Prepulse inhibition predicts spatial working memory performance in the inbred Roman high- and low-avoidance rats and in genetically heterogeneous NIH-HS rats: relevance for studying pre-attentive and cognitive anomalies in schizophrenia.

Ignasi Oliveras, +8 more
- 18 Aug 2015 - 
TL;DR: Using genetically-selected and genetically heterogeneous rats, the present study shows, for the first time, that PPI is a positive predictor of performance in a spatial working memory task.
Journal ArticleDOI

Schizophrenia-like reduced sensorimotor gating in intact inbred and outbred rats is associated with decreased medial prefrontal cortex activity and volume.

Carles Tapias-Espinosa, +8 more
- 16 Apr 2019 - 
TL;DR: The results support the notion that sensorimotor gating is modulated by forebrain structures and highlight the importance of the mPFC in its regulation and suggest that, apart from a hypoactive and smaller mP FC, a hyperactive NAc and smaller HPC may underlie reduced PPI levels.
Journal ArticleDOI

Neonatal handling enduringly decreases anxiety and stress responses and reduces hippocampus and amygdala volume in a genetic model of differential anxiety: Behavioral-volumetric associations in the Roman rat strains.

Cristóbal Río-Álamos, +10 more
- 01 Feb 2017 - 
TL;DR: Results showed untreated RLA rats showed higher anxiety and post-stress hormone responses, as well as greater hippocampus and amygdala volumes than untreated RHA rats, and there were positive associations between anxiety and PPI and hippocampus/amygdala volumes.
Journal ArticleDOI

Differential expression of synaptic markers regulated during neurodevelopment in a rat model of schizophrenia-like behavior

Betina Elfving, +8 more
- 20 Dec 2019 - 
TL;DR: It is found that SYP, GRIN2B, NRG1, HOMER1, DRD1 and BDNF expression is upregulated in PFC during childhood and adolescence, suggesting a more immature neurobiological endophenotype in the RHA-I strain.
Journal ArticleDOI

Volumetric brain differences between the Roman rat strains: Neonatal handling effects, sensorimotor gating and working memory.

Cristóbal Río-Álamos, +11 more
- 01 Apr 2019 - 
TL;DR: It was found that, compared with their RLA counterparts, RHA rats show increased exploration of the novel object in the NOE test, lowered anxiety in the ZM and impaired PPI, whereas RLAs display better spatial reference learning and memory and better cognitive flexibility in a reversal task.
