The topographic organization of cortical neurons is traditionally examined using histological procedures. Functional magnetic resonance imaging (fMRI) offers the potential noninvasively to detect interregional connectivity of human brain. In the brain, there is spontaneous firing of neurons even in the resting state. Such spontaneous firing will increase(More)
Recent evidence that the cerebellum is involved in perception and cognition challenges the prevailing view that its primary function is fine motor control. A new alternative hypothesis is that the lateral cerebellum is not activated by the control of movement per se, but is strongly engaged during the acquisition and discrimination of sensory information.(More)
To distinguish the neural systems of normal speech from those of stuttering, PET images of brain blood flow were probed (correlated voxel-wise) with per-trial speech-behaviour scores obtained during PET imaging. Two cohorts were studied: 10 right-handed men who stuttered and 10 right-handed, age- and sex-matched non-stuttering controls. Ninety PET blood(More)
Functional magnetic resonance imaging was used to identify the neural correlates of Chinese character and word reading. The Chinese stimuli were presented visually, one at a time. Subjects covertly generated a word that was semantically related to each stimulus. Three sorts of Chinese items were used: single characters having precise meanings, single(More)
PURPOSE To characterize the central nervous system (CNS) pathway for acupuncture stimulation in the human brain by using functional magnetic resonance (MR) imaging. MATERIALS AND METHODS Functional MR imaging of the whole brain was performed in two groups of nine healthy subjects during four stimulation paradigms: real acupuncture at acupoints ST.36 (on(More)
BACKGROUND To compare capecitabine/cisplatin with 5-fluorouracil/cisplatin as first-line treatment for advanced gastric cancer (AGC). PATIENTS AND METHODS In this randomised, open-label, phase III study, patients received cisplatin (80 mg/m(2) i.v. day 1) plus oral capecitabine (1000 mg/m(2) b.i.d., days 1-14) (XP) or 5-FU (800 mg/m(2)/day by continuous(More)
LBA4018 Background: The oral fluoropyrimidine capecitabine has proven efficacy and safety in colorectal and breast cancer. Phase II data in AGC suggested that XP would show comparable efficacy to a standard FP regimen, with potential safety and convenience advantages. This phase III study evaluated XP vs. FP in first-line AGC. METHODS Pts with previously(More)
The mouth representation of the human, primary motor cortex (M1) is not reliably identified by surface anatomy but may be reliably localized by means of spatial coordinates. For this report, three quantitative metanalyses were performed which jointly described the mean location, location variability and location-probability profiles of the human M1-mouth(More)
Severe acute respiratory syndrome (SARS), now known to be caused by a coronavirus, probably originated in Guangdong province in southern China in late 2002. The first major outbreak occurred in Guangzhou, the capital of Guangdong, between January and March 2003. This study reviews the clinical presentation, laboratory findings and response to four different(More)
Numerous functional magnetic resonance imaging (fMRI) data analysis strategies have been used by different laboratories to enhance the detection of brain activation. A consensus has not been achieved regarding the relative statistical power of different strategies. In this report, we compared several commonly-used data analysis strategies for conventional(More)
