With the development of the times, the continuous deepening of new curriculum reform, and gradual popularity of English teaching, disparities in the regional economy and education spread in China, and thus there appear various problems in the teaching process, especially English vocabulary teaching. Word, as the basic unit of language, is one of the three major elements of language, which plays a major role in the realization of the communicative function of language. Most students use the way of memorizing English words by their root but have no effective way to remember English words. This paper discusses the relationship between cognitive neuroscience and English vocabulary memory, and studies the information source entropy characteristics of EEG signals under different states of vocabulary memorization. This method provides a new idea and tool for the determination of the relationship between cognitive neuroscience and the effectiveness of English vocabulary teaching, and seeks more ways, more organizational forms and methodological strategies so as to help students better memorize vocabulary so that it has broad prospects for development in English teaching
