Environmental enrichment and the sensory brain: the role of enrichment in remediating brain injury
TLDR
The role of EE in the treatment of experimental TBI is addressed, where the demonstrated sensorimotor and cognitive benefits associated with exposure to EE, and their possible mechanisms are discussed.
Experience-dependent plasticity in early stations of sensory processing in mature brains: effects of environmental enrichment on dendrite measures in trigeminal nuclei
TLDR
A ubiquity of experience-dependent changes should not be overlooked when interpreting neuroplasticity and developing plasticity-based therapeutic strategies, as it also occurs at subcortical and even peripheral levels.
Environment and brain plasticity: towards an endogenous pharmacotherapy.
TLDR
This survey aims to review past and recent work concerning the influence exerted by the environment on brain plasticity processes, with special emphasis on the underlying cellular and molecular mechanisms and starting from experimental work on animal models to move to highly relevant work performed in humans.
Optical imaging of the rat brain suggests a previously missing link between top-down and bottom-up nervous system function
TLDR
It is suggested that operating at the mesoscale level of brain organization, neuronal assemblies may provide a functional link between “bottom-up” cellular mechanisms and “top-down” cognitive ones within anatomically defined regions.
Sensory Input-Dependent Changes in Glutamatergic Neurotransmission- Related Genes and Proteins in the Adult Rat Trigeminal Ganglion
TLDR
The results show that sustained changes in sensory input induce modifications in glutamatergic transmission-related gene expression in the TG, thus supporting a role for this early sensory-processing node in experience-dependent plasticity.
ENHANCING PLASTICITY WITH FLUOXETINE AND ENRICHMENT IN THE ADULT RAT CORTEX
TLDR
The effects of fluoxetine, alone or in combination with monocular deprivation (MD), in the adult rat visual cortex is investigated and the impact of shortand long-term enrichment in theAdult rat somatomotor cortex is examined.
Environmental Enrichment Sharpens Sensory Acuity by Enhancing Information Coding in Barrel Cortex and Premotor Cortex
TLDR
It is found that tactile enrichment improved tactile stimulus feature discrimination and the neural correlate of such improvement was revealed by analyzing single-cell information coding in both the primary somatosensory cortex and the premotor cortex of awake behaving animals.
Enrichment drives emergence of functional columns and improves sensory coding in the whisker map in L2/3 of mouse S1
TLDR
Enrichment drives emergence of functional columnar topography in S1, and reduces local tuning heterogeneity in L2/3, and these changes predict better touch detection by neural populations within each column.

Effects of urethane anaesthesia on sensory processing in the rat barrel cortex revealed by combined optical imaging and electrophysiology
TLDR
Comparisons of somatosensory‐evoked potentials (SEPs) with voltage‐sensitive dye imaging responses in the rat barrel cortex evoked by whisker deflection provide information regarding the impact of anaesthetic agents on the brain, and show the value of combining spatial analyses from neuroimaging approaches with more traditional electrophysiological techniques.
Environmental enrichment alters organizational features of the forepaw representation in the primary somatosensory cortex of adult rats
TLDR
The view that cortical cutaneous maps are maintained in a permanent state of use-dependent fluctuation is corroborates the view that environmental enrichment induced alterations in the representational features of the SI cutaneous map of the forepaw.
Plasticity in primary somatosensory cortex resulting from environmentally enriched stimulation and sensory discrimination training.
TLDR
Primary-somatosensory cortical plasticity due to selective stimulation of the sensory periphery by two procedures of active exploration in adult rats is argued to be consistent with the predictions of competitive Hebbian network plasticity.
Long-Term Plasticity in Mouse Sensorimotor Circuits after Rhythmic Whisker Stimulation
TLDR
It is shown that a brief period of rhythmic whisker stimulation in anesthetized mice resulted in a frequency-specific long-lasting increase in the amplitude of somatosensory-evoked potentials in the contralateral primary somatoensory (barrel) cortex, suggesting that natural, rhythmic patterns of whisker activity can modify the cerebral processing of sensory information.
Imaging Spatiotemporal Dynamics of Surround Inhibition in the Barrels Somatosensory Cortex
TLDR
The present findings shed new light on the spatial parameters of the intricate spatiotemporal cortical interplay of inhibition and excitation of rats anesthetized with urethane.
Naturalistic experience transforms sensory maps in the adult cortex of caged animals
TLDR
It is reported that the transfer of adult rats reared in standard laboratory cages to a naturalistic habitat modifies the functional and morphological organization of the facial whisker representation in the somatosensory ‘barrel’ cortex.
