Hippocampus-cortex communication during sleep
(2020)
Sleep is critically involved in the formation of long-term memory and is thought to rely on a dialogue between hippocampus and neocortex. The communication between these structures has been proposed to be from the hippocampus ...
Spatial maps and oscillations in the healthy hippocampus of Octodon degus, a natural model of sporadic Alzheimer’s disease
(2022)
The Octodon degus is a South American rodent that is receiving increased attention as a potential model of aging and sporadic late-onset Alzheimer’s disease (AD). Impairments in spatial memory tasks in Octodon degus have ...
Cross-frequency phase-amplitude coupling between hippocampal theta and gamma oscillations during recall destabilizes memory and renders it susceptible to reconsolidation disruption
(USA, 2020-08-12)
Avoidance memory reactivation at recall triggers theta-gamma hippocampal phase amplitude coupling (hPAC) only when it elicits hippocampus-dependent reconsolidation. However, it is not known whether there is a causal ...
Reactivation-dependent amnesia for object recognition memory is contingent on hippocampal theta–gamma coupling during recall
(USA, 2021-12-15)
Hippocampal dopamine D1/D5 receptor-dependent destabilization is necessary for object recognition memory (ORM) updating through reconsolidation. Dopamine also regulates hippocampal theta and gamma oscillations, which are ...
Caracterização eletrofisiológica das oscilações delta e teta do hipocampo dorsal de ratos durante locomoção em esteira
(Universidade Federal do Rio Grande do NorteBrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM PSICOBIOLOGIA, 2020-06-09)
The hippocampal theta rhythm (6-10 Hz) has been extensively studied since the 1950’s. These
researches have shown that the theta rhythm is involved with cognitive functions, sensorymotor integration, paradoxical sleep and ...
Brain state-dependent recruitment of high-frequency oscillations in the human hippocampus
(2017-09)
Ripples are high-frequency bouts of coordinated hippocampal activity believed to be crucial for information transfer and memory formation. We used intracortical macro electrodes to record neural activity in the human ...
Critical role of canonical transient receptor potential channel 7 in initiation of seizures
(National Academy of Sciences, 2014-07)
Status epilepticus (SE) is a life-threatening disease that has been recognized since antiquity but still causes over 50,000 deaths annually in the United States. The prevailing view on the pathophysiology of SE is ...
