Free fatty acid receptor 1 high abundance. FFA1 receptors are present over the entire brain, but in highest numbers in the medulla oblongata and the substantia nigra. Recent studies have also observed that FFA1 was present in the olfactory bulb, striatum, hippocampus, midbrain, hypothalamus, cerebellum, cerebral cortex and in the spinal cord. Fatty acids play an important role in normal brain development as well as maintaining proper neuronal function. It has been found that certain fatty acids that are in abundance in the brain may be linked with FFA1. These fatty acids likely activate FFA1, inducing an intracellular response. It has been found that docosahexaenoic
Anatomy of the cerebellum posterior inferior portion of the cerebellum, the inferior cerebellar peduncle, the nucleus ambiguus, the vagus motor nucleus, the spinal trigeminal nucleus, the solitary nucleus, and the vestibulocochlear nuclei. There is considerable variation in the size and shape of the cerebellum in different vertebrate species. It is generally largest in cartilaginous and bony fish, birds, and mammals, but somewhat smaller in reptiles. The large paired and convoluted lobes found in humans are typical of mammals, but the cerebellum is generally a single median lobe in other groups, and is either smooth or only slightly grooved. In mammals, the neocerebellum is the
