The neural machinery underlying our olfactory sense continues to be an enigma for neuroscience. A recent review in Neuron seeks to expand traditional ideas about how neurons in the olfactory bulb might encode information ...
Looking for answers about how the brain works amid age-related hearing loss, Johns Hopkins Medicine researchers say they have found that old mice were less capable than young mice of "turning off" certain actively firing ...
