Artificial Neural Network vs. Biological Neural Network: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on February 4, 2024
Artificial neural networks (ANNs) are computing systems inspired by biological neural networks, which are complex networks of neurons in living organisms.

Key Differences

Artificial neural networks (ANNs) are computational models inspired by the human brain's structure, designed to simulate the way biological neural networks process information. ANNs consist of layers of interconnected nodes (or artificial neurons) which process data through weights and activation functions. In contrast, biological neural networks are the actual networks of neurons in living organisms, comprising cells (neurons) that process and transmit information through electrochemical signals.

ANNs are used in machine learning and artificial intelligence to perform tasks like pattern recognition, decision making, and prediction, based on their ability to learn from data. They are capable of adjusting their processing by changing the weights of connections, which is analogous to learning. On the other hand, biological neural networks naturally perform these functions as part of an organism's nervous system, enabling actions, thoughts, and responses to stimuli.

The structure of an ANN typically involves layers of nodes, including input, hidden, and output layers, and is designed by programmers. Its function and efficiency depend on algorithms and computing power. In contrast, a biological neural network is an intricate, naturally occurring structure, evolved over millions of years, and is far more complex than its artificial counterpart. It processes information using a vast network of interconnected neurons, each capable of performing a variety of functions.

ANNs are limited by the current state of technology and understanding of neural processing, and they work within the confines of pre-defined algorithms and computational resources. Whereas, biological neural networks operate on a scale and with a level of complexity that artificial systems have yet to achieve, including the ability to grow, adapt, and repair themselves.

In terms of learning and adaptation, ANNs require training with large datasets to accurately perform tasks and cannot independently acquire new knowledge without retraining. Biological neural networks, however, continuously learn and adapt throughout an organism's life, processing a wide range of sensory inputs and experiences.
