The same can be asked of delusion, hallucination, addiction and so forth.Yes, there could be several anomalies [with genes, cells, and so forth] that maybe responsible. However, what are the closely responsible players that decide the configurations of disorder, away from order?All the evidence in neuroscience has said neurons are responsible for functions. But neurons with their electrical and chemical signals. So, since there has not been the possibility to build a mechanistic theory of neurons for functions, the next option is electrochemical.

Daphna Langer is building Voltify to transform freight rail energy systems. Instead of improving trains, Voltify optimizes energy as a managed layer, reducing costs and boosting efficiency. Backed by funding and recognition like Forbes 30 Under 30, the startup targets one of rail’s biggest inefficiencies: energy consumption.
