Structural Plasticity in Neuronal Networks [PDF]

open access: yes, 2007
Neuronal networks are established during development by the formation of connections (synapses) between neurons. Once formed, these synapses undergo experience-dependent modifications throughout the lifespan of the animal (synaptic plasticity ...

Gochnatia polymorpha (Less.) Cabrera (Asteraceae) changes in leaf structure due to differences in light and edaphic conditions Gochnatia polymorpha (Less.) Cabrera modifica sua estrutura foliar devido a diferenças na luminosidade e condições edáficas

open access: yesActa Botânica Brasílica, 2010
Gochnatia polymorpha (Less.) Cabrera is a widespread Asteraceae species found in different physiognomies of cerrado (Neotropical savanna) and in forest formations of southeast Brazil. This study describes some leaf anatomy characteristics of this species

Quantitative effects of environmental variation on stomatal anatomy and gas exchange in a grass model

open access: yesQuantitative Plant Biology, 2022
Stomata are cellular pores on the leaf epidermis that allow plants to regulate carbon assimilation and water loss. Stomata integrate environmental signals to regulate pore apertures and adapt gas exchange to fluctuating conditions.

Structural plasticity of synaptic connectivity in the adult hippocampal mossy fiber projection [PDF]

open access: yes, 2013
The brain has the lifelong ability to change itself based on new experiences such as learning and memory. This so called neuronal plasticity is reflected in the brain by structural and functional modifications which underlie our ability to learn ...

Leaf physiological and structural plasticity of two Asplenium (Aspleniaceae) species coexisting in sun and shade conditions [PDF]

open access: yesPlant Ecology and Evolution, 2019
Background and aims – Relatively few studies have addressed the sun-shade response of fern species. Moreover, there is no information on species-specific plasticity patterns of such response, their relationship with species ecological requirements and ...

Microstructural differences in the thalamus and thalamic radiations in the congenitally deaf. [PDF]

open access: yes, 2014
There is evidence of both crossmodal and intermodal plasticity in the deaf brain. Here, we investigated whether sub-cortical plasticity, specifically of the thalamus, contributed to this reorganisation. We contrasted diffusion weighted magnetic resonance

Neuroimmune System as a Driving Force for Plasticity Following CNS Injury

open access: yesFrontiers in Cellular Neuroscience, 2020
Following an injury to the central nervous system (CNS), spontaneous plasticity is observed throughout the neuraxis and affects multiple key circuits.

Phenotypic plasticity in Copaifera langsdorffii Desf. in different forest fragments in São Paulo state, Brazil [PDF]

open access: yesAnais da Academia Brasileira de Ciências, 2022
Forest fragments are susceptible to environmental shifts and this demands high phenotypic plasticity of the species growing in these areas. In this context, the objective of the present work was to study the phenotypic plasticity of copaíba (Copaifera ...
