生物神经网络（Biological Neural Networks）一般指生物的大脑神经元、细胞、触点等组成的网络，用于产生生物的意识，帮助生物进行思考和行动。

• 1872年，意大利的医学院毕业生高基，在一次意外中，将脑块掉落在硝酸银溶液中。数周后，他以显微镜观察此脑块，成就了神经科学史上重大里程碑 --“首次以肉眼看到神经细胞”。

In neuroscience, a biological neural network (sometimes called a neural pathway) is a series of interconnected neurons whose activation defines a recognizable linear pathway. The interface through which neurons interact with their neighbors usually consists of several axon terminals connected via synapses to dendrites on other neurons. If the sum of the input signals into one neuron surpasses a certain threshold, the neuron sends an action potential (AP) at the axon hillock and transmits this electrical signal along the axon.
