supper butter cake

The cakes smell good. This is the third day I am taking porridge for special reason. How wonderful is to have a good smelling function.

A cellular "porthole" known best for its role in the digestive system apparently has a major role in helping the brain sense odors, Johns Hopkins scientists report in the Feb. 17 issue of Neuron. The porthole, which lets chloride into cells, is also critical in digestion, hearing, balance, and fertility. The researchers suggest that digestive system cells and odor-detecting cells use the same chloride porthole, or ion transporter -- the former to facilitate secretion of digestive juices, and the latter to communicate information about scents to the brain.
Odor-detecting nerve cells are long and thin, extending from the tissues lining the nose where odors are sensed all the way to the brain. When you smell cookies baking, odor molecules bind to these cells, triggering a series of molecular "gates" on the cell surface to open. The open gates let charged ions, including chloride, move in and out of the cell, creating differences in charge between the inside and outside of the cell. Such differences allow electrical signals to travel to the brain, telling you that home-made cookies are nearby.
