The pathophysiology and anatomical basis of most tremors remains poorly understood. One particular theory of essential tremor, the olivary hypothesis, has gained support from various studies. These studies point to the olivary nucleus as possible central rhythm generator. Cells in the olivary nucleus show spontaneous rhythmic discharges that can be suppressed by alcohol. Since alcohol is known to suppress tremor in some patients with essential tremor, one can theorize that it is through its effect on the olivary nucleus; that is, the inferior olive is the generator of the tremor. Given this assumption, we intend to study the effect of alcohol on three different kinds of tremor: the 8-12 Hz component of physiological tremor, symptomatic palatal tremor and essential palatal tremor. Our hypothesis is that the central generator of each of these types of tremor lies in the inferior olive and that the ingestion of alcohol should reduce the amplitude of the tremor, similar to the effect of alcohol seen in essential tremor.
