via massa intermedia
In about 70% of the people the thalamus is connected to each other by Interthalamic adhesion (massa intermedia, middle commissure, gray commissure).
Essentially this is an anatomical marker where the young thalamus fuses. The interthalamic adhesion (aka massa intermedia) is absent in most older brains. Therefore, it apparently has no major function in the brain.
