Olfactory bulb evidence of behavioral learning

Results published in Cell Reports describe a neural representation of learning that mediates the Bruce Effect in mice. Michal Yoles-Frenkel et al. with Yoram Ben-Shaul’s group at the Hebrew University, Jerusalem used NeuroNexus 32-channel probes (A4x8-5mm-100-200-177-A32 or A4x8-5 mm-50-200-177-A32) to record mitral tufted cells in the accessory olfactory bulb of adult, female mice, confirmed using DiI. They found olfactory responses differed across time scales of chemosignal presentation.
