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.

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 ...

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 ...

No Effect of Cathodal Transcranial Direct Current Stimulation on Fear Memory in Healthy Human Subjects

Brain Sciences, 2016
Background: Studies have demonstrated that fear memories can be modified using non-invasive methods. Recently, we demonstrated that anodal transcranial direct current stimulation (tDCS) of the right dorsolateral prefrontal cortex is capable of enhancing ...

Trait anxiety and the neural efficiency of manipulation in working memory [PDF]

, 2012
The present study investigates the effects of trait anxiety on the neural efficiency of working memory component functions (manipulation vs. maintenance) in the absence of threat-related stimuli.
