    Ventromedial prefrontal cortex stimulation enhances memory and hippocampal neurogenesis in the middle-aged rats

    Albert Liu et al.
    High-frequency stimulation of the ventromedial prefrontal cortex, which enhances memory and hippocampal neurogenesis, is a novel target for treatment of dementia-related diseases.

    Odor-evoked category reactivation in human ventromedial prefrontal cortex during sleep promotes memory consolidation

    Laura K Shanahan et al.
    Odor cues in sleep evoke content-specific signatures of neural reactivation in visual and prefrontal brain areas that predict subsequent memory performance in the wake state.

    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.

    Human VMPFC encodes early signatures of confidence in perceptual decisions

    Sabina Gherman, Marios G. Philiastides
    Simultaneous EEG-fMRI reveals neural representations of decision confidence unfolding prior to explicit perceptual choices, in a region of the ventromedial prefrontal cortex typically linked to reward processing and value-based decisions.

    Neural and computational processes underlying dynamic changes in self-esteem

    Geert-Jan Will et al.
    Self-esteem, the value that people ascribe to the self, is represented in the ventromedial prefrontal cortex and dynamically updated when people learn how others value them.

    How prior preferences determine decision-making frames and biases in the human brain

    Alizée Lopez-Persem et al.
    Model-based analyses of choice behavior and fMRI activity revealed that prior preferences generate default policies, which frame the decision value signal encoded in the vmPFC, and shift vmPFC pre-choice activity so as to induce a decision bias toward default options.

    Autism: Balancing excitation and inhibition in the autistic brain

    Charlotte M Pretzsch, Dorothea L Floris
    A metric called the Hurst exponent could be a useful biomarker for studies exploring brain differences between men and women with autism spectrum disorder.

    Preparation for upcoming attentional states in the hippocampus and medial prefrontal cortex

    Eren Günseli, Mariam Aly
    Memory guides attention by enabling preparation for upcoming states in the hippocampus and medial prefrontal cortex.

    Distinct neural contributions to metacognition for detecting, but not discriminating visual stimuli

    Matan Mazor et al.
    Combining psychophysics and functional MRI reveals a qualitative asymmetry in neural engagement when reflecting on whether a stimulus is seen (detection) compared to reflecting on what a stimulus is (discrimination).
