Bursting EPSCs are increased by song exposure. a Generation of bursting behavior of glutamatergic neurotransmission after bicuculline application to NCM slices. Left trace no drug, right trace after bicuculline application. b Percentage of neurons that presented bursting neurotransmission after bicuculline (Ccontrol, S song-exposed, *p < 0.05); values in parentheses indicate absolute numbers of recorded cells with bursting behavior and total number of recorded cells per group. c Example of an individual spontaneous bursting EPSC observed in an NCM neuron from a song-exposed male without blocking GABAergic transmission. The currents were measured at −20 mV using a low-chloride internal solution. Under these conditions, glutamatergic currents are downward and GABAergic currents upward
