  "account": "The development of AVOCODO, an open-source MATLAB-based software platform, has revolutionized the way behavioral annotation is integrated into developmental EEG research. By seamlessly connecting synchronized video recordings with EEG data, AVOCODO streamlines the identification of behavior-related artifacts and the exploration of brain-behavior relationships.\n\nWhat sets AVOCODO apart is its ability to read native EGI MFF recordings and synchronize embedded video with EEG, providing a unified platform for both EEG preprocessing and behavioral annotation. The software automatically visualizes the audio spectrogram, making it easier to precisely annotate vocalizations and ensure accurate coding.\n\nOne of the key advantages of AVOCODO is its flexibility in supporting fully customizable behavioral coding schemes. Researchers can tailor the annotation process to their specific needs, allowing for more accurate and meaningful data collection. Additionally, the software offers the option for EEG visualization during the annotation process, enabling researchers to perform quality control checks and ensure the integrity of the data.\n\nAVOCODO also streamlines the annotation workflow by enabling researchers to reload previously annotated recordings for review and inter-rater verification. This feature promotes consistency and reliability in the annotation process, ultimately leading to more robust research findings. Furthermore, AVOCODO allows for the direct export of annotations as CSV files, facilitating seamless integration with other data analysis tools.\n\nSince its inception in 2024, AVOCODO has already made a significant impact in the field. It has been utilized internally across five developmental EEG studies involving approximately 500 pediatric participants and over 3,000 EEG recordings. By bridging the gap between behavioral annotation and EEG preprocessing within a single open-source workflow, AVOCODO has the potential to greatly enhance the efficiency, reproducibility, and scalability of behavioral annotation in developmental EEG research.",
  "summary": "Behavioral annotation of synchronized video recordings is an essential step in developmental electroencephalography (EEG) research, supporting both the identification of behavior-related artifacts and the investigation of brain-behavior relationships. Existing annotation workflows, however, are often fragmented: proprietary EEG software provides limited flexibility for behavioral coding, whereas…",
