    Other evidence in support of the dopamine hypothesis relating to the substantia nigra include structural changes in the pars compacta. Some of the other changes in the substantia nigra include increased expression of NMDA receptors, and reduced dysbindin expression. Increased NMDA receptors may point to the involvement of glutamate-dopamine interactions in schizophrenia. Due to the changes to the substantia nigra in the schizophrenic brain, it may eventually be possible to use specific imaging techniques to detect physiological signs of schizophrenia in the substantia nigra. https://www.youtube.com/watch?v=nEnklxGAmak Another factor that contributes to dopamine accumulation is an enzyme called MB-COMT, Membrane-bound Catechol-O-methyltransferase.…

    Anti-Calbindin binds to Calbindin (CB) and labels GABAergic neurons In our immunohistochemistry (IHC) experiment, we used anti-Calbindin as our primary antibody, Goat anti-Rabbit 488 IgG as our secondary antibody (“488” meaning that the fluorescent dye is excited at a wavelength of 488nm, fluorescing green), and DAPI-mounting serum as a DNA (nucleus) marker with blue fluorescence for reference against anti-Calbindin-marked GABAergic neurons (Lammel, 2016). While GABAergic-neuron-expressing…

    In the human body, motor commands are created in a division of the prefrontal cortex (responsible for higher level cognition) known as the neocortex. The neocortex houses the motor cortex and thus is responsible for motor control, which is the primary impairment in Parkinson’s Disease (Kaas & Stepniewska, 2016 SD). Onset typically follows a significant drop in the presence of the neurotransmitter dopamine, which in this case is generated from a part of the brain called the substantia nigra. The…

    movement. Parkinson’s disease is often known as PD and it is a progressive neurological condition, which means the sickness and symptoms get more severe as time goes on (Noble, 2007).

    disease, which according to Dr. Bautista and Dr. Grossman is a progressive movement disorder related to the basal-ganglia of the brain, which control movement of the body. At the end of the substantia nigra of the basal ganglia lies the pathway to muscle cells that use dopamine as the neurotransmitter (Bautista & Grossman, 2014). This nigrostriatal pathway is disrupted in Parkinson’s disease, and 70-80% of the neurons need to be lost before clinical symptoms of Parkinson’s develop (Lehne, 2013).…
