<Original Article> Time Course of Cerebellar Flocculus Visual Complex Spike Responses

It is well known that the flocculus complex spike (CS) is driven by retinal slip. We studied the time course of visual CS responses in the anesthetized and paralyzed cat. Onset of contralaterally-directed constant-velocity visual-pattern rotation evoked an initial increase in the CS rate, which gradually decreased but continued to remain above the spontaneous activity level during rotation periods as long as 50s (onset response). Then, cessation of the rotation caused a decrease in the CS rate, which gradually returned to the spontaneous rate (cessation response). Ipsiversive rotation caused a similar CS time course with an inverse response-polarity. The duration of the cessation response increased with increases in the stimulus duration. Acceleration and deceleration of retinal slip velocity did not affect the time course of the responses. Thus, the flocculus CS is modulated time-dependently during the onset and cessation phases of retinal slip regardless of retinal-slip stimulus parameters such as velocity and acceleration. It is concluded that the flocculus CS encodes time information of the retinal-slip onset and cessation but does not encode precise quantitative information of the retinal-slip velocity and acceleration.journal articl

Thermoelectric properties of Al_{82.6−x}Re_{17.4}Si_x (7≼x≼12) 1/1-cubic approximants

The thermoelectric power S(T) and thermal conductivity _k(T) were systematically studied for a series of Al_{82.6−x}Re_{17.4}Si_x(7≼x≼12) 1/1-cubic approximants. We found that S(T) of these approximants is characterized by large magnitude, sign reversal with varying composition, and nonlinear temperature dependence, all of which are also known as characteristics of the corresponding quasicrystals. The calculated S(T) on the basis of the Boltzmann transport formula with accurately determined electronic structure showed extremely good agreement with the measured ones not only in their magnitude but also in the temperature and composition dependence. These results strongly indicate that these characteristic behaviors in S(T) of the approximants and the corresponding quasicrystals are brought about by their characteristic electronic structure, i.e., the presence of a pseudogap across the Fermi level.journal articl
