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 sensorimotor information into the deep nuclei, which in turn pass it on to various premotor areas, thus regulating the gain and timing of motor actions. Mossy and climbing fibers also feed this information into the cerebellar cortex, which performs various computations, resulting in the regulation of Purkinje cell firing. Purkinje neurons feed back into the deep nuclei via a potent inhibitory synapse. This synapse regulates the extent to which mossy and climbing fibers activate the deep nuclei, and thus control the ultimate effect of the cerebellum on motor function. The synaptic strength of almost every synapse in the cerebellar cortex
