Other functions of the lobe include signals from memory, voice, vision; a sense of touch, pain; visual and spatial perception.
Reaction rates generally increase with increasing reactant concentration, increasing temperature, and the addition of a catalyst. Physical properties such as high solubility also increase reaction rates.
