Article Abstract
Macaque inferior temporal cortex neurons respond selectively to complex visual images, with recent work showing that they are also entrained reliably by the evolving content of natural movies. To what extent does temporal continuity itself shape the responses of high-level visual neurons? We addressed this question by measuring how cells in face-selective regions of the macaque visual cortex were affected by the manipulation of a movie's temporal structure. Sampling a 5-min movie at 1 s intervals, we measured neural responses to randomized, brief stimuli of different lengths, ranging from 800 ms dynamic movie snippets to 100 ms static frames. We found that the disruption of temporal continuity strongly altered neural response profiles, particularly in the early response period after stimulus onset. The results suggest that models of visual system function based on discrete and randomized visual presentations may not translate well to the brain's natural modes of operation.

Predicting mortality dynamics in cancer patients: A machine learning approach to pre-death events.

Capturing the dynamic changes in patients' internal states as they approach death due to fatal diseases remains a major challenge in understanding individual pathologies and improving end-of-life care. However, existing methods primarily focus on specific test values or organ dysfunction markers, failing to provide a comprehensive view of the evolving internal state preceding death. To address this, we analyzed electronic health record (EHR) data from a single institution, including 8,976 cancer patients and 77 laboratory parameters, by constructing continuous mortality prediction models based on gradient-boosting decision trees and leveraging them for temporal analyses.

Although glutamatergic and GABAergic synapses are important in seizure generation, the contribution of non-synaptic ionic and electrical mechanisms to synchronization of seizure-prone hippocampal neurons remains unclear. Here, we developed a physiologically relevant model to study these mechanisms by inducing prolonged seizure-like discharges (SLDs) in hippocampal slices from male rats through modest, sustained ionic manipulations. Specifically, we reduced extracellular calcium to 0.

Thus, we aimed to describe the current status of CRRT in Japan through a multicenter retrospective observational study.
Methods: Adult ICU patients receiving CRRT at 18 tertiary hospitals in Japan (up to 100 patients from each hospital over the past year) were retrospectively enrolled.
Segmenting the motion components of a video: A long-term unsupervised model.
IEEE Trans Pattern Anal Mach Intell
September 2025
Human beings have the ability to continuously analyze a video and immediately extract the motion components. We want to adopt this paradigm to provide a coherent and stable motion segmentation over the video sequence. In this perspective, we propose a novel long-term spatio-temporal model operating in a totally unsupervised way.

Echolocating bats provide vital ecosystem services and can be monitored effectively using passive acoustic monitoring (PAM) techniques. Duty-cycle subsampling is widely used to collect PAM data at regular ON/OFF cycles to circumvent battery and storage capacity constraints for long-term monitoring. However, the impact of duty-cycle subsampling and potential detector errors on estimating bat activity has not been systematically investigated for bats.
