These are the same neurons that are usually activated in anticipation of movement. What is special about this, is that as the birds learned new songs or pieces of new songs, activation of these neurons declined. This effect was due to inhibitory interneurons whose firing frequency increased as the birds practiced and improved their accuracy. Activation of these inhibitory interneurons prevented any further changes to the circuitry once…

The book delves into the turn-of-the-century practice of photographing medical students with cadavers - photos that today read as weird, grotesque, even offensive.
The photos unearthed by Warner and Edmonson depict an astonishing variety of…
