Final answer:
When researchers refer to a neural pathway as being 'stronger', it means that the pathway is better developed and more efficient in transmitting signals compared to other pathways.
Step-by-step explanation:
In the context of neural pathways, when researchers refer to a pathway as being 'stronger', they mean that the pathway is better developed or more efficient in transmitting signals compared to other pathways.
For example, in the brain, a neural pathway that has been frequently used or activated through learning or practice becomes stronger due to increased connectivity and efficiency of signal transmission. This strength can be measured through techniques like functional MRI scans, which show increased blood flow to areas associated with the pathway during cognitive tasks.
Overall, a stronger neural pathway indicates greater proficiency or expertise in a specific cognitive or motor function.
