Molecular neuroscience helps to understand complex mechanisms responsible for regulating the nervous system at the molecular level, highlighting the fundamental building blocks of neurology. It helps to navigate the understanding of how molecules like receptors, neurotransmitters and ion channel execute neural function helping to understand progression of neurological disorders.
Neurodegeneration is a process in which neurons get damaged or becomes nonfunctional and can be responsible for many neurological disorders. Mostly this is caused by old age related underlying neural issues. Alzheimer's and Parkinson's are some of the neurological diseases that are responsible for neurodegeneration. Abnormal protein aggregation, mitochondrial dysfunction and oxidative stress are some of the plausible reasons responsible for neuronal demise.
