Altered negative BOLD responses in the default-mode network during emotion processing in depressed subjects

, 2009
Studies using functional magnetic resonance imaging (fMRI) show predominant negative blood oxygenation level-dependent (BOLD) responses (NBRs) in regions of the default-mode network such as the pregenual anterior cingulate cortex, the ventromedial ...

Recruitment of the default mode network during a demanding act of executive control

eLife, 2015
In the human brain, a default mode or task-negative network shows reduced activity during many cognitive tasks and is often associated with internally-directed processes, such as mind wandering and thoughts about the self.

Network homogeneity reveals decreased integrity of default-mode network in ADHD

, 2008
Examination of spontaneous intrinsic brain activity is drawing increasing interest, thus methods for such analyses are rapidly evolving. Here we describe a novel measure, “network homogeneity”, that allows for assessment of cohesiveness within a ...

Identifying Physical Interactions in Contact‐Based Robot Manipulation for Learning from Demonstration

Advanced Robotics Research, EarlyView.
Robots can learn manipulation tasks from human demonstrations. This work proposes a versatile method to identify the physical interactions that occur in a demonstration, such as sequences of different contacts and interactions with mechanical constraints.

Amnestic mild cognitive impairment individuals with dissimilar pathologic origins show common regional vulnerability in the default mode network

Alzheimer’s & Dementia: Diagnosis, Assessment & Disease Monitoring, 2018
Introduction Alzheimer's and Parkinson's disease (AD and PD) are distinct disorders but share similar biomarker profiles. The regions of the default mode network are implicated in these diseases and are associated with amnestic symptoms.

ChicGrasp: Imitation‐Learning‐Based Customized Dual‐Jaw Gripper Control for Manipulation of Delicate, Irregular Bio‐Products

Advanced Robotics Research, EarlyView.
Automated poultry processing lines still rely on humans to lift slippery, easily bruised carcasses onto a shackle conveyor. Deformability, anatomical variance, and hygiene rules make conventional suction and scripted motions unreliable. We present ChicGrasp, an end‐to‐end hardware‐software co‐designed imitation learning framework, to offer a ...

Ayahuasca and Default Mode Network

, 2015
To investigate how Ayahuasca interferes with the Default Mode Network (DMN) activity a fluency verbal task was used. Subjects underwent two fMRI sessions, before and 40 min after Ayahuasca intake. To evaluate DMN activity, a verbal fluency task, designed
