The central nervous system, or CNS, is made of the brain and spinal cord. The brain receives sensory information, processes it, and coordinates responses such as movement, memory, emotion, and homeostasis.

Step-by-step lessons covering Edexcel A A Level Biology Brain structure and imaging for A Level Biology. Each lesson works through exam-style questions in Paper 1, Paper 2 and Paper 3 format. Build a strong foundation in cell biology and biochemistry early on, since later topics on genetics, ecology and physiology all draw on these core concepts.
