Causal contributions of left inferior and medial frontal cortex to semantic and executive control
Communications BiologySemantic control enables context-guided retrieval from memory, yet its distinction from domain-general executive control remains debated. We applied transcranial magnetic stimulation (TMS) to the left inferior frontal gyrus (IFG) and pre-supplementary ...

Physical Exercise as an Epigenetic Modulator of Brain Plasticity and Cognition
Neuroscience and Biobehavioral Reviews, 2017 A large amount of evidence has demonstrated the power of exercise to support cognitive function, the effects of which can last for considerable time. An emerging line of scientific evidence indicates that the effects of exercise are longer lasting than ...

Morphological plasticity of astroglia: Understanding synaptic microenvironment
, 2015 Memory formation in the brain is thought to rely on the remodeling of synaptic connections which eventually results in neural network rewiring. This remodeling is likely to involve ultrathin astroglial protrusions which often occur in the immediate ...

Advanced Functional Materials, EarlyView.In MOCVD MoS2 memristors, a current compliance‐regulated Ag filament mechanism is revealed. The filament ruptures spontaneously during volatile switching, while subsequent growth proceeds vertically through the MoS2 layers and then laterally along the van der Waals gaps during nonvolatile switching.

The actin-binding protein profilin II in neuronal plasticity [PDF]
, 2006 Activity-dependent plasticity in neurons involves changes in synaptic transmission and connectivity. These changes lead to altered neuronal circuit properties and are thought to underlie learning and memory.

Lifelong cortical myelin plasticity and age-related degeneration in the live mammalian brain
Nature Neuroscience, 2018 Axonal myelin increases neural processing speed and efficiency. It is unknown whether patterns of myelin distribution are fixed or whether myelinating oligodendrocytes are continually generated in adulthood and maintain the capacity for structural ...

Advanced Functional Materials, EarlyView.Optoelectronic synaptic devices based on solution‐processed molecular telluride GST‐225 phase‐change inks are demonstrated for three‐factor learning. A global optical signal broadcast through a silicon waveguide induces non‐volatile conductance updates exclusively in locally electrically flagged memristors.

Current Opinion in Neurobiology, 2019 Synaptic plasticity is the cellular basis of learning and memory, but to what extent this holds for the adult human brain is not known. To study synaptic plasticity in human neuronal circuits poses a huge challenge, since live human neurons and synapses ...
