    Partial loss of CFIm25 causes learning deficits and aberrant neuronal alternative polyadenylation

    Callison E Alcott et al.
    Partial reduction of CFIm25 protein levels leads to misregulated alternative polyadenylation in neurons and learning deficits.

    Cerebellar associative sensory learning defects in five mouse autism models

    Alexander D Kloth et al.
    Five mouse models of autism show deficits in delay eyeblink conditioning, a form of split-second sensory learning that involves the cerebellum, a frequent site of disruption in autistic brains.

    Functional heterogeneity within the rodent lateral orbitofrontal cortex dissociates outcome devaluation and reversal learning deficits

    Marios C Panayi, Simon Killcross
    The rodent orbitofrontal cortex makes functionally distinct contributions to flexible behavioural control, even within a single putative orbitofrontal subregion, which has important implications for establishing homology between rodent and primate orbitofrontal cortex.

    Deficit of mitogen-activated protein kinase phosphatase 1 (DUSP1) accelerates progressive hearing loss

    Adelaida M Celaya et al.
    Mitogen-activated protein kinase phosphatase 1 (DUSP1) deficiency causes early redox imbalance and increased inflammatory response in the cochlea, leading to cell loss and progressive neurosensory hearing loss.

    CCR5 is a suppressor for cortical plasticity and hippocampal learning and memory

    Miou Zhou et al.
    Repression of the G protein-coupled chemokine receptor CCR5 enhances MAPK/CREB signaling, long-term potentiation, somatosensory cortical plasticity, and learning and memory, while CCR5 over-activation by viral proteins may contribute to HIV-associated cognitive deficits.

    Attenuation of dopamine-modulated prefrontal value signals underlies probabilistic reward learning deficits in old age

    Lieke de Boer et al.
    Attenuated anticipatory activity in ventromedial prefrontal cortex is modulated by dopamine D1 receptor density in nucleus accumbens, and accounts for impaired probabilistic reward learning in older adults.

    Dysregulation of sonic hedgehog signaling causes hearing loss in ciliopathy mouse models

    Kyeong-Hye Moon et al.
    Developmental defects of the cochlea caused by dysregulation of sonic hedgehog signaling are the potential etiology for hearing loss in a group of ciliopathies with defective ciliogenesis.

    5'-UTR SNP of FGF13 causes translational defect and intellectual disability

    Xingyu Pan et al.
    A 5'-UTR SNP of FGF13 impairs PTBP2 interacting with FGF13 mRNA, leading to reduced FGF13 translation and deficits in brain development and cognitive functions.

    Synaptic plasticity and cognitive function are disrupted in the absence of Lrp4

    Andrea M Gomez et al.
    Lrp4 mutant mice display profound deficits in cognitive tasks that assess learning and memory with disruptions in the subcellular organization of synaptic inputs and synaptic plasticity in the hippocampus.

    Impaired voice processing in reward and salience circuits predicts social communication in children with autism

    Daniel Arthur Abrams et al.
    Children with autism often 'tune out' the voices in their environment and new results show that impaired processing of voices in the brain's reward system may underlie this social behavior.
