DOI: 10.1016/j.bbr.2019.112347
Abstract: Metaplastic effects of the NMDARs blocker ketamine at the neural and behavioural levels have been described as potential mechanisms underlying the beneficial effects in treatment-resistant depression. However, ketamine effects on addictive behaviours are still unexplored.… read more here.

DOI: 10.1016/j.cub.2020.09.074
Abstract: Summary Novelty facilitates memory formation and is detected by both the dorsal and ventral hippocampus. Although dentate granule cells (GCs) in the dorsal hippocampus are known to mediate the formation of novelty-induced contextual memories, the… read more here.

DOI: 10.1038/s42003-020-0862-z
Abstract: Findings have shown that anterior insular cortex (aIC) lesions disrupt the maintenance of drug addiction, while imaging studies suggest that connections between amygdala and aIC participate in drug-seeking. However, the role of the BLA → aIC pathway… read more here.

DOI: 10.1515/biol-2020-0006
Abstract: Abstract Background The opioid Morphine is known to affect neurogenesis in the hippocampus. Evidence has shown that several microRNAs modulate morphine-induced neurogenesis, and hence morphine-induced contextual memory. This complex network has yet to be elucidated.… read more here.

DOI: 10.1523/eneuro.0253-17.2017
Abstract: Abstract Early life adversity is a well-known risk factor for behavioral dysfunction later in life, including the formation of contextual memory; it is also (transiently) accompanied by hyperactivity of the stress system. We tested whether… read more here.

DOI: 10.3389/fphar.2018.00607
Abstract: HIGHLIGHTS The injection of p-chlorophenylalanine, specific blocker of 5-HT synthesis 3 days before reminder with anisomycin administration prevented forgetting. It is known that the reminder cause reactivation of the long-term memory and it leads to… read more here.
