Microglia in the brain nibble on synapse to induce remodeling of neural circuits. Kevin mentions his new online seminar on five ways to enhance long-term learning. A&P is the story of the human body, so A&P professors act as storytellers. Kevin gives some practical tips on how to do that effectively.

(0:47) New information shows that microglia nibble on presynaptic neurons using trogocytosis, rather than phagocytosis, to prune synapses during memory formation to help remodel brain networks. Microglia also induce postsynaptic spines to "reach out" to form new synapses with presynaptic neurons.
(6:50) Kevin has a new online seminar on five strategies to enhance long-term learning in A&P courses.
(8:05) Kevin explains why he thinks storytelling is the heart of effective teaching, especially in the A&P course. He outlines the "storytelling persona"; making sure there is a beginning, middle, and end to our stories, applying storytelling to both lectures and the entire course, using drama, conflict and resolution, and other techniques.
