If there are any publicly available datasets then you can find them via GEO and/or SRA/ENA. It looks like the available datasets are ES-cell derived, so if you want sequence from primary microdissected dopaminergic neurons then you're likely out of luck. I should note that this is unsurprising, since it's kind of sketchy to try and get a neuron out of the brain intact without changing its properties.

For the actual analysis, you'll usually download the raw fastq files, so you'll need to trim the files, align them, get counts, and perform statistics yourself. You can use Galaxy to do all of this if you're unfamiliar with using the command line.
