Visual pathway showing both eyes, partial crossing at the optic chiasma, and left visual field information reaching the right primary visual cortex Visual information starts in the retina, where photoreceptors convert light into nerve impulses. Signals leave each eye through the optic nerve and head toward the brain.

Step-by-step lessons covering Edexcel A A Level Biology Visual development, animal studies and habituation 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.
