Acetylcholine dynamics in the retrosplenial cortex during spatial uncertainty
… divided into expected and unexpected forms. The retrosplenial cortex (RSC) is a hub for spatial navigation and the default mode network, integrating egocentric and allocentric inputs, contextual information, and multiple spatial hypotheses. This positions the RSC as a key region for investigating …

Mechanism of transcranial focused ultrasound regulating the neuronal activity of the retrosplenial cortex
… activity in the pain-related brain region, retrosplenial cortex (RSC). Moreover, tFUS significantly increased paw withdrawal threshold (PWT) and prolonged thermal withdrawal latency (TWL) both in naïve and neuropathic mice. tFUS also significantly increased mRNA and protein expression levels …

Cross-species comparisons of the retrosplenial cortex in primates: Through time and neuropil space
… or planning, among non-human species. The retrosplenial cortex (Brodmann’s areas 29 and 30) plays a critical role in episodic memory, which is vital for MTT. Because MTT appears to be a uniquely human capacity, this region is of major interest for evolutionary studies. However, comparative …

Granular retrosplenial cortex layer 2/3 generates high frequency oscillation events coupled with hippocampal sharp wave-ripples and Str. LM high gamma
… cortical synaptic reorganization. The granular retrosplenial cortex (gRSC) is an associational area that exhibits high frequency oscillations (HFOs) during both hippocampal theta and SPW-Rs, and is potentially a period when the gRSC interprets incoming content from the hippocampus during …

Separating Component Signals of Episodic Simulation Using a Catch Trial Design
… regions in bilateral parahippocampal and right retrosplenial cortex show increased activity for the simulation of past events relative to the simulation of future events. This finding suggests that multiple, temporally overlapping processes exist in regions involved in episodic simulation, and …

Social cognitive impairments Arc gene implication and ketamine as a potential treatment [Deficits socio-cognitivi Coinvolgimento del gene Arc e ketamina come potenziale trattamento]
… di ketamina, sia intraperitoneale sia nella retrosplenial cortex (RSC), porta al recupero completo di queste capacità fino a sette giorni dopo la somministrazione. I nostri risultati indicano che il gene Arc è specificamente coinvolto nei meccanismi sottostanti il riconoscimento delle …

Hippocampal Output to the Septum Regulates Locomotion and Exploration
… On the other hand, activation of a subset of retrosplenial cortex-specific projecting DH INs or the entorhinal cortex-projecting DH neurons did not change animal locomotion. For the clinical application, targeting the DH-MSc inhibitory pathway can help us to determine the neuronal mechanisms …

Neural correlates of temporal context retrieval
… associated with the hippocampus, parahippocampal cortex, ventromedial prefrontal cortex, retrosplenial cortex, and posterior cingulate, which are consistent with the retrieval of non-temporal context in episodic memory. The results also suggest that temporal context retrieval could rely on …

Molecular regulation of vasopressin receptor among (mostly) monogamous prairie voles
… of the vasopressin receptor 1a (V1aR) in the retrosplenial cortex (RSC), a brain region implicated in spatial memory. We find that variation in RSC-V1aR and associated behaviors are predicted by two alternative avpr1a alleles. These “HI” and “LO” alleles are defined by four linked single …

Spatial-memory control of defensive actions
… in candidate areas, which showed that the retrosplenial cortex (RSC) plays a critical role in escape accuracy. Furthermore, channelrhodopsin-2-assisted connectivity studies showed a functional connection between RSC and SC, and chemogenetic inactivation of this projection impaired accurate …

Cortico-thalamic interactions for head direction coding
… how HD is modulated are largely unknown. Retrosplenial cortex (RSC) is a key region for spatial cognition and exhibits dense interconnection with visual and motor areas, the hippocampal formation, and diverse thalamic nuclei. Of these, the anterodorsal thalamus (ADn) is the major avenue by …

Behavioral Strategies and Neural Mechanisms of Dynamic Foraging
… corresponding to the frontal, motor, visual and retrosplenial regions that have different dynamic representations of rewards and errors. Dissecting single-neuron responses in these candidate regions with three-photon imaging across cortical depths revealed specialized processing of reward-related …

Age related memory loss and the role of the ubiquitin proteasome system
… protein targeting in the hippocampus and retrosplenial cortex of male and female rats across their lifespan. In terms of targeted protein degradation in the hippocampus, altered protein degradation targets were involved in transcription, astrocyte structure, G-protein, and interferon …
