Moreover, seasonal light changes were also found to alter numerous neurons in the paraventricular nucleus (PVN)– another region of the brain that is critical in controlling stress, growth, metabolism, reproduction, and immunity.
“The most impressive new finding in this study is that we discovered how to artificially manipulate the activity of specific SCN neurons and successfully induce dopamine expression within the hypothalamic PVN network,” Dulcis explained.
In other words, the researchers believe their study is groundbreaking because it provides a novel explanation of how the brain reacts to seasonal light changes. Plus, equipped with these findings, scientists now have an actionable target to offer new treatments for disorders associated with seasonal light exposure changes.
