STDP-Driven Rewiring in Spiking Neural Networks under Stimulus-Induced and Spontaneous Activity

open access: yesBiomimetics, 2023
Mathematical and computer simulation of learning in living neural networks have typically focused on changes in the efficiency of synaptic connections represented by synaptic weights in the models. Synaptic plasticity is believed to be the cellular basis

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.

The Contribution of Thalamocortical Core and Matrix Pathways to Sleep Spindles. [PDF]

open access: yes, 2016
Sleep spindles arise from the interaction of thalamic and cortical neurons. Neurons in the thalamic reticular nucleus (TRN) inhibit thalamocortical neurons, which in turn excite the TRN and cortical neurons.

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 ...

Rapid, learning-induced inhibitory synaptogenesis in murine barrel field [PDF]

open access: yes, 2010
The structure of neurons changes during development and in response to injury or alteration in sensory experience. Changes occur in the number, shape, and dimensions of dendritic spines together with their synapses. However, precise data on these changes

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 ...
