Neurons managing sugary meals

In Cell Reports: NeuroNexus A2x16-10mm-50-500-177-A32 probes were used for acute, optically-guided recordings in the mouse nucleus accumbens. Two shanks allowed coverage of more of the nucleus at once. Rafael Sandoval-Rodriguez et al. with Luis A. Tellez group at UNAM used latencies of single-unit activity relative to blue light optogenetics stimulation, and responses to drug delivery, to distinguish two NAcc cell types (D1 and D2) that together mediate sugar intake through meals.
