A Novel Insular/Orbital-Prelimbic Circuit That Prevents Persistent Avoidance in a Rodent Model of Compulsive Behavior.
Publication Type: Academic Journal
Source(s): Biological psychiatry [Biol Psychiatry] 2023 Jun 01; Vol. 93 (11), pp. 1000-1009. Date of Electronic Publication: 2022 Feb 19.
Abstract: Background: A common symptom of obsessive-compulsive disorder is the persistent avoidance of cues incorrectly associated with negative outcomes. This maladaptation becomes increasingly evident as subjects fail to respond to extinction-based treatments ...
Cortical activity emerges in region-specific patterns during early brain development.
Publication Type: Academic Journal
Source(s): Proceedings of the National Academy of Sciences of the United States of America [Proc Natl Acad Sci U S A] 2023 May 30; Vol. 120 (22), pp. e2208654120. Date of Electronic Publication: 2023 May 22.
Abstract: The development of precise neural circuits in the brain requires spontaneous patterns of neural activity prior to functional maturation. In the rodent cerebral cortex, patchwork and wave patterns of activity develop in somatosensory and visual regions,...
Identification of Novel BDNF-Specific Corticostriatal Circuitries.
Publication Type: Academic Journal
Source(s): ENeuro [eNeuro] 2023 May 16; Vol. 10 (5). Date of Electronic Publication: 2023 May 16 (Print Publication: 2023).
Abstract: Brain-derived neurotrophic factor (BDNF) is released from axon terminals originating in the cerebral cortex onto striatal neurons. Here, we characterized BDNF neurons in the corticostriatal circuitry. First, we used BDNF -Cre and Ribotag transgenic mou...
The prelimbic cortex but not the anterior cingulate cortex plays an important role in social recognition and social investigation in mice.
Publication Type: Academic Journal
Source(s): PloS one [PLoS One] 2023 Apr 21; Vol. 18 (4), pp. e0284666. Date of Electronic Publication: 2023 Apr 21 (Print Publication: 2023).
Abstract: The prefrontal cortex (PFC) has been implicated in social cognitive functions and emotional behaviors in rodents. Each subregion (prelimbic cortex, PL; infralimbic cortex; and anterior cingulate cortex, ACC) of the PFC appears to play a different role ...
Conduct problems are associated with accelerated thinning of emotion-related cortical regions in a community-based sample of adolescents.
Publication Type: Academic Journal
Source(s): Psychiatry research. Neuroimaging [Psychiatry Res Neuroimaging] 2023 Apr; Vol. 330, pp. 111614. Date of Electronic Publication: 2023 Feb 15.
Abstract: Few studies have examined the association between conduct problems and cerebral cortical development. Herein, we characterize the association between age-related brain change and conduct problems in a large longitudinal, community-based sample of adole...
Hippocampal and motor regions contribute to memory benefits after enacted encoding: cross-sectional and longitudinal evidence.
Publication Type: Academic Journal
Source(s): Cerebral cortex (New York, N.Y. : 1991) [Cereb Cortex] 2023 Mar 10; Vol. 33 (6), pp. 3080-3097.
Abstract: The neurobiological underpinnings of action-related episodic memory and how enactment contributes to efficient memory encoding are not well understood. We examine whether individual differences in level (n = 338) and 5-year change (n = 248) in the abil...
Mapping frontoinsular cortex from diffusion microstructure.
Publication Type: Academic Journal
Source(s): Cerebral cortex (New York, N.Y. : 1991) [Cereb Cortex] 2023 Mar 10; Vol. 33 (6), pp. 2715-2733.
Abstract: We developed a novel method for mapping the location, surface area, thickness, and volume of frontoinsular cortex (FI) using structural and diffusion magnetic resonance imaging. FI lies in the ventral part of anterior insular cortex and is characterize...
Optimal blocking of the cerebral cortex for cytoarchitectonic examination: a neuronavigation-based approach.
Publication Type: Academic Journal
Source(s): Cerebral cortex (New York, N.Y. : 1991) [Cereb Cortex] 2023 Mar 10; Vol. 33 (6), pp. 2704-2714.
Abstract: Certain sulci of the human cerebral cortex hold consistent relationships to cytoarchitectonic areas (e.g. the primary motor cortical area 4 and the somatosensory cortical area 3 occupy the anterior and posterior banks of the central sulcus, respectivel...
Highly synchronized cortical circuit dynamics mediate spontaneous pain in mice.
Publication Type: Academic Journal
Source(s): The Journal of clinical investigation [J Clin Invest] 2023 Mar 01; Vol. 133 (5). Date of Electronic Publication: 2023 Mar 01.
Abstract: Cortical neural dynamics mediate information processing for the cerebral cortex, which is implicated in fundamental biological processes such as vision and olfaction, in addition to neurological and psychiatric diseases. Spontaneous pain is a key featu...
How distinct functional insular subdivisions mediate interacting neurocognitive systems.
Publication Type: Academic Journal
Source(s): Cerebral cortex (New York, N.Y. : 1991) [Cereb Cortex] 2023 Feb 20; Vol. 33 (5), pp. 1739-1751.
Abstract: Recent neurocognitive models propose that the insula serves as a hub of interoceptive awareness system, modulating 2 interplaying neurocognitive systems: The posterior insula (PI) receives and integrates various interoceptive signals; these signals are...
