What's the difference between Caudate Circuits and the Nigral Stratium pathway? Cuz I thought that Stratium is what stimulates the Substintia Nigra to release Dopamine into the Thalamus...

Still ....no way to overcome or prevent this state....not even able to find the exact cause..is this really do to decrease in neural activity or due to lose in ability of stayatum to sense the dopomine..

These videos were great, but a big problem for me is that there is no explanation as to the origin of tremors. If dopaminergic neurons always aim to inhibit the GPI and by doing so increase the activity of the thalamus -> more movement, then why does damaging these neurons cause tremors? In that case there should be a pathway with dopamine that aims to inhibit unwanted movement. You've said that the indirect pathway aims to decrease unwanted movement, but dopaminergic neurons in this pathway still aims to lessen the effects of this pathway, i.e. increase movement. So I'm still not understanding why a loss of dopamin neurons would cause tremors (unwanted movements).

It's actually because of the side effects of levodopa

kessa cornel Tremors are one of the earliest symptoms of Parkinson's, dyskinesias are side effects, not the same thing
@claudiomaniero645

From what I learnt there are different hypothesis on the exact origin of resting tremors in Parkinson and although they are necessary related to the death of dopamine neurons this process of cell death is not the direct cause of tremors since the direct effect caused by death of dopaminergic neurons is a difficulty in moving. And among the different hypothesis this is the best one I have found www.ncbi.nlm.nih.gov/pmc/articles/PMC3407214/

Dopamine acts as inhibitory neurotransmitter for indirect pathway. This means that nigrostriatal pathway always amplifies movements. I do not think that what you mentioned is right.

My friend was diagnosed with PD(Parkinson’s Disease) in the summer of 2012 and I was diagnosed 5 years ago. Her initial symptoms were quite noticeable so was mine. She first experienced weakness in her right arm and her speech and swallowing abilities were profoundly affected. She did so much to seek help for this disease, as she had been her brother's caregiver a few years earlier for the same disease. Early this year she started on organic/natural PD treatment from Best Dr Madida on RU-vid which she introduced to me too. The treatment worked very effectively and all her symptoms and mine simply disappeared completely after 7 weeks of usage.

So Dopamine turns the direct pathway on, and that excites the cortex. Dopamine turns the indirect pathway down, and that also excites the cortex.
