Human short-term memory learning based on dynamic glutamate levels and oscillatory activities: concurrent metabolic and electrophysiological studies using event-related functional-MRS and EEG modalities

Author(s): Mohammadi H; Zargaran SJ; Khajehpour H; Adibi I; Rahimiforoushani A; Karimi S; Serej ND; Alam NR;

Short-term memory (STM) temporarily stores sensory information, critical for synaptic plasticity, memory, and learning, and is regulated by the glutamate-gated NMDA receptor. While the frontal and parieto-occipital cortices have been implicated in STM, the electrochemical dynamics of the right he ...

Validating MEG source imaging of resting state oscillatory patterns with an intracranial EEG atlas

Author(s): Afnan J; von Ellenrieder N; Lina JM; Pellegrino G; Arcara G; Cai Z; Hedrich T; Abdallah C; Khajehpour H; Frauscher B; Gotman J; Grova C;

Background: Magnetoencephalography (MEG) is a widely used non-invasive tool to estimate brain activity with high temporal resolution. However, due to the ill-posed nature of the MEG source imaging (MSI) problem, the ability of MSI to identify accurately underlying brain sources along the cortical ...

Effects of Transcranial Direct Current Stimulation on Attentional Bias to Methamphetamine Cues and Its Association With EEG-Derived Functional Brain Network Topology

Author(s): Khajehpour H; Parvaz MA; Kouti M; Hosseini Rafsanjani T; Ekhtiari H; Bakht S; Noroozi A; Makkiabadi B; Mahmoodi M;

Background: Although transcranial direct current stimulation (tDCS) has shown to potentially mitigate drug craving and attentional bias to drug-related stimuli, individual differences in such modulatory effects of tDCS are less understood. In this study, we aimed to investigate a source of the in ...
