Artificial Neural Networks are computational models inspired by the human brain, used for tasks like pattern recognition, while Biological Neural Networks consist of real neurons in living organisms, processing sensory, motor, & cognitive information.
Artificial Neural Network vs. Biological Neural Network

Key Differences

Artificial Neural Networks (ANNs) are computer-based systems that mimic the way biological neural networks work. They are composed of interconnected units (nodes) that process information using a connectionist approach to computation. Biological Neural Networks, on the other hand, are made up of actual biological neurons, connected through synapses, and are responsible for processing and transmitting information in living organisms.

ANNs learn from data and adjust their processing by changing the weights of connections between nodes, using algorithms like backpropagation. This learning is based on data patterns and is often used for tasks like image and speech recognition. Biological Neural Networks learn through a process known as synaptic plasticity, where the strengths of synaptic connections are adjusted based on experience and neural activity, crucial for memory and learning.

In ANNs, the structure and functionality are simplified abstractions of biological networks, designed for efficiency in specific tasks. They do not replicate the full complexity of biological neural networks, which consist of a vast array of different types of neurons, each with unique properties, and are capable of more complex, holistic processing.

The speed of processing in ANNs is dependent on computational power and can be incredibly fast, but lacks the adaptability and parallel processing capabilities of biological neural networks. Biological networks, while slower in signal transmission, can perform complex, parallel processing, making them more efficient for certain types of information processing.

ANNs are primarily used in machine learning and artificial intelligence for solving complex problems in various fields, from medicine to finance. Biological Neural Networks, however, are integral to the functioning of living organisms, enabling responses to environmental stimuli, conscious thought, and bodily functions.
