Torsion points on theta divisors
(American Mathematical Society, 2017)
© 2016 American Mathematical Society. Using the irreducibility of a natural irreducible representation of the theta group of an ample line bundle on an abelian variety, we derive a bound for the number of n-torsion points ...
Modulation of frequency preference in heterogeneous populations of theta-resonant neurons
(Pergamon-Elsevier, 2020)
Neurons from several brain regions resonate in the theta frequency range (4-12 Hz), displaying a higher voltage response to oscillatory currents at a preferred 'resonant' frequency (f(R)). Subthreshold resonance could ...
Theta divisors whose Gauss map has a fiber of positive dimension
(Elsevier, 2020)
We construct families of principally polarized abelian varieties whose theta divisor is irreducible and contains an abelian subvariety. These families are used to construct examples when the Gauss map of the theta divisor ...
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 ...
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 ...
Specific Impairment of “What-Where-When” Episodic-Like Memory in Experimental Models of Temporal Lobe Epilepsy
(2013)
Episodic memory deficit is a common cognitive disorder in human temporal lobe epilepsy (TLE). However, no animal model of TLE has
been shown to specifically replicate this cognitive dysfunction, which has limited its ...
Perfect Brewster transmission through ultrathin perforated films
(Elsevier, 2020)
We address the perfect transmission of a plane acoustic wave at oblique incidence on a perforated, sound penetrable or rigid, film in two-dimensions. It is shown that the Brewster incidence theta* realizing so-called ...
Optogenetic inactivation of the medial septum impairs long-term object recognition memory formation
(Reino Unido, 2022-06-07)
Theta is one of the most prominent extracellular synchronous oscillations in the mammalian brain. Hippocampal theta relies on an intact medial septum (MS) and has been consistently recorded during the training phase of ...
The olfactory bulb theta rhythm follows all frequencies of diaphragmatic respiration in the freely behaving rat
(2014)
Sensory-motor relationships are part of the normal operation of sensory systems. Sensing occurs in the context of active sensor movement, which in turn influences sensory processing. We address such a process in the rat ...
Brain to brain coupling in the gamma band as a marker of shared intentionality
(Frontiers Media, 2020)
Cooperation and competition are two ways of social interaction keys to life in society. Recent EEG-based hyperscanning studies reveal that cooperative and competitive interactions induce an increase in interbrain coupling. ...
