Separating the brain regions involved in recollection and familiarity in recognition memory [PDF]

, 2005
The neural substrates of recognition memory retrieval were examined in a functional magnetic resonance imaging study designed to separate activity related to recollection from that related to continuous variations in familiarity.

Identification of a Second‐Hit Brain Somatic DEPDC5 Variant Supports Causality of a DEPDC5 Germline Variant of Uncertain Significance. Time for a Classification Update?

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Germline variants in DEPDC5 are a cause of familial focal epilepsy with variable foci. Affected individuals may have focal cortical dysplasia if a second brain somatic variant occurs. As access to brain tissue is limited, the second somatic hit in the brain is usually presumed if a clear pathogenic germline variant is present. Here, we present

Transcranial direct current stimulation over the right parietal cortex improves the depressive disorder: A preliminary study

Brain and Behavior
Objective The right posterior parietal cortex is the core brain region of emotional processing and executive control network in the human brain, and the function of the right posterior parietal cortex is decreased in patients with major depressive ...

Flexible adjustment of the effective connectivity between the fronto-parietal and visual regions supports cognitive flexibility

NeuroImage, 2020
Evidence indicates the significance of the fronto-parietal regions and inertia sensory processing from previous trials in cognitive flexibility. However, how flexible cognitive performance is achieved by causal interactions between cortical regions ...

Planning Movements in Visual and Physical Space in Monkey Posterior Parietal Cortex.

Cerebral Cortex, 2015
Neurons in the posterior parietal cortex respond selectively for spatial parameters of planned goal-directed movements. Yet, it is still unclear which aspects of the movement the neurons encode: the spatial parameters of the upcoming physical movement ...

Mesoscale functional architecture in medial posterior parietal cortex

, 2023
The posterior parietal cortex (PPC) in mice has various functions including multisensory integration, vision-guided behaviors, working memory, and posture control. However, an integrated understanding of these functions and their cortical localizations in and around the PPC and higher visual areas (HVAs), has not been completely elucidated.

Cerebral Small Vessel Disease in Older Adults With Olfactory Dysfunction

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Poor vascular health has been associated with age‐related declines in sensory functions, including olfaction. The current study was designed to test the hypothesis that cerebral small vessel disease underlies poor olfactory function due to structural declines in brain regions that support olfaction.

Altered resting-state connectivity in subjects at ultra-high risk for psychosis: an fMRI study

Behavioral and Brain Functions, 2010
Background Individuals at ultra-high risk (UHR) for psychosis have self-disturbances and deficits in social cognition and functioning. Midline default network areas, including the medial prefrontal cortex and posterior cingulate cortex, are implicated in

Early error detection predicted by reduced pre-response control process: an ERP topographic mapping study [PDF]

, 2010
Advanced ERP topographic mapping techniques were used to study error monitoring functions in human adult participants, and test whether proactive attentional effects during the pre-response time period could later influence early error detection ...
