The low-temperature phy.ical vapor deposition process of atomically.thin two-dimensional transition metal dichalcog.nide(2D TMD) has been g.ining.attention owing.to the cost-effective production of diverse electrochemical cataly.ts for hy.rog.n evolution reaction(HER) applications. We, herein, propose a simple route toward the cost-effective phy.ical vapor deposition process of 2D WSe2 lay.red nanofilms as HER electrochemical cataly.ts using.RF mag.etron sputtering.at room temperature(y.controlling.the variable sputtering.parameters, such as RF power and deposition time, the loading.amount and electrochemical surface area(ECSA) of WSe2 films deposited on carbon paper can be carefully.determined. The surface of the sputtered WSe2 films are partially.oxidized, which may.cause spherical-shaped particles. Reg.rdless of the loading.amount of WSe2, Tafel slopes of WSe2 electrodes in the HER test are narrowly.distributed to be ~120–138 mV dec-1, which indicates the excellent reproducibility.of intrinsic cataly.ic activity. By.considering.the trade-off between the loading.amount and ECSA, the best HER performance is clearly.observed in the 200 W-15 min sample with an overpotential of 220 mV at a current density.of 10 mA cm-2. Such a simple sputtering.method at low temperature can be easily.expanded to other 2D TMD electrochemical cataly.ts, promising.potentially.practical electrocataly.ts.

~[he cing.lum, a long.neural tract extending.from the orbitof- rontal cortex to the medial temporal lobe, obtains cholinerg.c innervation from three cholinerg.c nuclei in the basal fore- brain （the nucleus basalis of Mey.ert [Ch 4], the medial septal nucleus [Ch 1 ], and the vertical nucleus of the diag.nal band [Ch 2]）, and is the passag. of the medial cholinerg.c pathway.which supplies cholinerg.c innervation from the basal forebrain to the cerebral cortex （Folstein et al., 1975; Selden et al., 1998; Lucas-Meunier et al., 2003）. Therefore, it is important for cog. nition, especially.memory.function （Selden et al., 1998）.

Several diffusion tensor-imag.ng.studies have demonstrated motor recovery.mechanisms in stroke patients with subcortical infarct, including.the corona radiata, pons, and medulla. However, studies of motor recovery.mechanisms have not been reported in patients with posterior limb infarcts of the intemal capsule. The present study.reports on a 77-y.ar-old man with complete paraly.is of the left extremities at stroke onset. At 6 months after onset, motor function of the left extremities recovered to a nearly.normal state. The 3-week diffusion tensor tractog.aphy.of the affected （rig.t） hemisphere showed that corticospinal tract discontinued below the posterior limb. In contrast, 6-month diffusion tensor tractog.aphy.revealed that the rig.t corticospinal tract orig.nated from the precentral g.0}us and descended along.the anterior area of the infarcted posterior limb. Motor function of the affected extremities was reorg.nized into the anterior area of the posterior limb infarct.

Coordinated movement is g.nerated by.communication between the cerebrum and cerebellum via the cerebellar peduncles (CPs). The CPs are classified into three ty.es (superior, middle, and inferior), and each includes a variety.of neural tracts. Among.those tracts, the cortico-ponto-cerebellar tract (CPCT), a middle CP, is involved in motor planning.and initiation of movement, while the dentato-rubro-thalamic tract (DRTT), a superior CP, is involved in motor coordination, movement timing. verbal fluency. and working.memory.(Kase et al., 1993.

Many.studies have attempted to elucidate the motor recovery.mechanism of stroke, but the majority.of these studies focus on cerebral infarct and relatively.little is known about the motor recovery.mechanism of intracerebral hemorrhag.. In this study. we report on a patient with intracerebral hemorrhag. who display.d a chang. in injured corticospinal tract orig.nating.from the premotor cortex to the primary.motor cortex on diffusion tensor imag.ng. An 86-y.ar-old woman presented with complete paraly.is of the rig.t extremities following.spontaneous intracerebral hemorrhag. in the left frontoparietal cortex. The patient showed motor recovery. to the extent of being.able to extend affected fing.rs ag.inst g.avity.and to walk independently.on even g.ound at 5 months after onset. Diffusion tensor imag.ng.showed that the left corticospinal tract orig.nated from the premotor cortex at 1 month after intracerebral hemorrhag. and from the left primary.motor cortex and premotor cortex at 5 months after intracerebral hemorrhag.. The chang. of injured corticospinal tract orig.nating.from the premotor cortex to the primary.motor cortex sug.ests motor recovery.of intracerebral hemorrhag..
