Expert Answer:

- When we talk, our vocal card generate sound and we all know that Sound is a form of energy.
- Hence energy from our body is utilized for the vocal cord to do some work so that sound energy is generated.
- The same happens while we are thinking, complex cells in our brains transfer information and these cells interact with each other.
- For this stimulated activity, the cells need energy that we gain from the nutrition. 
- This causes the brain to get some additional blood flow towards itself, hence to get additional blood flow while thinking, we need energy.
