Electrode array with integrated optical fiberThis recording device contains 32 tungsten microwire electrodes and one optical fiber. The device can be used to record from multiple sites in the brain, as well as optically stimulate the neurons around these sites.Enlarge
AgRP neurons of the arcuate nucleusThis image depicts AgRP (agouti-related peptide) neurons (magenta), critical drivers of hunger that sit at the base of the hypothalamus in the arcuate nucleus. Given their anatomical position in the brain, they are in an ideal position to integrate signals from both brain and peripheral organs. These neurons are both sufficient and necessary for mediating food intake.Enlarge
