A case is reported of right-sided tonic pupil in isolation (Adie's pupil) following Le Fort I maxillary osteotomy. It is difficult to identify whether this rare finding immediately postoperatively is either a pure coincidence or a genuine complication of surgery.

Alteration of responses to salient stimuli occurs in a wide range of brain disorders and may be rooted in pathophysiological brain state dynamics. Specifically, tonic and phasic modes of activity in the reticular activating system (RAS) influence, and are influenced by, salient stimuli, respectively. The RAS influences the spectral characteristics of activity in the neocortex, shifting the balance between low- and high-frequency fluctuations.

Response inhibition is key to flexible behavior. Importantly, performance in any task, including response inhibition tasks, fluctuates on a moment-to-moment basis. Using pupillometry, we investigated the relationship between these behavioral fluctuations in response inhibition and naturally occurring fluctuations of norepinephrine (NE) levels in the brain before a given trial has even started.

Article Synopsis
- Entrainment theories suggest that attention alternates between being focused and disengaged, leading to possible benefits in tasks with rhythmic structures.
- In two experiments aimed at testing these theories through auditory tasks, the study found no advantages for rhythmic sequences over arrhythmic ones in terms of performance.
- Additionally, results indicated that arrhythmic conditions were associated with larger pupil sizes, implying increased processing demands, which challenges the broader applicability of entrainment theories in various experimental setups.
Pupil Trend Reflects Suboptimal Alertness Maintenance over 10 s in Vigilance and Working Memory Performance: An Exploratory Study.

Maintaining concentration on demanding cognitive tasks, such as vigilance (VG) and working memory (WM) tasks, is crucial for successful task completion. Previous research suggests that internal concentration maintenance fluctuates, potentially declining to suboptimal states, which can influence trial-by-trial performance in these tasks. However, the timescale of such alertness maintenance, as indicated by slow changes in pupil diameter, has not been thoroughly investigated.

Pupil size is a non-invasive index for autonomic arousal mediated by the locus coeruleus-norepinephrine (LC-NE) system. While pupil size and its derivative (velocity) are increasingly used as indicators of arousal, limited research has investigated the relationships between pupil size and other well-known autonomic responses. Here, we simultaneously recorded pupillometry, heart rate, skin conductance, pulse wave amplitude, and respiration signals during an emotional face-word Stroop task, in which task-evoked (phasic) pupil dilation correlates with LC-NE responsivity.
