Newborn neurons in the hypothalamic area Representative BrdU (red) and NeuN (green) double-labeled sections of the hypothalamus inspected by laser-scanning confocal microscopy. HE43 and CN43 show samples on the 43rd day of heat exposure and of control, respectively. Yellow dots (shown as arrows) indicate BrdU and NeuN double-positive cells and therefore newborn neurons. 3V, third ventricle; scale bar, 100 µm. The photo samples are prepared using our previous data already published in a paper.²⁶
