To visualize the neural pathways, two markers (red and green) were applied to two regions of the orbitofrontal cortex. These compounds then migrated, accumulating in the thalamic neurons.

When faced with a change to our environment, we have to make appropriate decisions, which usually involves the orbitofrontal cortex. Yet unexpectedly, scientists have discovered that a brain region located in the thalamus also plays a crucial role in using these evolved skills.

Using a labeling technique, the scientists evidenced a specific area, the thalamic submedius nucleus, which is closely linked to the or...
