Spiking Neural Networks
Artificial neural networks that communicate through discrete timed signals (spikes) rather than continuous values, more faithfully mimicking the functioning of the biological brain. These architectures enable more energy-efficient information processing.
Memristor
Non-linear passive electronic component whose resistance depends on the history of the current that has passed through it, simulating the behavior of a biological synapse. Memristors are fundamental for materially implementing synaptic plasticity in neuromorphic architectures.
Synaptic Plasticity
Mechanism by which the strength of synaptic connections between neurons can be modified based on activity, forming the basis of learning and memory. In neuromorphic computing, it is implemented materialistically to enable autonomous adaptation of circuits.
Neuromorphic Chip
Integrated circuit specially designed to implement neuromorphic computing architectures with physical neurons and synapses. These chips optimize parallel processing and low energy consumption typical of biological systems.
