We perceive our surrounding as a continuous stream of information. Yet, it is under debate, whether our brain processes the incoming information continuously or rather in a discontinuous way. In recent years, the idea of rhythmic perception has regained popularity, assuming that parieto-occipital alpha oscillations are the neural mechanism defining the rhythmicity of visual perception.

Research on unconscious processing has been a valuable source of evidence in psycholinguistics for shedding light on the cognitive architecture of language. The automaticity of syntactic processing, in particular, has long been debated. One strategy to establish this automaticity involves detecting significant syntactic priming effects in tasks that limit conscious awareness of the stimuli.

The dissociation between conscious and unconscious perception is one of the most relevant issues in the study of human cognition. While there is evidence suggesting that some stimuli might be unconsciously processed up to its meaning (e.g.

The World Health Organisation (WHO) has recently advocated new safe limits of annual exposure for the three pre-dominant pollutants: fine particulate matter (PM2.5), coarse particulate matter (PM10) and nitrogen dioxide; namely 5μg/m3, 15μg/m3 and 10gμ/m3 respectively.

- The study observes the single-celled organism *coeruleus* displaying habituation to mechanical stimuli, indicating basic learning capabilities even in simple cells, but the mechanism behind this learning is still unclear.
- Researchers developed a biochemistry-based model that explains how mechanoreceptors in *coeruleus* sense stimuli, leading to changes in cell behavior such as action potential generation and internalization of receptors, a process that could facilitate learning.
- Simulations based on this model successfully replicated key features of habituation, suggesting a link between receptor dynamics and response to stimuli, while new experiments confirmed predictions about habituation patterns in the cell.
