Rhythmic oscillations of neural excitability underlie coordination of network processing, and have been reported in these dopaminergic nuclei at several frequency bands. This paper provides a comparative characterization of several frequencies of oscillations of local field potential and single unit activity, highlighting some behavioral correlates.<h4>Methods</h4>We recorded from optogenetically identified dopaminergic sites in four mice training in operant olfactory and visual discrimination tasks.<h4>Results</h4>Rayleigh and Pairwise Phase Consistency (PPC) analFrontiers in cellular neuroscience1131313https://www.ebi.ac.uk/biostudies/studies/S-EPMC10326437biostudies-literatureRhythmic oscillations in the midbrain dopaminergic nuclei in mice.PMC10326437Pompili MNNishijo HWiener SITodorova RMatsumoto JPapaleo FVandecasteele MOberto VJVenance LfalseRhythmic oscillations in the midbrain dopaminergic nuclei in mice.<h4>Introduction</h4>Dopamine release in the forebrain by midbrain ventral tegmental nucleus (VTA) and substantia nigra pars compacta (SNc) neurons is implicated in reward processing, goal-directed learning, and decision-making.
