Interhemispheric asymmetry of the cerebral amino acid pool in rat with subtotal cerebral ischaemia
Анналы клинической и экспериментальной неврологии, 2019 The pathogenetic mechanisms of ischaemic stroke are complex and have not been fully studied, including the role of interhemispheric asymmetry in the brains biochemical organization. Study objective.

Journal of Neuroscience, 2017 The role of the frontal cortex in consciousness remains a matter of debate. In this Perspective, we will critically review the clinical and neuroimaging evidence for the involvement of the front versus the back of the cortex in specifying conscious ...

Frontiers in Neuroscience, 2020 Transcranial direct current stimulation (tDCS) is a non-invasive technique that modulates the neuronal membrane potential. We have previously documented a sustainable increase in extracellular dopamine levels in the rat striatum of cathodal tDCS ...

Parvalbumin-expressing basal forebrain neurons mediate learning from negative experience
Nature CommunicationsParvalbumin (PV)-expressing GABAergic neurons of the basal forebrain (BFPVNs) were proposed to serve as a rapid and transient arousal system, yet their exact role in awake behaviors remains unclear.

Recurrent inhibition in the cerebral cortex [PDF]
Neuroscience Letters, 2019 Neuronal activity can be modulated by endogenous control mechanisms that either facilitate or suppress it. With this idea in mind, we attempted to evaluate and correlate spinal neuronal activity with the amplitude of corticogram (ECoG) event related potentials (ERP) in the presence of nociceptive stimulation in rats. We evaluated the ERP in response to

Regional differences in the coupling between resting cerebral blood flow and metabolism may indicate action preparedness as a default state. [PDF]
, 2008 Although most functional neuroimaging studies examine task effects, interest intensifies in the "default" resting brain. Resting conditions show consistent regional activity, yet oxygen extraction fraction constancy across regions.

Cerebral cortex expansion and folding: what have we learned?
EMBO Journal, 2016 One of the most prominent features of the human brain is the fabulous size of the cerebral cortex and its intricate folding. Cortical folding takes place during embryonic development and is important to optimize the functional organization and wiring of ...
