The brain response to coffee consumption: Electroencephalogram (EEG) changes and implications

Coffee consumption has become a daily ritual for a significant portion of the global population, primarily due to its ability to alleviate tiredness, enhance alertness, and improve concentration. The effects of coffee on the human body, particularly the nervous system, have been a longstanding inquiry within the field of neuroscience. This chapter aims to provide a comprehensive overview of the scientific community’s efforts in understanding the positive and negative effects of coffee consumption on the central nervous system, with a focus on quantifiable changes observed in electroencephalography recordings. By examining the electrical behavior of brain signals, this research sheds light on the neurophysiological impact of caffeine, uncovering valuable insights into its influence on brain activity. These findings contribute to a deeper understanding of the intricate relationship between coffee consumption and the central nervous system, paving the way for future investigations and potential therapeutic applications.
