Über diese Lernkartei

This flashcard set introduces primary school students to the fundamentals of the nervous system and brain function. It covers key topics like neurons, neurotransmitters, sensory processing, and brain anatomy, including the cortex, hippocampus, and different lobes. The flashcards explain how the brain controls movement, perception, and bodily functions, as well as the roles of various neurotransmitters in mood, memory, and muscle action. This set is ideal for young learners seeking to understand the basics of how the brain and nervous system work, providing a solid foundation for further study in psychology and neuroscience.
