There’s currently no way to selectively enhance dopamine in specific brain pathways; any increase affects multiple circuits simultaneously. While substances like L-Tyrosine can boost dopamine levels, they do so across all pathways, which can lead to side effects, especially in individuals taking antipsychotic medications. This nonselective nature of dopamine modulation highlights the complexities of treating conditions like schizophrenia and Parkinson's disease, where movement and cognitive functions are intricately linked to dopamine levels.
