A new study in mice shows that dopamine neuron activity plays a key role in judgment of time, slowing down the internal clock. Sofia Soares et al investigated midbrain dopamine neurons during timing behavior in mice; when measuring and manipulating mouse activity, the team observed that dopamine neurons controlled temporal judgments on a time scale of seconds.

In the study, whole-brain degree count maps, collected before the start of treatment, were used to identify potential brain regional markers for placebo propensity. Group differences in whole-brain maps for degree count (number of connections of any location to the rest of the brain) between placebo responders and non-responders identified four brain regions that differentiated placebo responders from non-responders. The highest significant difference was seen for the right midfrontal gyrus. Abbreviations: r-MFG - right midfrontal gyrus; ACC - anterior cingulate cortex; PCC - posterior cingulate cortex; r-S2/M1 - right secondary somatosensory and primary motor cortex.
