While working at Toronto's Hospital for Sick Children, as a child neurologist and research neuroscientist, I created series of art works about thought, on paper. These pieces were made by applying acrylic paint, or black transfer lettering to archival-quality, water-color paper. Several pieces were done by applying transfer lettering to accounting ledger paper. The series were either smaller in size (most of the pieces approximately 12 x 15 inches in size), or larger (14 x 20 inches in size). All of these works were completed in 1987 and 1988.
