Definition and functioning of RNNs

The functioning of spiking recurrent neural networks (SRNNs) can be outlined by considering the individual components and their interactions. At a basic level, an SRNN consists of a set of recurrently connected spiking neurons that process information over time. The neurons in an SRNN are organized into layers, where each layer contains a group of neurons that have similar functions or characteristics. Information is transmitted through the network via spike events, which are discrete voltage changes that represent the occurrence of an action potential in a neuron. Additionally, an SRNN can have feedback connections, allowing signals to be transmitted from higher layers back to lower layers.
