Do you have a new research idea on cerebral brain asymmetry but are not sure which method you should take? A variety of methods is available for today’s functional brain asymmetry research. After giving a short overview of methods especially used in former times (e.g., lesion studies and microstimulation in patients), this review introduces the method of electroencephalography (EEG) and discusses its advantages. For instance, those include EEG’s high temporal resolution and its relatively low costs of purchase and maintenance.
Furthermore, the review elaborates EEG’s contributions to functional asymmetry research topics such as the processing of emotions, language, and faces. Additionally, by presenting research conducted with alternative methods, we can show that they yield comparable or complementary findings. It becomes clear that while EEG has its merits, a combination of methods is integral in order to thoroughly investigate brain asymmetry. In the end, I suggest a model in order to provide guidance in choosing an appropriate research method (ChARM) for a specific research question.

Chapter Summaries
Introduction: This chapter introduces the concept of brain asymmetry, tracing its origins back to Broca's work. It highlights the limitations of earlier methods like lesion studies and microstimulation, emphasizing their inability to fully account for compensatory brain plasticity and network effects. The chapter positions EEG as a superior method, capable of overcoming these limitations by measuring normal cortical activity, and outlines the paper's goal: to provide a comprehensive overview of EEG in functional brain asymmetry research, highlighting its strengths and weaknesses, and ultimately proposing a method selection model.
Methods of brain asymmetry research: This section differentiates between structural and functional brain asymmetries. It defines functional brain asymmetry as hemispheric differences in stimulus or task processing, setting the stage for the detailed explanation of EEG's capabilities in analyzing these asymmetries. It provides a concise overview of the historical context of the field and sets up the detailed discussion on EEG methodology to follow.
Electroencephalography applied to topics of functional brain asymmetry research: This chapter delves into specific applications of EEG in different areas of functional brain asymmetry research. It explores the use of EEG in understanding emotional processing, language processing (focusing on the N1 component), and face processing (with a focus on the N170 component). The chapter likely demonstrates how EEG's high temporal resolution allows for precise measurement of brain activity related to these cognitive functions, revealing hemispheric differences in processing times or amplitudes of relevant brainwaves.
Limitations of EEG: This chapter acknowledges the shortcomings of EEG, primarily focusing on its limited spatial resolution and the challenge of establishing causation. It contrasts EEG's strengths (high temporal resolution) with its weaknesses (low spatial resolution), emphasizing the difficulty in pinpointing the exact location of neural activity. The chapter concludes by introducing the ChARM model, a proposed framework for selecting the most appropriate research method based on the specific research question.
