Viral encephalitis and seizures cause rapid depletion of neuronal progenitor cells and alter neurogenesis in the adult mouse dentate gyrus.

Infections impacting the central nervous system (CNS) constitute a substantial predisposing factor for the emergence of epileptic seizures. Given that epilepsy conventionally correlates with hippocampal sclerosis and neuronal degeneration, a potentially innovative avenue for therapeutic intervention involves fostering adult neurogenesis, a process primarily occurring within the subgranular zone of the dentate gyrus (DG) through the differentiation of neural stem cells (NSC). While experimental seizures induced by chemoconvulsants or electrical stimulation transiently enhance neurogenesis, the effects of encephalitis and the resultant virus-induced seizures remain inadequately understood.

Spatio-temporal patterns of tigers in response to prey species and anthropogenic activities.

Understanding factors influencing the spatio-temporal patterns of apex predators is prerequisite for their conservation. We studied space use and diel activity of tigers () in response to prey availability and anthropogenic activities with trail cameras in Nepal during December 2022-March 2023. We used hierarchical occupancy models to evaluate how prey availability (space use of prey species) and anthropogenic activities (number of humans and livestock) contributed to the tigers' space use, while accounting for landscape effects on their detection probability.

Population variability across geographical ranges: perspectives and challenges.

Populations fluctuate over time and across geographical space, and understanding how different factors contribute to population variability is a central goal in population ecology. There is a particular interest in identifying trends of population variability within geographical ranges as population densities of species can fluctuate substantially across geographical space. A common assumption is that populations vary more near species geographical range edges because of unsuitable environments and higher vulnerability to environmental variability in these areas.

Active control over exploration improves memory in toddlers.

Across two experiments, we implemented a novel gaze-contingent eye-tracking paradigm to investigate the early emergence of memory benefits from active control over exploration and to examine how exploratory behaviours affect memory formation in early development. Toddlers (experiment 1: = 36, 18-36 months; experiment 2: = 41, 23-36 months) were either allowed to actively control their exploration (active condition) or presented with the same information that they could only passively observe (passive condition in experiment 1; yoked condition in experiment 2). They were then tested in a preferential-looking paradigm in which familiar versus novel stimuli were presented in pairs.
