A neuron is a cell that communicates information along electric pathways. When you learn something new, your neurons have to build new pathways.

What is the implied meaning of the word pathways in the sentences above?

Channels between brain cells, passing along nutrients to improve thinking skills
Connections between brain cells, through which information can travel
Channels between brain cells, where electricity activates more cells to grow
Connections between brain cells, allowing them to share water and minerals

I believe the answer is: Connections between brain cells, through which information can travel
