How does the brain encode information? What is the basis for learning and memory? In this section, Dr. Gareth Evans will explore these questions at the level of the synapse.

Here are some questions to consider while you’re watching the video. We’d be happy to hear from you in the comments once you’ve watched the video.

• Are the changes made to synapses during learning permanent? Or will they return to the state before learning if not used much?
• Will synaptic plasticity keep increasing the activity of synapses (how loud can a synapse shout?)
• Does sleep have a role in learning and memory?
