The neurological underpinnings of cluttering: Some initial findings [PDF]

open access: yes, 2015
Background Cluttering is a fluency disorder characterised by overly rapid or jerky speech patterns that compromise intelligibility. The neural correlates of cluttering are unknown but theoretical accounts implicate the basal ganglia and medial ...

Memory and Resting‐State Connectivity in Acute Transient Global Amnesia: A Case–Control fMRI Study

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background and Objectives Transient global amnesia (TGA) is a striking model of isolated amnesia. While hippocampal lesions are well described, the network‐level mechanisms and the precise neuropsychological profile remain debated. Our objective was thus to characterize functional and neuropsychological correlates of acute TGA and their ...

Effects of anterior cingulate cortex lesions on a continuous performance task for mice

open access: yesBrain and Neuroscience Advances, 2018
Background: Important tools in the study of prefrontal cortical -dependent executive functions are cross-species behavioural tasks with translational validity. A widely used test of executive function and attention in humans is the continuous performance

Abnormal Spontaneous Neural Activity in Obsessive-Compulsive Disorder: A Resting-State Functional Magnetic Resonance Imaging Study. [PDF]

open access: yesPLoS ONE, 2013
Neuroimaging studies of obsessive-compulsive disorder have found abnormalities in orbitofronto-striato-thalamic circuitry, including the orbitofrontal cortex, anterior cingulate cortex, caudate, and thalamus, but few studies have explored abnormal ...

Spatial and Volumetric Characteristics of Glioblastoma: Associations With Clinical Presentation and Survival

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective We aim to comprehensively analyze how regional tumor and edema characteristics are associated with clinical presentations and survival outcomes in a large cohort of glioblastoma patients. Methods Patients with IDH‐wildtype glioblastoma who received brain MRI from 2010 to 2023 were included.

Top-down descending facilitation of spinal sensory excitatory transmission from the anterior cingulate cortex

open access: yesNature Communications, 2018
Spinal sensory transmission is under descending biphasic modulation, and descending facilitation is believed to contribute to chronic pain. Descending modulation from the brainstem rostral ventromedial medulla (RVM) has been the most studied, whereas ...

Expectations, gains, and losses in the anterior cingulate cortex [PDF]

open access: yesCognitive, Affective, & Behavioral Neuroscience, 2007
The anterior cingulate cortex (ACC) participates in evaluating actions and outcomes. Little is known on how action-reward values are processed in ACC and if the context in which actions are performed influences this processing. In the present article, we report ACC unit activity of monkeys performing two tasks.

Atypical functional connectivity between the anterior cingulate cortex and other brain regions in a rat model of recurrent headache

open access: yesMolecular Pain, 2019
We explored the atypical functional connectivity between the anterior cingulate cortex and other brain areas in rats subjected to repeated meningeal nociception.

Silent synapses in pain-related anterior cingulate cortex

open access: yesMolecular Pain, 2023
Synaptic plasticity such as Long-term potentiation (LTP) is a key mechanism for learning in central synapses including the cortex. There are two least two major forms of LTPs: presynaptic LTP and postsynaptic LTP.

Effects of focal frontal lesions on response inhibition [PDF]

open access: yes, 2007
This study examined the performance of 38 normal subjects and 43 patients with focal lesions of the frontal lobes on a simple go-nogo task where the probability of the nogo stimulus was either 75% or 25%.
