Upper Lumbar Pedicle Screw Insertion Using Three-Dimensional Fluoroscopy Navigation:Assessment of Clinical Accuracy [PDF]

open access: yes, 2010
We used a navigation system to insert 128 pedicle screws into 69 vertebrae (L1 to L3) of 49 consecutive patients. We assessed the pedicle isthmic width and the permission angle for pedicle screw insertion. The permission angle is the angle defined by the

A connectional hub in the rostral anterior cingulate cortex links areas of emotion and cognitive control

open access: yeseLife, 2019
We investigated afferent inputs from all areas in the frontal cortex (FC) to different subregions in the rostral anterior cingulate cortex (rACC). Using retrograde tracing in macaque monkeys, we quantified projection strength by counting retrogradely ...

Cingulum bundle connectivity considering the double-layered cingulate cortex using diffusion-weighted MRI

open access: yesNeuroImage: Reports, 2021
The cingulum bundle (CB) is a fasciculus in the white matter surrounded by the cingulate cortex, which is generally subdivided into the anterior, middle, and posterior parts based on their function and cytology.

The Dopaminergic Midbrain Encodes the Expected Certainty about Desired Outcomes [PDF]

open access: yes, 2014
Dopamine plays a key role in learning; however, its exact function in decision making and choice remains unclear. Recently, we proposed a generic model based on active (Bayesian) inference wherein dopamine encodes the precision of beliefs about optimal ...

How Does the Cerebral Cortex Work? Developement, Learning, Attention, and 3D Vision by Laminar Circuits of Visual Cortex [PDF]

open access: yes, 2003
A key goal of behavioral and cognitive neuroscience is to link brain mechanisms to behavioral functions. The present article describes recent progress towards explaining how the visual cortex sees.

What Does the Frontopolar Cortex Contribute to Goal-Directed Cognition and Action?

open access: yesJournal of Neuroscience, 2022
Understanding the unique functions of different subregions of primate prefrontal cortex has been a longstanding goal in cognitive neuroscience. Yet, the anatomy and function of one of its largest subregions (the frontopolar cortex) remain enigmatic and ...

Navigating the complex path between the oxytocin receptor gene (OXTR) and cooperation: an endophenotype approach

open access: yesFrontiers in Human Neuroscience, 2013
Although cooperation represents a core facet of human social behavior there exists considerable variability across people in terms of the tendency to cooperate.

Parametric Representation of Tactile Numerosity in Working Memory [PDF]

open access: yes, 2020
Estimated numerosity perception is processed in an approximate number system (ANS) that resembles the perception of a continuous magnitude. The ANS consists of a right lateralized frontoparietal network comprising the lateral prefrontal cortex (LPFC) and

Localizing ECoG electrodes on the cortical anatomy without post-implantation imaging

open access: yesNeuroImage: Clinical, 2014
Introduction: Electrocorticographic (ECoG) grids are placed subdurally on the cortex in people undergoing cortical resection to delineate eloquent cortex. ECoG signals have high spatial and temporal resolution and thus can be valuable for neuroscientific
