Functional brain organization of macaque monkeys and humans was directly compared by functional magnetic resonance imaging. Subjects of both species performed a modified Wisconsin Card Sorting Test that required behavioral flexibility in the form of cognitive set shifting. Equivalent visual stimuli and task sequence were used for the two species. We found(More)
Functional organization of human cerebral hemispheres is asymmetrically specialized, most typically along a verbal/nonverbal axis. In this event-related functional MRI study, we report another example of the asymmetrical specialization. Set-shifting paradigms derived from the Wisconsin card sorting test were used, where subjects update one behavior to(More)
Rapid presentation event-related functional magnetic resonance imaging was applied to macaque monkeys performing a symmetrically rewarded go/no-go task, to investigate neural correlate of response inhibition. Sensorimotor activation related to the task performance was observed predominantly in the hemisphere contralateral to the response forelimb.(More)
Stop-signal task (SST) has been a key paradigm for probing human brain mechanisms underlying response inhibition, and the inhibition observed in SST is now considered to largely depend on a fronto basal ganglia network consisting mainly of right inferior frontal cortex, pre-supplementary motor area (pre-SMA), and basal ganglia, including subthalamic(More)
Hereditary spastic paraplegia (HSP) is one of the most genetically heterogeneous neurodegenerative disorders characterized by progressive spasticity and pyramidal weakness of lower limbs. Because >30 causative genes have been identified, screening of multiple genes is required for establishing molecular diagnosis of individual patients with HSP. To(More)
Substance P is speculated to be a key mediator of itching in atopic dermatitis, possibly acting via the tachykinin NK1 receptor. Thus, we examined the effect of a tachykinin NK1 antagonist, BIIF 1149 CL, on scratching behaviour in a picrylchloride-induced dermatitis model in NC/Nga mice. BIIF 1149 CL ((S)-N-[2-[3,5-bis(trifluoromethyl)(More)
BACKGROUND Atopic dermatitis (AD) can be exacerbated or induced in genetically predisposed individuals by psychological stress, which causes the release of substance P (SP). Therefore, SP may play an etiological role in the mechanisms underlying AD. METHODS Changes in the number of mast cells and SP-containing mast cells in lesional skin, and the serum(More)
The purpose of this study was to investigate the renoprotective effect of telmisartan on the advanced stages of nephropathy in rats with 5/6 nephrectomy (5/6 Nx). Telmisartan was orally administered for 12 weeks to rats that previously underwent 5/6 Nx or sham operations. After completion of the administration period, the degree of renal injury was examined(More)
The effect of a blocking-antibody specific for lymphocyte function-associated antigen-1 (LFA-1) was studied in an atopic-like dermatitis model, which was induced by the repeated application of picrylchloride in NC/Nga mice. Prophylactic treatment with anti-LFA-1 monoclonal antibody (mAb), not therapeutic treatment, significantly inhibited the skin severity(More)
Familial amyloidosis of the Finnish type (FAF) is an autosomal dominant form of systematic amyloidosis characterized by lattice corneal dystrophy, cranial neuropathy, and cutis laxa. Although FAF has been frequently found in the Finnish population, FAF is a considerably rare disorder in other regions. In this study, we examined the clinical characteristics(More)
