The DLPFC is crucially involved in executive functioning, functions which are related to the course of addictive disorders. Non-invasive stimulation of the DLPFC may lead to changes in executive functioning. Currently an overview of effects of neuromodulation on these functions is lacking.

    Related ArticlesDissociable Roles Within the Social Brain for Self-Other Processing: A HD-tDCS Study. Cereb Cortex. 2018 Oct 01;: Authors: Martin AK, Huang J, Hunold A, Meinzer M Abstract Theories of right temporoparietal junction (rTPJ) function in social cognition include self-other distinction, self-inhibition, or embodied rotation, whereas the dorsomedial prefrontal cortex (dmPFC) is associated with integrating social information. However, no study has provided causal evidence for dissociable roles of the rTPJ and dmPFC in social cognition.

  • Nicotine modulates human brain plasticity via calcium-dependent mechanisms.
    Related ArticlesNicotine modulates human brain plasticity via calcium-dependent mechanisms. J Physiol. 2018 Sep 15;: Authors: Jessica G, Jerick B, Giorgi B, Min-Fang K, Walter P, Michael N Abstract KEY POINT: Nicotine modulates cognition and memory function by targeting the nicotinic acetylcholine receptor and releasing different transmitter systems postsynaptically. With both nicotine-generated mechanisms, calcium influx and calcium permeability can be regulated, which is a key requirement for the induction of long-term potentiation, the physiological basis of learning and memory function. We try to unmask the underlying mechanism of nicotinic effects on anodal tDCS-induced LTP-like plasticity based on the hypothesis of calcium-dependency. ... read more
