Memories in the conventional sense are stored in the brain.

By stretching the definition of memory, you can get to the conclusion that the whole body remembers. Scientists have found that the neurons in the spine learn when practicing motor tasks. The immune system remembers pathogens. Hormonal glands remember concentrations of relevant hormones by growing / shrinking. Muscles (including the heart) remember exercise by growing. If you play the guitar your fingertips harden, they "remember" the stress and toughen up in anticipation. And every single cell will learn by epigenetic changes. Maybe you could say that diabetes type 2 happens because the cells learn to respond less to insulin.
