Sustained dynamics of saccadic inhibition and adaptive oculomotor responses during continuous exploration In natural environments, stimuli often recur across time and space, requiring the visual system to remain sensitive to novelty while managing predictability. A central question in systems neuroscience...

When flashes interrupt vision, the eyes pause before moving again. That pause stays stable, but recovery weakens with repetition — the oculomotor system stays alert to novelty while cutting unnecessary eye movements to irrelevant events. 👉 www.biorxiv.org/content/10.1...

Left Area PF as a Neural Marker of Technical Reasoning Humans possess a unique capacity for technical reasoning - the ability to infer and manipulate the causal structure of the physical world. Although this faculty is central to technological innovation,...

🛠️🧠 How do we reshape the material world? Not by general intelligence alone, but through a specialized neural system: the left area PF fuels our capacity to reason about physical causality—core to tool use, invention, and cumulative culture.

Rethinking causal understanding and reverse engineering through the lens of cultural ecology

🌍🧠 What drives cultural invention? Not just imitation, but ecological reasoning: humans adapt, repurpose, and sometimes unknowingly reinvent—guided by environments shaped by others, not always by minds we understand.

Lack of pre-movement facilitation as neurophysiological hallmark of fatigue in patients with Parkinson's disease: A single pulse TMS study Fatigue is a debilitating symptom in Parkinson's disease (PD), significantly affecting quality of life. Despite its prevalence, the underlying neuroph…

In Parkinson’s disease, fatigue may reflect impaired motor preparation. 🔍

This TMS study shows absent pre-movement facilitation (PMF) in the most affected hemisphere of fatigued patients — a potential neurophysiological marker ⚡🧠

The Influence of Spatial Frequencies, Orientation and Familiarity on Face Stimuli Integration When we observe an object, our visual system identifies its shape and integrates it with specific details to form a coherent representation. This coarse-to-fine approach involves rapid processing of low spatial frequency (LSF) content to generate a basic template, which aids the integration of the more detailed high spatial frequency (HSF) information. Here we explore with two experiments how the contribution of LSF and HSF integration extends to face processing. To do so, we leveraged the face inversion effect, whereby inverted faces are more difficult to recognize than upright ones. In Experiment 1, ten participants matched two familiar faces displayed in rapid succession (template and probe face, respectively). The template and the probe shared either the same SF (congruent) or had complementary SF (incongruent). In congruent conditions, HSF templates yielded better matching accuracy than LSF templates. However, in incongruent conditions, mapping LSF probes onto HSF templates was more effective, but only for upright faces. We propose that, depending on the task, holistic processing may be facilitated by detailed information. In Experiment 2, twelve participants performed the same task with both familiar and unfamiliar faces. While for familiar faces the effects were the same as Experiment 1, for unfamiliar faces the overall accuracy was better for congruent than incongruent conditions, and, crucially, it was independent of the template SF. Our results challenge the view that LSF content provides a foundational template for integrating HSF information, and instead suggest a flexible encoding of SF information, that depends on image contingencies. ### Competing Interest Statement The authors have declared no competing interest.

🔍 Our brain processes faces using both coarse and fine details—but does LSF always guide perception? This study suggests a more flexible integration

Visual stimuli near eye movements can appear closer in time or even reversed—a known effect also seen with visual masks. Our findings show that visual masks not covering the stimuli can also trigger this temporal inversion, suggesting that mask onset time anchors perceptual organization.
