introduction: anethole is the main constituent of pimpinella anisum l. (anise), a herbaceous annual plant which has several therapeutic effects. in the folk medicine, anise is employed as an antiepileptic drug. specifically, this study was focused on the cellular effect of anethole, an aromatic compound in essential oils from anise and camphor. anethole has various physiological effects on the ...

BACKGROUND Learning processes or language development are only some of the cognitive functions that differ qualitatively between men and women. Gender differences in the brain structure seem to be behind these variations. Indeed, this sexual dimorphism at neuroanatomical level is accompanied unequivocally by differences in the way that aging and neurodegenerative diseases affect men and women b...

Abstract Full scale simulations of neuronal network models the brain are challenging due to high density connections between neurons. This contribution reports run times shorter than simulated span biological time for a full model local cortical microcircuit with explicit representation synapses on recent conventional compute node. Realtime performance is relevant robotics and closed-loop appli...

Mitochondrial dysfunction is a prominent feature of Alzheimer's disease (AD) neurons. In this study, we explored the involvement of an abnormal mitochondrial dynamics by investigating the changes in the expression of mitochondrial fission and fusion proteins in AD brain and the potential cause and consequence of these changes in neuronal cells. We found that mitochondria were redistributed away...

The effects of neuronal density on morphological and functional attributes of the evolving networks were studied in cultured dissociated hippocampal neurons. Plating at different densities affected connectivity among the neurons, such that sparse networks exhibited stronger synaptic connections between pairs of recorded neurons. This was associated with different patterns of spontaneous network...
