      Systems biology approaches allow the examination of brain processes at both molecular and systemic levels.

      Deep diving into systems biology reveals that the reactions occurring in neural pathways can be described by complex systems of equations. For instance, consider metabolic pathways in neurons where enzymes convert substrates into products. These reactions can be described using Michaelis-Menten kinetics, a fundamental model in enzyme kinetics. The basic Michaelis-Menten equation is: \( v = \frac{V_{max}[S]}{K_m + [S]} \)where \( v \) is the rate of reaction, \( V_{max} \) is the maximum rate, \( [S] \) is the substrate concentration, and \( K_m \) is the Michaelis constant. Such equations help model the efficiency and regulation of enzymatic reactions in neural pathways, offering insights into metabolic and signaling networks in the brain. Advanced software tools also enable simulating entire neural networks, providing a multidimensional view of cellular processes and facilitating a deeper understanding of neuroproteomics at systemic levels.
