Yes, this is true because of neuroplasticity. When you make new connections between neurons, these connections are continually strengthened each time you make the connection. The way your brain functions along with its structure are consequently altered by these new neural connections. The anatomy is fixed. Like the hardware on your computer. With 85 billion microprocessors (neurons) and ten trillion wires and connections (dendrites and synapses), new pathways are used, stored, accessed, etc. The hardware is factory issued. The software is intelligent. The operator decides how to use the software. The software is highly variable.
