Frontal and anterior cingulate activation during overt verbal fluency in patients with first episode psychosis Ativação frontal e do cíngulo anterior durante tarefa de fluência verbal em pacientes em primeiro episódio psicótico

Brazilian Journal of Psychiatry, 2005
OBJECTIVE: Functional neuroimaging studies using phonological verbal fluency tasks allow the assessment of neural circuits relevant to the neuropsychology of psychosis.

Neuropsychology of reinforcement processes in the rat [PDF]

, 2011
This thesis investigated the role played by regions of the prefrontal cortex and ventral striatum in the control of rats’ behaviour by Pavlovian conditioned stimuli, and in their capacity to choose delayed reinforcement.

Arterial Spin‐Labeling MRI at the Cortical‐CSF Interface: A Novel Biomarker in Alzheimer Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background/Objective Arterial spin‐labeling (ASL) MRI can measure perfusion signal adjacent to CSF spaces and may provide information regarding CSF‐adjacent water transport physiology. We developed an automated pipeline to extract cortical‐CSF interface (IF) perfusion for comparison between Alzheimer disease (AD) and cognitively normal ...

When planning fails: Individual differences and error-related brain activity in problem solving. [PDF]

, 2004
The neuronal processes underlying correct and erroneous problem solving were studied in strong and weak problem-solvers using functional magnetic resonance imaging (fMRI).

Posterior Disconnection Syndrome in Early‐Stage Adult‐Onset Cerebral Adrenoleukodystrophy

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Adult‐onset cerebral adrenoleukodystrophy is potentially treatable but often difficult to recognize before advanced cerebral involvement. Herein, we describe three men with early‐stage disease who initially presented with subtle visual complaints rather than subcortical dementia. Targeted neuropsychological testing revealed higher‐order visual

Decreased NOS1 Expression in the Anterior Cingulate Cortex in Depression [PDF]

Cerebral Cortex, 2012
Decreased function of the anterior cingulate cortex (ACC) is crucially involved in the pathogenesis of depression. A key role of nitric oxide (NO) has also been proposed. We aimed to determine the NO content in the cerebrospinal fluid (CSF) and the expression of NO synthase (NOS) isoforms, that is, NOS1, NOS2, and NOS3 in the ACC in depression.

The Mind From Within: Visceral Roots of Human Cognition

Advanced Science, EarlyView.
The physiological activity of visceral organs, such as the heart, the lungs, and the gut, is surprisingly linked to many sophisticated mental operations, such as remembering the past, being aware of ourselves, making choices, and forging social bonds.

Anterior cingulate cortex and its input to the basolateral amygdala control innate fear response

Nature Communications, 2018
Prefrontal brain areas are implicated in the control of fear behavior. However, how prefrontal circuits control fear response to innate threat is poorly understood.

Reward Encoding in the Monkey Anterior Cingulate Cortex

Cerebral Cortex, 2005
The anterior cingulate cortex (ACC) is known to play a crucial role in the fast adaptations of behavior based on immediate reward values. What is less certain is whether the ACC is also involved in long-term adaptations to situations with uncertain outcomes.

Anticipation of conflict monitoring in the anterior cingulate cortex and the prefrontal cortex [PDF]

Proceedings of the National Academy of Sciences, 2007
The anterior cingulate cortex (ACC) has been suggested as a monitoring center that is responsible for online detection of response conflicts. In this view, the conflict signal detected by the ACC is transmitted to other brain regions, such as the dorsal part of the lateral prefrontal cortex (lPFC), to increase the level of cognitive control.
