The term ASIA element (an acronym for analog signal memory with intrinsic adjustment) denotes a motif for biological information processing structures that is based on leaky integration of an input signal.
Thus, an ASIA element performs the following tasks:
- Retaining the information with given time constants.
- Automatic extinction of obsolete signals.
- Linear dependence of the system`s response from input signals to prevent distortion effects.
