Mnemonic functions, supporting rodent behavior in complex tasks, include both long-term and (short-term) working memory components. While working memory is thought to rely on persistent activity states in an active neural network, long-term memory and synaptic plasticity contribute to the formation of the underlying synaptic structure, determining the range of possible states. Whereas, the implication of working memory in executive functions, mediated by the prefrontal cortex (PFC) in primates and rodents, has been extensively studied, the contribution of long-term memory component to these tasks received little attention. This review summarizes available experimental data and theoretical work concerning cellular mechanisms of synaptic plasticity in the medial region of rodent PFC and the link between plasticity, memory and behavior in PFC-dependent tasks. A special attention is devoted to unique properties of dopaminergic modulation of prefrontal synaptic plasticity and its contribution to executive functions.

Fragile X syndrome (FXS) is an inherited neurodevelopmental disorder characterized by a range of clinical manifestations with no effective treatment strategy to date. Here, transplantation of GABAergic precursor cells from the medial ganglionic eminence (MGE) is demonstrated to significantly improve cognitive performance in Fmr1 knockout (KO) mice. Within the hippocampus of Fmr1-KO mice, MGE-derived cells from wild-type donor mice survive, migrate, differentiate into functionally mature interneurons, and form inhibitory synaptic connections with host pyramidal neurons.

In this study, we explored the biocultural mechanisms underlying ancient craft behaviours. Archaeological methods were integrated with neuroscience techniques to explore the impact on neuroplasticity resulting from the introduction of early pottery techniques. The advent of ceramic marked a profound change in the economy and socio-cultural dynamics of past societies.

Postoperative delirium (POD), an acute cognitive dysfunction linked to morbidity and mortality, is characterized by memory impairments and disturbances in consciousness, particularly in patients aged 65 and older. Neuroinflammation and NAD+ imbalance are key mechanisms behind POD, leading to synaptic and cognitive deterioration. However, how surgery contributes to POD and neuroinflammation remains unclear, and effective treatments are lacking.

The brain plays a vital role in maintaining homeostasis and effective interaction with the environment, shaped by genetic and environmental factors throughout neurodevelopment and maturity. While genetic components dictate initial neurodevelopment stages, epigenetics-specifically neuroepigenetics-modulates gene expression in response to environmental influences, allowing for brain adaptability and plasticity. This interplay is particularly evident in neuropathologies like Rett syndrome and CDKL5 deficiency syndrome, where disruptions in neuroepigenetic processes underline significant cognitive and motor impairments.
