Neural coding of tactile decisions in the human prefrontal cortex [PDF]

, 2006
The neural processes underlying tactile decisions in the human brain remain elusive. We addressed this question in a functional magnetic resonance imaging study using a somatosensory discrimination task, requiring participants to compare the frequency of

Progressive Prefrontal Cortex Dysfunction in Parkinson's Disease With Probable REM Sleep Behavior Disorder: A 3-Year Longitudinal Study

Frontiers in Aging Neuroscience, 2022
This study aimed to explore the disrupted prefrontal cortex activity specific to patients with Parkinson's disease (PD) with rapid eye movement sleep behavior disorder (RBD) compared with those without and to further examine the associations between ...

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 Neurobase of ambiguity loss aversion about decision making

Frontiers in Psychology, 2023
In our daily decision-making, there are two confusing problems: risk and ambiguity. Many psychological studies and neuroscience studies have shown that the prefrontal cortex (PFC) is an important neural mechanism for modulating the human brain in risk ...

Functional differentiation within the monkey cortex as revealed by near-infrared spectroscopy [PDF]

, 2008
The role of prefrontal cortex in working memory (WM) is well established. However, questions remain regarding the topography and “domain-specific differentiation” of different types of information processing in the cortex.

A single 1,500 m freestyle at maximal speed decreases cognitive function in athletes

Frontiers in Psychology, 2023
IntroductionPhysical exercise can improve cognitive function, and the degree of impact on cognitive function is related to exercise modality, intensity, and duration.

Groove rhythm stimulates prefrontal cortex function in groove enjoyers

Scientific Reports, 2022
Hearing a groove rhythm (GR), which creates the sensation of wanting to move to the music, can also create feelings of pleasure and arousal in people, and it may enhance cognitive performance, as does exercise, by stimulating the prefrontal cortex. Here,

What Does Sleeping Brain Tell About Stress? A Pilot Functional Near-Infrared Spectroscopy Study Into Stress-Related Cortical Hemodynamic Features During Sleep

Frontiers in Computer Science, 2021
People with mental stress often experience disturbed sleep, suggesting stress-related abnormalities in brain activity during sleep. However, no study has looked at the physiological oscillations in brain hemodynamics during sleep in relation to stress ...

Specialization of the rostral prefrontal cortex for distinct analogy processes [PDF]

, 2010
Analogical reasoning is central to learning and abstract thinking. It involves using a more familiar situation (source) to make inferences about a less familiar situation (target).
