Implicit memory

…its effects on distinct types of memory. Here, we investigated the effects of an antidepressant dose (10 mg/kg) of ketamine on encoding, retrieval, and modulation processes in an implicit and an explicit memory task in adult male Wistar rats (n = 60). Ketamine (IP) was administered 30 minutes either before the acquisition, retrieval, or extinction phase of auditory fear conditioning (implicit task). Similarly, different groups of animals rec

Learning a word, involves mapping low-level perceptual representations of world-referents to high-level semantic representations. It is widely held that conscious access to the visual world-referents is needed to learn the meaning of words. The aim of this study was to use fMRI-based decoded neurofeedback (DecNef) to incept a perceptual meaning into brain representations of meaningless symbols, and do so without participant’s awareness, hence by-passing the explicit mapping between words and perceptual referents in brain regions involved in semantic representation. Accordingly, we developed
