Molecular neuroscience delves into the molecular and cellular mechanisms that govern the function of the nervous system. By studying neurotransmission, signal transduction, and neuronal development at the molecular level, researchers aim to uncover the processes underlying neurological diseases such as Alzheimer's, Parkinson's, and epilepsy. Advances in molecular techniques, including CRISPR gene editing and single-cell RNA sequencing, are enabling a more detailed understanding of how molecular changes affect brain function and behavior. This field also explores the role of proteins, lipids, and small molecules in neuronal communication, synaptic plasticity, and neuroinflammation. As these insights translate into new therapeutic targets, molecular neuroscience holds the key to developing more effective treatments for a variety of neurological disorders.
