Gene enrichment at the positive pole of the dog fourth eigenvector. The up-regulated genes are integrated into molecular pathways centering around long-term memory that can explain, to a great extent, the phenotypical behaviors of dogs. According to their biological relevance, the enriched gene subsets are grouped from top to bottom by long-term memory, neurotransmission, synaptic plasticity, LTP induction, and other LTP mechanisms, shown in different colors.
