• Neostriatum medium spiny direct pathway GABA cell Show Other

• Soma Show Other

• I L high threshold Show Other

• Whole-cell voltage-clamp recordings showed that HVA currents were present in at least 95% of neostriatal neurons, but that the majority of them appeared to belong neither to the "L-type" nor the "N-type" classification Show Other
• However, recordings in slices showed that D1 receptor activation can either inhibit or enhance evoked activity, depending on the level of membrane depolarization, by modulating an L-type Ca2+ conductance Show Other
