WebJul 20, 2024 · The PVH is composed of three main types of neurons, magnocellular, parvocellular, and long-projecting neurons, which play imperative roles in the regulation of energy balance and various endocrinological activities. WebParvocellular cells, also called P-cells, are neurons located within the parvocellular layers of the lateral geniculate nucleus (LGN) of the thalamus. " Parvus " means "small" in Latin, and the name "parvocellular" refers to the small size of the cell compared to the larger magnocellular cells.
