Newswise — An international research team investigates the relationship between nerve (neuron) activity in the whiskers of mice and executing a simple task. The study is published ahead of print in the journal Function.

The research team used two-photon imaging to directly compare the activity of two different neuron groups during a reward-based activity in which mice licked a water spout in response to whisker stimulation or an auditory tone.

The study’s results support the hypothesis that “signaling from [the primary whisker somatosensory barrel cortex] to the [secondary whisker somatosensory barrel cortex] might be important for whisker detection,” the authors wrote. Additional studies may help determine whether the properties of the involved neurons change.
