Document Summary

Mineral acids also affecti the detection of acidness. Suppose i measure how much time you spend smelling an odorant. Adaptation: not really sure whether the things i think are actually different to the brain (if it"s the same to the brain, the brain will adapt) Pick a feature of the odourant and vary an element of it and present it to the subject. If there is no adaptation, then you have a new dimension. No direct link between chemical composition and odour. You have no idea where the odour is. Pattern tells us what were smelling is not molecular structure or a rose or vanilla for example. You increase activity in the relevant glomeruli, you increase activity in other unrelated glomeruli, You change the pattern of activity over the entire olfactory bulb. When you shine a different molecule, you would get a different pattern. But if you stay with the same molecule, but incease the concentration.
