Sentences with word «saccadic»

It not only measures the speed of rapid number naming, thus capturing impairment of saccadic eye movements, but the test - taker's balance, attention, language and visual recognition skills.
The resulting delicate drawings are reminiscent of web - like versions of abstract expressionist Philip Guston or Joan Mitchell, though the accompanying essay draws on Lacanian psychoanalytic theory while the gallery statement emphasizes the scientific use of saccadic movement studies in diagnosing neurological disorders.
Noudoost and the team studied saccadic eye movements — those movements where the eye jumps from one point of focus to another — in an effort to determine exactly how this happens without us being overcome by our brains processing too much visual information.
His current projects include elucidation of the cortical representation of oculomotor proprioception, using saccadic adaptation to understand the coordinate system of neurons in the lateral intraparietal area, the role of prestriate cortex in visual search, and the role of inhibition in the response of parietal neurons.
According to Noudoost, scientists have been trying to learn exactly how the brain processes these visual stimuli during saccadic eye movement and this research offers new evidence that the prefrontal cortex of the brain is responsible for visual stability.
By recording neuronal activity in monkeys as they performed tasks that caused saccades, Dr. Christopher Pack has shown that there are waves of activity that cross specific vision processing areas of the brain in defined patterns, and that these patterns are reorganized by saccadic eye movements.
It increased saccadic eye movement as babies anticipated where the forthcoming stimulus would appear.
In a purely retinotopic framework, activity prior to a central saccade should be minimal and irrelevant given that there is not a stimulus in the RF nor is that location a potential saccadic target (Figure 1).
Correlations between firing rate and saccade metrics (saccade velocity) were also calculated in order to determine if LIP activity was related to saccadic motor output.
We found that the overall population activity was not significantly correlated to saccadic velocity (p > 0.05).
Here, we demonstrate how the brainstem can be linear, and how instead the midbrain superior colliculus (SC) could optimize saccadic speed - accuracy tradeoff.
Albeit an unfolded textbook, NG, Time, Economist,... Scientist and most mags are 18 ″... that's how our brains (eye + neural net, see visual integration across saccadic eye movements) read pages: Unfolded, scanning back - forth, diagonal, reverse... and again.
The results provoke the viewer to engage in an active participatory role, as the gaze conflates the static physicality of the canvas with the natural saccadic movement of vision.
The stimulus - driven, reflexive attention and saccadic eye movement of those babies born via a caesarean were found to be slowed compared to those of vaginally delivered infants.
Studies show that saccadic movements - the quick eye movements used in reading - are frequently abnormal following concussion and may predict whether an athlete will suffer from postconcussion syndrome (e.g. symptoms which persist over a long period of time, instead of clearing within the first 7 to 10 days, as in the vast majority of cases)(over 90 % in one recent study).
This activated infants» saccadic (or quick, jerky) eye movement, so that their eyes turned faster towards the place where a target was subsequently presented.
Specifically, we looked at whether activity locked to a particular saccade could completely explain the peri-saccadic activity aligned to the other saccade by generating firing rate predictions of each saccadic alignment on the basis of the other (Figure 5A) and behavioral variability.
Recent discoveries in the laboratory include the demonstration of a predictive relationship of parietal activity to both saccadic reaction time and visual attention.
He also demonstrated that the lateral parietal area acts as a linear summing junction for at least three independent signals: a saccadic signal, undifferentiated visual signal, and a cognitive signal.
The results of saccadic function were available for 64 children of whom 62 had accurate saccades, with one child demonstrating an undershoot, and one with an overshoot of the saccadic endpoint.
