can also detect the position of touch The tool we hold is almost like an extension of ourselves The results of the study are published in current biology https://doi.org/10.1016/j.cub.2019.10.062 In more than 400 tests, more than one study participant held the wooden pole, felt and determined the position of the two strokes on the pole In addition, the researchers used electroencephalogram (EEG) devices to record participants' brain activity The results showed that 96% of participants recognized two touch correctly, and the brain uses similar neural mechanisms to detect the feelings on our own skin and the objects we hold Hypothetical neural mechanism for sensing the touch position on the skin and tools
