Model-Based Decision Making in the Human Brain [PDF]

, 2007
Many real-life decision making problems incorporate higher-order structure, involving interdependencies between different stimuli, actions, and subsequent rewards.

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.

More subjects are required for ventrolateral than dorsolateral prefrontal TMS because of intolerability and potential drop-out.

PLoS ONE, 2019
Transcranial magnetic stimulation (TMS) of the human lateral prefrontal cortex, particularly the ventral region, often causes considerable discomfort to subjects.

Altered Functional Segregated Sensorimotor, Associative, and Limbic Cortical-Striatal Connections in Parkinson's Disease: An fMRI Investigation

Frontiers in Neurology, 2021
Multiple studies have identified segregated functional territories in the basal ganglia for the control of goal-directed and habitual actions. It has been suggested that in PD, preferential loss of dopamine in the posterior putamen may cause a major ...

Methamphetamine-Triggered Neurotoxicity in Human Dorsolateral Prefrontal Cortex

Galen Medical Journal, 2021
Background: Methamphetamine (MA), is an extremely addictive stimulant that adversely affects the central nervous system. Accumulating evidence indicates that molecular mechanisms such as oxidative stress, apoptosis, and autophagy are involved in the toxicity of MA.

Overlapping functional anatomy for working memory and visual search [PDF]

, 2009
Recent behavioural findings using dual-task paradigms demonstrate the importance of both spatial and non-spatial working memory processes in inefficient visual search (Anderson et al. in Exp Psychol 55:301-312, 2008).

Perturbation of the right prefrontal cortex disrupts interference control

NeuroImage, 2020
Resolving cognitive interference is central for successful everyday cognition and behavior. The Stroop task is a classical measure of cognitive interference.
