I haven't read this book, but in correspondence with Gross some years ago
he indicated that he'd never discovered any more such cells. Maybe things
have changed since then, but I think the evidence for grandmother cells is
quite weak. The evidence seems to indicate that recognition is spread over
an ensemble of cells and that any given cell can contribute to the
recognition of many objects/states.
