Exploring the Wonders of the Brain using Computer Simulation

Simulations bring together findings from molecular biology, electrophysiology, and anatomy into unified models. This makes it possible to study how processes at one level (e.g., ion channel kinetics) influence higher-order brain functions (e.g., sensory perception, motor control).

Some brain processes cannot be easily measured in vivo, especially in humans. Computational models let us “experiment in silico” by selectively manipulating variables (e.g., removing a synaptic input, modifying ion channel properties) to predict outcomes.

By simulating disease states, researchers can compare them with healthy conditions, helping to uncover causal mechanisms and suggest therapeutic interventions.

Simulations can reveal how networks evolve over time, how pathological conditions (like Parkinson’s disease) alter circuit function, and how neuromodulators change activity patterns. They provide mechanistic insight beyond static experimental observations.

Modeling generates testable predictions, reducing the need for trial-and-error experiments. This synergy accelerates discovery and optimizes the use of experimental resources.

Biophysically detailed brain simulations also inspire new algorithms for artificial intelligence, robotics, and neuromorphic computing by replicating biological principles of computation and learning.
