You might think brain surgery is all cool precision and high-stakes drama. Sometimes it is. But more often, it's a gritty, smelly, surprisingly absurd job—one that involves titanium screws, tumors the size of grapefruits, and moments so human they'll break your heart or make you snort with laughter behind your surgical mask.

In Off the Top of My Head, Dr. Barbara Lazio peels back the sterile curtain of the operating room and shares the unexpected stories that come with a life spent elbows-deep in the human brain. With warmth, wit, and a scalpel-sharp eye for detail, Dr. Lazio invites readers into her world—where mortality is never far away, but neither is meaning, connection, or the occasional gallows-humored joke.
