Ketamine produces rapid antidepressant and antidepressant-like effects in both humans and animal models. However, its therapeutic benefits are tempered by psychoactive side effects, such as hyperlocomotion associated with enhanced dopaminergic activity in the ventral tegmental area (VTA). We tested the therapeutic effect of cannabidiol (CBD) on locomotor activity after systemic (30 mg/kg) or...
Recent electrophysiological studies have suggested surges in electrical correlates of consciousness (i.e., elevated gamma power and connectivity) after cardiac arrest (CA). This study examines electrocorticogram (ECoG) activity and coherence of the dying brain during asphyxial CA. Male Wistar rats (n = 16) were induced with isoflurane anesthesia, which was washed out before asphyxial CA. Mean...
