The hu­man brain is the most com­plex ob­ject in the known uni­verse. Brain mat­ter is a cur­rent hot topic given that the US Govern­ment has a new ini­tia­tive pour­ing bil­lions of dol­lars into brain re­search. The­o­ret­i­cal physi­cistMi­chio Kaku blends sci­ence fic­tion with neu­ro­science and physics re­search in a dizzy­ing jour­ney through the pos­si­bil­i­ties of the fu­ture. Telepa­thy won’t be limited to read­ing minds but also will make pos­si­ble an “In­ter­net of minds” where one could just think about an­other per­son and in­stantly com­mu­ni­cate with them. These com­mu­ni­ca­tions could in­volve shar­ing ac­tual mem­o­ries down­loaded from a dig­i­tized brain sig­nal. Work­ing with dig­i­tized brain sig­nals has nu­mer­ous po­ten­tial med­i­cal ben­e­fits. Paral­y­sis vic­tims could op­er­ate pros­thetic limbs, de­men­tia sufferers could have their mem­o­ries re­stored, and with the help of nanobots in the blood­stream, a brain would know the bi­o­log­i­cal sta­tus of its body. In the dis­tant fu­ture the mind could be up­load­able. These are the tip of the ice­berg for what Kaku de­scribes in great de­tail. Don’t be in­tim­i­dated— he writes in easy-to-com­pre­hend lay­man’s terms. (sci­ence)
