Summary: Psychoactive drugs can affect learning and emotional processes, which may impact their recreational and medical use. Recent research has shown that these drugs can have varying effects on different stages of processing emotional episodic memories, including encoding, consolidation, and retrieval. Drugs administered before encoding can impair, enhance, or both impair and enhance emotionally negative and positive memories compared to neutral memories. GABAA sedatives administered during consolidation may enhance emotional memories, but this selectivity may decrease or reverse as the delay between encoding and retrieval increases. Finally, retrieving memories under the influence of certain drugs can distort memory, with a potentially stronger effect on emotional (especially positive) memories. This article reviews these effects, proposes neural mechanisms, discusses methodological considerations for future studies, and speculates on how drug effects on emotional episodic memory may contribute to drug use and abuse.

Summary: This study examined the impact of emotion on memory retention and found that it is modulated by encoding type and retention interval. The effects of emotion on memory differ depending on the type of encoding and the duration of retention.

Summary: This study demonstrates that sounds have an influence on the perception and emotional responses of both emotional and non-emotional foods. Pleasant and unpleasant sounds significantly impact the perceived flavor, affective states, and emotional responses of chocolate milkshake and vegetable ice cream.

Summary: Coherent modulation imaging (CMI) improves the convergence performance of coherent diffraction imaging by introducing a pre-characterized wave modulator, but traditional algorithms suffer from low SNR. This study proposes a revised CMI algorithm based on beam splitting encoding and averaging, demonstrating fast convergence speed and high SNR in simulations and experiments.

Summary: The amygdala in primates plays a crucial role in processing emotional valence and intensity of visual stimuli, encoding information about both emotional valence and intensity to guide the avoidance of dangerous stimuli and ensure survival.

Summary: This study identifies brain states using scalp EEG from male and female human subjects and shows the extent to which temporal overlap promotes interference and induces retrieval. Greater temporal overlap leads to impaired memory for the past event selectively when the top-down goal is to encode the present event. Additionally, greater temporal overlap leads to automatic retrieval of a past event, independent of top-down goals. These findings provide insight into the role of temporal overlap on interference and memory formation.

Summary: Temporary inactivation of the retrosplenial cortex impaired retrieval of remotely conditioned auditory cue, but not recently conditioned one. Inactivation during encoding had no impact on later retrieval testing for both remotely and recently conditioned auditory cue. This suggests the RSC plays a role in retrieval, but not encoding, of remotely acquired auditory fear conditioning.

Summary: During developmental critical periods, early-life stress induces cognitive deficits and alters neural circuitry in regions underlying learning, memory, and attention. Sensory processing may also be vulnerable to early-life stress as mechanisms underlying critical period plasticity are shared by sensory cortices. In this study using Mongolian gerbils, early-life stress impaired the detection of short gaps in sound critical for speech perception, accompanied by reduced neural responses in auditory cortex, auditory periphery, and auditory brainstem. These findings suggest that early-life stress degrades sensory representations and could contribute to cognitive problems associated with early-life stress.

Summary: Memory encoding and retrieval are important processes in episodic memory, with the hippocampus playing a key role. However, the connectivity between the hippocampus and neocortex during memory processing in humans is not well understood. This study used data from two large-scale functional resonance imaging studies to identify hippocampal-cortical networks active during memory tasks. The functional connectivity maps were similar during resting state, encoding, and retrieval, and the connectivity profiles of the anterior and posterior hippocampus were stable across different states. During retrieval, the hippocampal connectivity with areas involved in recollection increased, while encoding connectivity likely reflected contextual factors.

Summary: This paper proposes a cognitive model called STEM-ADL, which encodes event sequences to predict the type and starting time of daily self-care activities. Experimental results demonstrate that STEM-ADL outperforms other models and is suitable for real-life healthcare applications.

Summary: In this study, the impact of emotion on memory was investigated using direct brain recording and deep brain stimulation. The findings show that emotional events have a significant influence on memory storage, with the brain prioritizing emotional information. Additionally, individuals with depression were found to have deficits in emotion-mediated memory and brain activity.

Summary: According to the encoding specificity hypothesis, memory is best recalled by retrieval cues that overlap with training cues. This hypothesis is supported by human studies. In this study, engrams in mice were visualized to test whether retrieval cues that overlap with training cues produce maximal memory recall via high engram reactivation. The findings support the encoding specificity hypothesis and emphasize the interaction between stored information (engram) and cues available at memory retrieval (ecphory).

Summary: A novel method called ODHUC is proposed for both uni-modal and cross-modal retrieval. It adopts an online deep hashing approach to continuously learn hash codes by sampling and updating the model. ODHUC also avoids forgetting old knowledge through knowledge distillation. Experimental results demonstrate that ODHUC outperforms other methods.

Summary: A recent paper suggests that psilocybin therapy can decrease brain network modularity in patients with depression, which is not found with the selective serotonin reuptake inhibitor S-citalopram. However, there are several issues raised regarding the inconsistencies in clinical outcomes, statistical flaws, and overinterpretation of resting state data.
