The intricate connection between peripheral metabolism and central nervous system functioning is a topic of growing interest in neuroscience. Phospholipids, a type of lipid crucial for cell membrane structure, play a significant role in synaptic regulation, glutamatergic transmission, and overall cortical excitability within the brain. However, how changes in peripheral metabolism might affect these brain lipid levels and, subsequently, cortical excitability is an area still in need of exploration.

In this episode, we welcome Dr. Vogt, whose groundbreaking research is shedding light on this compelling question. His study discovered that lysophosphatidic acid (LPA) type levels in the blood and cerebrospinal fluid are elevated after overnight fasting, leading to increased cortical excitability. This spike in LPA-related cortical excitability  ...
