Perspective: Depression in Persons with Parkinson's Disease

Movement Disorders, EarlyView.
Abstract Depression is a prevalent and disabling syndrome characterized by sustained sadness and/or anhedonia, as well as cognitive and physical symptoms. In Parkinson's disease (PD), depression is both common and clinically challenging due to overlapping symptoms and complex etiologic interactions. Major depressive disorder occurs in approximately 17%

A multi-stage recurrent neural network better describes decision-related activity in dorsal premotor cortex [PDF]

, 2019
We studied how a network of recurrently connected artificial units solve a visual perceptual decision-making task. The goal of this task is to discriminate the dominant color of a central static checkerboard and report the decision with an arm ...

The relationship between resting-state functional connectivity, antidepressant discontinuation and depression relapse

Scientific Reports, 2020
The risk of relapsing into depression after stopping antidepressants is high, but no established predictors exist. Resting-state functional magnetic resonance imaging (rsfMRI) measures may help predict relapse and identify the mechanisms by which ...

Efficacy and safety of transcranial direct current stimulation in alcohol use disorder: A randomized controlled triple‐blind trial

Addiction, EarlyView.
Abstract Background and aims Current treatment options for alcohol use disorder are limited. Transcranial direct current stimulation has been proposed as a therapeutic approach, but evidence remains scarce. This study aimed to compare active vs. sham transcranial direct current stimulation to evaluate its efficacy and safety in reducing alcohol ...

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

, 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.

Effects of postural intervention using a risshin chair on physical posture, class time perception, and subjective well‐being in junior high school students

British Journal of Educational Psychology, EarlyView.
Abstract Background Research based on embodied cognition has demonstrated that physical posture, particularly an upright seated posture, can influence emotions and cognition. However, although students spend most of the day sitting in classrooms, intervention research on upright seated postures suitable for learning environments is limited.

Different prefrontal cortex activity patterns in bipolar and unipolar depression during verbal fluency tasks based on functional near infrared spectroscopy study

Scientific Reports
This study aimed to investigate the functionality of the prefrontal cortex in patients with unipolar depression (UD) and bipolar depression (BD) using functional near-infrared spectroscopy (fNIRS) during a verbal fluency task (VFT).

Common and Distinct Functional Brain Networks for Intuitive and Deliberate Decision Making [PDF]

, 2019
Reinforcement learning studies in rodents and primates demonstrate that goal-directed and habitual choice behaviors are mediated through different fronto-striatal systems, but the evidence is less clear in humans.

The developmental trajectories of working memory updating from early childhood to adolescence: A meta‐analysis

British Journal of Psychology, EarlyView.
Abstract Working memory updating is a crucial cognitive function for learning and academic achievement that develops significantly throughout childhood and adolescence. Despite the varieties of existing tasks to measure children's working memory updating, its overall developmental trajectory and task‐specific developmental patterns remain inadequately ...

Distinct Roles of the Prefrontal and Posterior Parietal Cortices in Response Inhibition

Cell Reports, 2016
The dorsolateral prefrontal cortex and posterior parietal cortex have been implicated in the planning of movements and inhibition of inappropriate responses, though their precise roles in these functions are not known.
