Causal relationships between brain and spinal motor neuron excitability during motor imagery: Using NIRS and evoked electromyogram study

NeuroImage: Reports, 2022
In this study, we elucidated the neural basis of motor imagery by using a powerful statistical method in addition to simultaneous brain and spinal measurements using NIRS and evoked electromyogram.

Frontopolar Cortex Interacts With Dorsolateral Prefrontal Cortex to Causally Guide Metacognition. [PDF]

Hum Brain Mapp
ABSTRACTAccurate metacognitive judgments about an individual's performance in a mental task require the brain to have access to representations of the quality and difficulty of first‐order cognitive processes. However, little is known about how accurate metacognitive judgments are implemented in the brain.

Prefrontal cortex contributions to controlled memory judgment : fMRI evidence from adolescents and young adults [PDF]

, 2012
Cortical regions supporting cognitive control and memory judgment are structurally immature in adolescents. Here we studied adolescents (13-15 y.o.) and young adults (20-22 y.o.) using a recognition memory paradigm that modulates cognitive control ...

The contribution of ventrolateral and dorsolateral prefrontal cortex to response reversal [PDF]

Behavioural Brain Research, 2008
Studies investigating response reversal consistently implicate regions of medial and lateral prefrontal cortex when reinforcement contingencies change. However, it is unclear from these studies how these regions give rise to the individual components of response reversal, such as reinforcement value encoding, response inhibition, and response change ...

TULP4, a novel E3 ligase gene, participates in neuronal migration as a candidate in schizophrenia

CNS Neuroscience &Therapeutics, EarlyView., 2023
Mutations identified from four SCZ pedigrees resulted in decreased TULP4 expression. Tulp4 knockdown caused delayed neuron migration in embryonic mice, and impaired cognition and prepulse inhibition in adult mice. These phenotypes may be related to TULP4 through its involvement in the formation of a novel E3 ubiquitin ligases.

The topology of connections between rat prefrontal and temporal cortices [PDF]

, 2015
Understanding the structural organization of the prefrontal cortex (PFC) is an important step toward determining its functional organization. Here we investigated the organization of PFC using different neuronal tracers.

Electrophysiological Heterogeneity of Fast-Spiking Interneurons: Chandelier versus Basket Cells [PDF]

, 2013
In the prefrontal cortex, parvalbumin-positive inhibitory neurons play a prominent role in the neural circuitry that subserves working memory, and alterations in these neurons contribute to the pathophysiology of schizophrenia.

Cough is dangerous:Neural correlates of implicit body symptoms associations

Frontiers in Psychology, 2016
The negative interpretation of body sensations (e.g., as sign of a severe illness) is a crucial cognitive process in pathological health anxiety (HA). However, little is known about the nature and the degree of automaticity of this interpretation bias ...

Prediction of movement intention using connectivity within motor-related network: An electrocorticography study. [PDF]

PLoS ONE, 2018
Most brain-machine interface (BMI) studies have focused only on the active state of which a BMI user performs specific movement tasks. Therefore, models developed for predicting movements were optimized only for the active state.

Physiological Dysfunction of the Dorsolateral Prefrontal Cortex in Schizophrenia Revisited [PDF]

Cerebral Cortex, 2000
Evidence implicates subtle neuronal pathology of the prefrontal cortex (PFC) in schizophrenia, but how this pathology is reflected in physiological neuroimaging experiments remains controversial. We investigated PFC function in schizophrenia using functional magnetic resonance imaging (fMRI) and a parametric version of the n-back working memory (WM ...
