Many previous studies have used the presentation of multiple stimuli in the receptive fields (RFs) of visual cortical neurons to explore how neurons might operate on multiple inputs. Most of these experiments have used two fixed stimulus locations within the RF of each neuron. Here the effects of using different positions within the RF of a neuron were explored. The stimuli were presented singl...

A number of studies have highlighted the sophistication of corrective responses in lengthened muscles during the long-latency epoch. However, in various contexts, unloading can occur, which requires corrective actions from a shortened muscle. Here, we investigate the sophistication of inhibitory responses in shortened muscles due to unloading. Our first experiment quantified the inhibitory resp...

Moro response in healthy term newborns were studied to determine latency interval, time taken for optimal response (embracing movement of arms), and total duration of reflex response. Latency interval for onset of response was 0.41-0.49. Time taken for optimal response was 0.910-1.041s. Total duration of Moro response was 2.34 -2.59 s. Values were similar for males and females. Optimal response...

The frontocentral P3 event-related potential has been proposed as a neural marker of response inhibition. However, this association is disputed: some argue that P3 latency is too late relative to the timing of action stopping (stop-signal reaction time; SSRT) to index response inhibition. We tested whether P3 onset latency is a marker of response inhibition, and whether it coincides with the ti...

Superior response inhibition is an essential component of the advanced cognitive abilities of gifted children. This study investigated response inhibition in intellectually gifted children by recording event-related brain potentials (ERPs) during a Go/NoGo task. Fifteen intellectually gifted children and 15 intellectually average children participated. Our present findings showed that intellect...

introduction: noonan syndrome (ns) is a heterogeneous genetic disease that affects many parts of the body. it was named after dr. jacqueline anne noonan, a paediatric cardiologist.case report: we report audiological tests and auditory brainstem response (abr) findings in a 5-year old malay boy with ns. despite showing the marked signs of ns, the child could only produce a few meaningful words. ...

introduction: the brain glutamate neurotransmitter system and its nmda receptors in the nucleus accumbens play an important role in the incidence of the phenomena of sensitivity and addiction. the present study examined the inhibitory effect of glutamate nmda receptors in the nucleus accumbens in response to chronic stress. methods: after the unilateral and bilateral cannula placement in the nu...

Endophenotypes or intermediate phenotypes are of great interest in neuropsychiatric genetics because of their potential for facilitating gene discovery. We evaluated response inhibition, latency and variability measures derived from the stop task as endophenotypes of ADHD by testing whether they were related to ADHD traits in the general population, heritable and shared genetic risk with ADHD t...

Latency is a key service factor for user satisfaction. Consistency is in a trade-off relation with operation latency in the distributed and replicated scenario. Existing NoSQL stores guarantee either strong or weak consistencies but none provides the best consistency based on the response latency. In this paper, we introduce dConssandra, a NoSQL store enabling users to specify latency bounds fo...
