“Serotonin, in particular, plays a crucial role during early brain development by helping neurons grow and connect properly. When BPA disrupts this system, it alters the formation of key brain regions like the cerebellum, which is vital for coordination and cognitive processing.”

“Using mice that carried a mutation that blocked Mfsd2a's capacity to transport DHA, the investigators assessed blood-brain barrier function as well as caveolae formation and activity in the animals' brains.”

“Examination of the animals' brains revealed that the mice that ate the high-fat diet (as well as those that received the fat transplants) had weaker synapses between the neurons involved in learning and memory.”

“Chronic inflammation plays key roles in the development of many diseases, including cancer, cardiovascular disease, and diabetes. Inflammation in the brain impairs neurogenesis, the process of forming new neurons. Impaired neurogenesis negatively influences mood and cognitive function.”

“Accordingly, synaptic dopamine concentrations (dopamine that has not bound to a receptor and internalized by the neuron) decreased. Ultimately, this increase in dopamine signaling reduced resting-state activity in the ventral and dorsal striatum and improved functioning of mesocorticolimbic circuits 15 to 45 minutes after insulin exposure.”

“Semaglutide shifted gene activity toward this maintenance work and away from inflammation, changes that overlapped with those associated with calorie restriction. It also reduced signs of protein-folding stress in stem cells that produce blood cells and neurons.”

“From the article: > They knew that chronic activation of the receptor Adora2a [an adenosine receptor] on the endothelial cells that line this important barrier in our brain can let factors from the blood enter the brain and affect the function of our neurons.”

“These regions also exhibited increased glucose metabolism following immunization, indicating better metabolic health in the brain. Finally, immunization increased the number of neurons in the hippocampus, the brain region most associated with learning memory.”

“For example, the loss of smell is one of the most common symptoms reported in SARS-CoV-2 infection, but it is also an early symptom of Parkinson's disease, often preceding diagnosis by many years.”

“Eight weeks later, piglets were transitioned to a solid diet and trained on a challenging memory task that required them to remember which four out of 16 possible locations in a large arena contained hidden food rewards.”
