Population spikes often reflect synaptically induced firing and therefore, they can be classified as a type of field excitatory postsynaptic potentials. In some areas of the brain, such as the hippocampus, neurons are arranged in such a way that they all receive synaptic inputs in the same area. Because these neurons are in the same orientation, the extracellular signals from the generation of action potentials don't cancel out, but rather add up to give a signal that can easily be recorded with a field electrode. The PS is usually recorded with an extracellular electrode placed close to neural cell bodies or axons. The first interpretations of hippocampal field potentials were developed by Per Andersen. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Population spike」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
