A claustrum in reptiles and its role in slow-wave sleep
The mammalian claustrum, owing to its widespread connectivity with other forebrain
structures, has been hypothesized to mediate functions that range from decision-making to …

Hippocampal ripples down-regulate synapses
The specific effects of sleep on synaptic plasticity remain unclear. We report that mouse
hippocampal sharp-wave ripple oscillations serve as intrinsic events that trigger long-lasting …

Sleep sharp wave ripple and its functions in memory and synaptic plasticity
Z Zhou, H Norimoto - Neuroscience Research, 2023 - Elsevier
Memory is one of the fundamental cognitive functions of brain. The formation and consolidation
of memory depend on the hippocampus and sleep. Sharp wave ripple (SWR) is an …

[HTML][HTML] Ablation of microglia does not alter circadian rhythm of locomotor activity
…, R Kobayashi, S Ito, S Nagashima, Z Zhou, H Norimoto - Molecular brain, 2023 - Springer
Microglia, as macrophages in the brain, are responsible for immune responses and synaptic
remodeling. Although the function of microglia is regulated by circadian rhythms, it is still …

[PDF][PDF] Visual cortical prosthesis with a geomagnetic compass restores spatial navigation in blind rats
H Norimoto, Y Ikegaya - Current Biology, 2015 - cell.com
Allocentric sense is one of the major components that underlie spatial navigation [1, 2]. In
blind patients, the difficulty in spatial exploration is attributed, at least partly, to the deficit of …
