The goal of this observational study is to learn about the usability of portable EEG sensors (REMI) in the home with infants and young children. The main question it aims to answer is: Can families comfortably use portable EEG sensors (REMI) in the home with their children? Families will wear the REMI sensors for an extended period of time (30 minutes to 1 week) and answer online survey questions.

There has been significant innovation in remote testing procedures over the past few years, accelerated in part as a result of the COVID-19 pandemic-related testing restrictions. Shifts to remote testing have included standardization of methods for survey administration and adaptations of traditional in-lab paradigms for use in remote assessments. The current project will develop and standardize a remote protocol measuring infant brain function using wireless, portable, user-friendly, single-channel EEG sensors. Infant cortical activity will be collected using the REMI (Remote EEG Monitoring System), a wireless, single-channel sensor. The sensors are applied to the head using specially designed infant-friendly adhesive stickers (to avoid skin irritation). Families of children between the ages of 1 month and 24 months will be eligible to participate in this study. Experimenters will initiate the sensors and will instruct families on how to use the REMI system independently (i.e., changing adhesive stickers when necessary). Families will then record child EEG for an extended period of time (30 minutes to 2 weeks). When recording is complete, the family will mail back all equipment to the lab.

Inclusion Criteria:

• Child is between the ages of 1 month and 24 months of age

Exclusion Criteria:

• Child has known neurodevelopment disorder
• Legal guardian is under 18 years of age

Families with children 1-month to 24-months of age will be enrolled in this study.
