Prefrontal response and frontostriatal functional connectivity to monetary reward in abstinent alcohol-dependent young adults. [PDF]

open access: yesPLoS ONE, 2014
Although altered function in neural reward circuitry is widely proposed in models of addiction, more recent conceptual views have emphasized the role of disrupted response in prefrontal regions. Changes in regions such as the orbitofrontal cortex, medial

Distinct Neural Circuits Underlie Prospective and Concurrent Memory-Guided Behavior

open access: yesCell Reports, 2019
Summary: The past is the best predictor of the future. This simple postulate belies the complex neurobiological mechanisms that facilitate an individual’s use of memory to guide decisions. Previous research has shown integration of memories bias decision-

A functional magnetic resonance imaging study of pathophysiological changes responsible for mirror movements in Parkinson's disease. [PDF]

open access: yesPLoS ONE, 2013
Mirror movements correspond to involuntary movements observed in the limb contralateral to the one performing voluntary movement. They can be observed in Parkinson's disease (PD) but their pathophysiology remains unclear.

Overlapping functional anatomy for working memory and visual search

open access: yes, 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).

How predictable are spontaneous decisions and hidden intentions? Comparing classification results based on previous responses with multivariate pattern analysis of fMRI BOLD signals [PDF]

open access: yes, 2012
In two replication studies we examined response bias and dependencies in voluntary decisions. We trained a linear classifier to predict “spontaneous decisions” and in the second study “hidden intentions” from responses in preceding trials and achieved ...

Effects of rTMS conditioning over the fronto-parietal network on motor versus visual attention

open access: yes, 2007
Many studies have shown that visuospatial orienting attention depends on a network of frontal and parietal areas in the right hemisphere. Rushworth et al. [Rushworth, M. F., Krams, M., & Passingham, R. E. The attentional role of the left parietal cortex:

Prefrontal involvement in imitation learning of hand actions : effects of practice and expertise. [PDF]

open access: yes, 2007
In this event-related fMRI study, we demonstrate the effects of a single session of practising configural hand actions (guitar chords) on cortical activations during observation, motor preparation, and imitative execution.

Involvement of human amygdala and orbitofrontal cortex in hunger-enhanced memory for food stimuli [PDF]

open access: yes, 2001
We used positron emission tomography to measure regional cerebral blood flow (rCBF) in 10 healthy volunteers performing a recognition memory task with food and non-food items.

The role of the ventrolateral frontal cortex in inhibitory oculomotor control

open access: yes, 2007
It has been proposed that the inferior/ventrolateral frontal cortex plays a critical role in the inhibitory control of action during cognitive tasks.

The Role of the Dorsolateral Prefrontal Cortex during Sequence Learning is Specific for Spatial Information [PDF]

open access: yes, 2001
Many studies have implicated the dorsolateral prefrontal cortex in the acquisition of skill, including procedural sequence learning. However, the specific role it performs in sequence learning has remained uncertain.
