Neuroscientist Nazareth Castellanos reveals how sleep and emotions shape learning success

A recent event in Madrid brought together students, educators, and thought leaders to explore the science behind thoughts, feelings, and actions. Neuroscientist Nazareth Castellanos led the discussion, offering insights into how attention, emotional balance, and physical wellbeing shape learning and decision-making. The event, organised by Forbes in partnership with ISP Iberia Schools, featured Castellanos as the keynote speaker. She challenged the traditional idea of a linear career path, urging attendees to embrace flexibility in their professional journeys.

Two students from Lady Elizabeth School, Lola S. and Yuexin, took part in the conversation. Lola raised a question about the role of sleep in learning, prompting a detailed response. Castellanos explained that sleep helps clear waste from the brain and strengthens memory in the hippocampus—making it especially important before exams. Throughout the session, Castellanos emphasised the need for emotional balance and physical health. These factors, she argued, are essential for effective learning and making conscious choices.

The discussion provided practical takeaways for students and educators alike. Castellanos’ explanations on sleep, memory, and wellbeing highlighted how small habits can impact academic and professional success. The event reinforced the value of science-backed strategies in education.
