The part of the horse's brain that controls memory is the limbic system. It is located in the middle of the brain, and is responsible for emotions, instincts, and memories. This is where you find the amygdala, hippocampus, hypothalamus, and thalamus. In order to learn something, information must be transferred from the senses to the brain, and then to the part of the brain that controls memory. In horses, this is the limbic system. The information from the senses goes to the sensory cortex, which is just behind the eyes. From there, the information is sent to the hippocampus. The hippocampus is a very important part of the brain because it is where memories are stored.
