Optogenetics uses light-sensitive proteins to make selected cells responsive to light, allowing researchers to control their activity and investigate how specific neurons and neural circuits contribute to brain function and behaviour. Pixabay

It is fascinating to consider how this intricately folded organ, tucked away inside our heads, can give rise to a memory, shape an emotion, influence a decision or direct the body's movements. Inside it, billions of nerve cells communicate through a complex network of connections. Their activity underlies our ability to think, remember, perceive the world and experience emotions.…
