Explore the impact of digital technologies on the brain, behavior, and emotional well-being through the lenses of neuroscience, psychology, and cognitive science. We will examine how modern devices and artificial intelligence influence cognitive functions such as attention, memory, learning, and decision-making, as well as social interaction and mood. We will also address ethical concerns, including privacy and technology-based addictions, and discuss the effects of digital media on mental health. The course highlights how advances in neuroscience and clinical practice offer new tools for improving mental well-being in a tech-driven world. Through research-based insights and practical strategies, we will gain a deeper understanding of how the brain adapts to digital life: and how to navigate it effectively.
