It is not known how the brain decides to act on moving objects. We demonstrated previously that neurons in the macaque supplementary eye field (SEF) reflect the rule of ocular baseball, a go/nogo task in which eye movements signal the rule-guided interpretation of the trajectory of a target. In ocular baseball, subjects must decide whether to pursue a moving spot target with an eye movement aft...

Sclerosing epithelioid fibrosarcoma (SEF) is a clinicopathologically distinct variant of fibrosarcoma that is capable of recurrence and metastasis. Awareness of imaging features and histopathologic characteristics will be helpful for differential diagnosis from other common tumors. Here, we report a case of SEF metastasizing to the pancreas as a solitary mass mimicking primary pancreatic cancer...

Sclerosing epithelioid fibrosarcoma (SEF) is a rare and aggressive tumor for which no standardized treatment regimens are available. The occurrence of this tumor in children and adolescents has been rarely reported, especially in the head and neck region. Involvement of the neuraxis is reported only in a few patients. We report a case of a 13-year-old boy with SEF of the skull with intracranial...

We studied the effects of a pilot project that strengthened savings incentive mechanisms. The was established by Small Enterprise Foundation (SEF), leading microfinance institution based in South Africa. program introduced stimulus form Goal Card: clients subscribing to this (non-coercive) tool were required identify goal and commit regular payments reach it. experiment had quasi-natural approa...

Complex learned motor sequences can be composed of a combination of a small number of elementary actions. To investigate how the brain represents such sequences, we devised an oculomotor sequence task in which the monkey had to choose the target solely by the sequential context, not by the current stimulus combination. We found that many neurons in the supplementary eye field (SEF) became activ...

The degree of parallel processing in frontal cortex-basal ganglia circuits is a central and debated issue in research on the basal ganglia. To approach this issue directly, we analyzed and compared the corticostriatal projections of two principal oculomotor areas of the frontal lobes, the frontal eye field (FEF) and the supplementary eye field (SEF). We first identified cortical regions within ...

The time varying spatial properties of the evoked cerebral response to external stimuli depicts the characteristics of the excited neural circuitry for the specific sensory involved modality. These spatiotemporal features are reflected in the shape of the brain evoked response, and our aim is to quantitatively characterize individually anatomofunctional features for the somatosensory system (so...

novel IS-saccade mappings. The first correctly executed trial was ping of a set of stimuli onto a set of actions. Such learning termed the early phase of learning, which always occurred more epitomizes the behavioral flexibility that advanced mammals than two trials before trial 0. Correct trials 02 to /2 constituted bring to a rapidly changing environment: any stimulus or the middle phase, tri...

OBJECTIVE To characterise and quantify the EEG during sleep in healthy newborns in the early newborn period. METHODS Continuous multi-channel video-EEG data was recorded for up to 2 hours in normal newborns within 12 hours of birth. The total amount of active (AS) and quiet sleep (QS) was calculated in the first hour of recording. The EEG signal was quantitatively analysed for symmetry and sy...
