Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

FEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Eye gaze metrics reflect a shared motor representation for action observation and movement imagery [PDF]

, 2012
Action observation (AO) and movement imagery (MI) have been reported to share similar neural networks. This study investigated the congruency between AO and MI using the eye gaze metrics, dwell time and fixation number.

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Perception of Self-Moving Speed in Different Visual Cue and Viewpoint Conditions in Virtual Reality Environment

IEEE Access, 2023
The perception of geometric cues in virtual spaces differs from that in actual spaces due to the reduced amount of information available in virtual spaces.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

First-Person Neuroscience: A new methodological approach for linking mental and neuronal states

Philosophy, Ethics, and Humanities in Medicine, 2006
Though the brain and its neuronal states have been investigated extensively, the neural correlates of mental states remain to be determined. Since mental states are experienced in first-person perspective and neuronal states are observed in third-person ...

Close to you: embodied simulation for peripersonal space in primary somatosensory cortex. [PDF]

PLoS ONE, 2012
BACKGROUND: An increasing body of evidence has demonstrated that in contrast to the classic understanding the primary somatosensory cortex (SI) reflects merely seen touch (in the absence of any real touch on the own body).

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Social Space and the Question of Objectivity / Der soziale Raum und die Frage nach der Objektivität

Gestalt Theory, 2017
In speaking of the social dimensions of human experience, we inevitably become involved in the debate regarding how they are to be studied. Should we embrace the first-person perspective, which is that of the phenomenologists, and begin with the ...
