Prior Expectations Bias Confidence Judgments Through Parietal Alpha‐Band Modulation

Advanced Science, EarlyView.
ABSTRACT Humans possess the metacognitive ability to estimate the likely accuracy of their own decisions through confidence judgments. Yet, whether prior information shapes confidence and the neural mechanisms mediating such influence, remain to be determined.

A review of impaired neuroplasticity in schizophrenia investigated with non-invasive brain stimulation

Frontiers in Psychiatry, 2016
Background: Several lines of evidence implicate dysfunctional neuronal plasticity in the pathophysiology of schizophrenia. Aberrant glutamatergic and gamma amino-butyric acid neurotransmission are thought to underlie core cognitive deficits and negative ...

An On‐Demand Neuromorphic Vision System Enabled by a Multi‐Paradigm Neuromorphic Device and Hierarchical Reconfigurability Designed from Device to System Level

Advanced Science, EarlyView.
An on‐demand ultra‐reconfigurable intelligent vision system with hierarchical reconfigurability from device to system levels is demonstrated. Through co‐design of a multi‐paradigm device, reconfigurable circuits, and adaptive system architecture/algorithms, the system enables seamless switching among spiking, non‐spiking, neuromorphic imaging (NI), and

Synaptic plasticity onto inhibitory neurons as a mechanism for ocular dominance plasticity.

PLoS Computational Biology, 2019
Ocular dominance plasticity is a well-documented phenomenon allowing us to study properties of cortical maturation. Understanding this maturation might be an important step towards unravelling how cortical circuits function.

Plasticity in the visual system is associated with prosthesis use in phantom limb pain

Frontiers in Human Neuroscience, 2013
The experience of strong phantom limb pain (PLP) in arm amputees was previously shown to be associated with structural neural plasticity in parts of the cortex that belong to dorsal and ventral visual streams.

Reversal of LTP-Like cortical plasticity in Alzheimer's disease patients with tau-related faster clinical progression

, 2015
Cerebrospinal fluid (CSF) concentrations of amyloid-β (Aβ), total tau (t-tau), and phosphorylated tau proteins are associated with different clinical progression in Alzheimer's disease (AD).

Personalized Network‐Guided Neuromodulation Enhances Human Working Memory

Advanced Science, EarlyView.
A personalized neuromodulation framework combining individualized functional brain network targeting with real‐time neural decoding is introduced. Using concurrent TMS–fMRI, participant‐specific stimulation targets and optimal frequencies are identified. Only optimal‐frequency stimulation improves working memory across sessions.

A cortical disinhibitory circuit for enhancing adult plasticity

eLife, 2015
The adult brain continues to learn and can recover from injury, but the elements and operation of the neural circuits responsible for this plasticity are not known.

Understanding and Optimizing Vagus Nerve Stimulation Directed Cortical Plasticity

, 2018
Vagus nerve stimulation (VNS) is a tool that has been used to treat epilepsy, depression and enhance memory. In the last few years VNS has been observed to direct cortical plasticity when paired with a sensory or motor event.

Altered cortical plasticity and connectivity in unaffected first-degree relatives of patients with schizophrenia

, 2019
Content: Impaired cortical plasticity and brain dysconnectivity are discussed to be essential pathomechanisms of schizophrenia. NMDA receptors, glutamate and intracellular calcium concentration play a key role in this regard.
