Choice overload reduces neural signatures of choice set value in dorsal striatum and anterior cingulate cortex

Elena Reutskaja, Axel Lindner, Rosemarie Nagel, Richard A. Andersen, Colin F. Camerer
2018 Nature Human Behaviour  
Activity in the striatum and anterior cingulate reflects choice set value and can serve as neural indicator of choice overload.  ...  When choosing from sets of 6, 12 or 24 items, functional magnetic resonance imaging activity in the striatum and anterior cingulate cortex resembled an inverted U-shaped function of choice set size.  ...  Saccades were detected using an absolute velocity threshold (20deg/s), while blinks were identified as gaps in the eye position records due to lid closure.  ...

Cortical Mechanisms Underlying the Organization of Goal-Directed Actions and Mirror Neuron-Based Action Understanding

Giacomo Rizzolatti, Luigi Cattaneo, Maddalena Fabbri-Destro, Stefano Rozzi
2014 Physiological Reviews  
Motor system is not considered anymore just a "producer" of movements, as it was in the past, but a system crucially involved in cognitive functions.  ...  This is the consequence not only of an increase in the amount of data on this system but especially of a paradigm shift in our conceptualization of it.  ...  and by the face/head movements.  ...

2018 Encyclopedia of Ophthalmology  
In some instances attempting eye opening can result in a vigorous contraction of the frontalis muscle, backward thrusting of the head, and delay in lid closure.  ...  Mechanical opening of the lids or use of an alleviating maneuver (e.g., sensory trick) can stop or reduce the spasm and allow the lids to open the coordination of eyelid movement, pursuit eye movements  ...  Etiology A-AION specifically affects the anterior optic nerve head due to ischemia from the posterior ciliary arteries.  ...

Making translation work: Harmonizing cross-species methodology in the behavioural neuroscience of Pavlovian fear conditioning

Jan Haaker, Stephen Maren, Marta Andreatta, Christian J. Merz, Jan Richter, S. Helene Richter, Shira Meir Drexler, Maren D. Lange, Kay Jüngling, Frauke Nees, Thomas Seidenbecher, Miquel A. Fullana (+2 others)
2019 Neuroscience and Biobehavioral Reviews  
Translational neuroscience bridges insights from specific mechanisms in rodents to complex functions in humans and is key to advance our general understanding of central nervous function.  ...  Hitherto, evidence for (and critique of) these cross-species comparisons in fear conditioning research was based on theoretical viewpoints.  ...  Startle responses that are elicited for example by a sudden, loud noise (so called startle probe) include the contraction of facial, neck and skeletal muscles, resulting in eye-lid-closure, and a disruption  ...

2009 Canadian Journal of Neurological Sciences  
Possible mechanisms will be presented and the use of head thrusts and eye blinks to initiate saccades will be explained in light of recent fMRI data.  ...  : Misdiagnosis of PNES is common as they may mimic epileptic seizures and occur in patients with epilepsy.  ...  Hogan (Ottawa)* Background: A key problem in employing exploratory analysis methods to fMRI is that after the voxels have been clustered into groups, the significance of the clusters remains unknown.  ...

2012 Basal Ganglia  
This study aims to assess, in a noninterventional epidemiological setting, the incidence and severity of fatigue in PD patients and its correlation with PD severity.  ...  Results: 402 patients (mean age: 66.9 years; mean disease duration: 7.5 years) were enrolled in 27 PD centers in Italy. 33.8% of them showed fatigue (PFS-16 score AE 3.3 points). Logistic regression  ...  Resting-state fMRI revealed an increased signal in the head of the caudate nucleus bilaterally.  ...
