Comparison of Strategy Signals in the Dorsolateral and Orbital Prefrontal Cortex [PDF]

The Journal of Neuroscience, 2011
Abstract behavior-guiding rules and strategies allow monkeys to avoid errors in rarely encountered situations. In the present study, we contrasted strategy-related neuronal activity in the dorsolateral prefrontal cortex (PFdl) and the orbital prefrontal cortex (PFo) of rhesus monkeys.

Effects of frontal transcranial direct current stimulation on emotional processing and mood in healthy humans

Frontiers in Psychiatry, 2012
The prefrontal cortex is involved in mood and emotional processing. In patients suffering from depression, the left dorsolateral prefrontal cortex is hypoactive, while activity of the right dorsolateral prefrontal cortex is enhanced.

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.

Resting-state coupling between core regions within the central-executive and salience networks contributes to working memory performance

Frontiers in Behavioral Neuroscience, 2016
Previous studies investigated the distinct roles played by different cognitive regions and suggested that the patterns of connectivity of these regions are associated with working memory.

Larger mid-dorsolateral prefrontal gray matter volume in young binge drinkers revealed by voxel-based morphometry.

PLoS ONE, 2014
Binge drinking or heavy episodic drinking is a high prevalent pattern of alcohol consumption among young people in several countries. Despite increasing evidence that binge drinking is associated with impairments in executive aspects of working memory (i.

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).

Quantitative 3.0T MR spectroscopy reveals decreased creatine concentration in the dorsolateral prefrontal cortex of patients with social anxiety disorder. [PDF]

PLoS ONE, 2012
BACKGROUND: The brain biochemical changes of social anxiety have not been clarified although there have been a limited number of MR spectroscopic studies which utilized metabolite/creatine ratios. Present study aimed to explore the alteration of absolute

Functional specialization within rostral prefrontal cortex (Area 10): a meta-analysis [PDF]

, 2006
One of the least well understood regions of the human brain is rostral prefrontal cortex, approximating Brodmann's area 10. Here, we investigate the possibility that there are functional subdivisions within this region by conducting a meta-analysis of ...

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

Impairment of Neuroplasticity in the Dorsolateral Prefrontal Cortex by Alcohol

Scientific Reports, 2017
Abstract Previous studies have demonstrated that alcohol consumption impairs neuroplasticity in the motor cortex. However, it is unknown whether alcohol produces a similar impairment of neuroplasticity in the dorsolateral prefrontal cortex (DLPFC), a brain region that plays an important role in cognitive functioning.
