We will develop electronic building blocks to investigate biological signal processing. In particular, we will investigate the auditory pathway and develop the most accurate electronic model of the biological cochlea and auditory nerve. These will be followed by electronic circuits that model the processing of sensory signals in the brain. Processing signals with neural spikes offers distinct advantages over current analogue and digital signal processing techniques in terms of noise, energy consumption and extraction of temporal information. We will implement the first spike-based models of pitch and timbre perception, and a neural model of speech recognition in noisy environments.

我们将开发电子积木来研究生物信号处理。特别是，我们将研究听觉通路，并开发生物耳蜗和听觉神经的最准确的电子模型。随后是模拟大脑中感觉信号处理的电子电路。与当前的模拟和数字信号处理技术相比，在噪声、能量消耗和时间信息提取方面，用神经尖峰处理信号具有明显的优势。我们将实现第一个基于尖峰的音高和音色感知模型，以及噪声环境中语音识别的神经模型。
