Between age 3 and 15, the human brain strengthens synaptic connections used often while those seldom used diminish. this supports the idea it’s best to focus on developing weaknesses it’s best to develop strengths as your synaptic connections are already strong we can change and develop effectively at any stage in life strengths are not very stable over time

The right answer is strengths are not very stable over time.

The construction of the cortex begins in the embryonic stage of the human being. Its development continues during its growth and does not acquire a fixed organization until the age of 10 years. But this cortical organization is likely to change according to environmental conditions. These structural and functional modifications are what is called brain plasticity.

This phenomenon of brain remodeling allows the adaptation of an individual to his environment.
