Maternal licking and grooming (LG) in infancy influences stress responsiveness and cognitive performance in the offspring. We examined the effects of variation in the frequency of pup LG on morphological, electrophysiological, and behavioral aspects of hippocampal synaptic plasticity under basal and stress-like conditions. We found shorter dendritic branch length and lower spine density in CA1 cells from the adult offspring of low compared with high LG offspring. We also observed dramatic…

Maternal care determines rapid effects of stress mediators on synaptic plasticity in adult rat hippocampal dentate gyrus
Maternal Care Differentially Affects Neuronal Excitability and Synaptic Plasticity in the Dorsal and Ventral Hippocampus
It is reported that variations in maternal care in the rat associate with opposing effects on hippocampal function in the dorsal and ventral hippocampus, and region-specific influences of maternal Care in shaping neural development and synaptic plasticity are suggested.
Adult hippocampal glucocorticoid receptor expression and dentate synaptic plasticity correlate with maternal care received by individuals early in life
It is concluded that even moderate variations in early life environment have a major impact on adult hippocampal function and could provide a mechanistic basis for individual differences in susceptibility to psychopathology.

This study shows that the changes that are induced by the early-life environment might be adaptive: moderate levels of deprivation and stress during development might prepare individuals for a tough life, allowing them to cope better in stressful circumstances.
Generalization of Conditioned Auditory Fear is Regulated by Maternal Effects on Ventral Hippocampal Synaptic Plasticity
It is suggested that rearing by low LG dams enhances the efficacy of fear-related neural systems to support accurate encoding of fear memories through effects on the VH.
Effect of maternal separation and chronic stress on hippocampal-dependent memory in young adult rats: evidence for the match-mismatch hypothesis
An interaction between early environment experiences and chronic variable stress in young adulthood is shown as evidence that early stressful experiences do not necessarily lead to a negative outcome but can help in maintaining brain plasticity and increase fitness when animals reach adulthood.
Intensification of maternal care by double‐mothering boosts cognitive function and hippocampal morphology in the adult offspring
It is demonstrated that double‐mothering exerts a long‐term positive control on cognitive function and hippocampal neuronal connectivity and might offer a concrete possibility to limit or reverse the consequences of negative predisposing conditions for normal cognitive development.
Severe Early Life Stress Hampers Spatial Learning and Neurogenesis, but Improves Hippocampal Synaptic Plasticity and Emotional Learning under High-Stress Conditions in Adulthood
Early life stress increases the risk for developing stress-related pathologies later in life. Recent studies in rats suggest that mild early life stress, rather than being overall unfavorable, may


Peripubertal environmental enrichment reverses the effects of maternal care on hippocampal development and glutamate receptor subunit expression
Findings suggest that environmental enrichment reverses the effects of reduced maternal care through the same genomic target, the NR2B gene, and possibly effects on other subunits of the NMDA and AMPA receptors.
Chronic unpredictable stress impairs long‐term potentiation in rat hippocampal CA1 area and dentate gyrus in vitro
Exposure to chronic variable stress per se reduces synaptic plasticity both in CA1 and dentate gyrus and acute rises in corticosterone level induce no additional impairment of synaptic Plasticity in the CA1 region of chronically stressed rats.
Variations of maternal care alter offspring levels of behavioural defensiveness in adulthood: Evidence for a threshold model
Variations in Maternal Care Alter GABAA Receptor Subunit Expression in Brain Regions Associated with Fear
Findings are consistent with earlier reports of the effects of maternal care on GABAA/benzodiazepine receptor binding and suggest that maternal care can permanently alter the subunit composition of the GAB AA receptor complex in brain regions that regulate responses to stress.
Opposite effects of glucocorticoid receptor activation on hippocampal CA1 dendritic complexity in chronically stressed and handled animals
It is concluded that brief exposure to high concentrations of corticosterone can differently affect apical dendritic structure, depending on the earlier history of the animal, a process that critically depends on involvement of the glucocorticoid receptor.
Epigenetic programming by maternal behavior
It is shown that an epigenomic state of a gene can be established through behavioral programming, and it is potentially reversible, suggesting a causal relation among epigenomicState, GR expression and the maternal effect on stress responses in the offspring.
Importance of early lighting conditions in maternal care by dam as well as anxiety and memory later in life of offspring
Findings suggested that ELC affect mother–infant interactions and subsequently at least partially alter the neurobehavioral development of offspring.
Maternal care during infancy regulates the development of neural systems mediating the expression of fearfulness in the rat.
It is suggested that maternal care during infancy serves to "program" behavioral responses to stress in the offspring by altering the development of the neural systems that mediate fearfulness.
