All senses and hormone-producing glands send signals to the brains, where they interpret the signals, before the body is controlled by the nervous system. The brains also send signals to the most important hormone-producer; the pituitary gland. Brain activity needs a big dose of energy, and even though the brains are less than one percent bodyweight, it receives twenty percent of the blood that is being pumped through the heart.
The cat brain exists out of billions of special cells; neurons. Every cell has to 10.000 connections with other cells. If a cat is seven weeks old, the messaged travel through the brains with a speed of 390 km per hour. This speed drops when the cat gets older.
The brains of a cat look like of that from a small mammal, anatomy-wise. The cerebellum coördinate and streamline the movements from the muscles. The cerebrum control the learning, emotion and behavior. The brain stem forms the connection with the nervous system. The network of cells is called the “limbic system”, integrate the instinct and learning ability.
The hormones that are produced in the brain regulate the most functions, like the speed of the metabolism and the creation of cortisol in the adrenal glands in response to danger. The production of the sex hormones and all that has to do with that, are regulated by the follicle stimulated hormone (FSH) with female cats, and is regulated by the Luteinizing hormone (LH) with male cats.
