How does cortical electrical activity arises?5 answersCortical electrical activity arises through the interaction of various factors. The development of cortical EEG activity, membrane and action potentials, and surface steady potentials occurs from the early postnatal days in rats, with resting cellular membrane potentials and surface steady potentials present from the first day on. Action potentials from cortical neurons are detectable from the fourth day and are preceded by rhythmical oscillations in membrane potential resembling excitatory postsynaptic potentials. In addition, a continuum model of the electrical activity of the cerebral cortex predicts the occurrence of a resonance in the gamma range near 40 Hz, which emerges due to refinements in the model, including the modulation of synaptic strength and parameters that match physiological measurements. The coordination of neuronal activity in an isolated cortical slab during the onset of seizure spikes is also observed, with convulsive shifts in membrane potential corresponding to electrocorticograms of convulsive activity waves. These findings suggest that cortical electrical activity arises from the interplay of synaptic connections, membrane potentials, and coordinated neuronal activity.

4 answers
Multi-Copper Oxidases (MCOs) play a pivotal role in various physiological processes in plants, ranging from iron homeostasis to lignification, and even in defense mechanisms against pathogens. MCOs, including laccase-like multi-copper oxidases (LMCOs), are involved in the oxidation of numerous substrates, linking the four-electron reduction of molecular oxygen to water, which is crucial for processes such as lignification. Specifically, MCO1 and MCO3 have been identified as functional ferroxidases that participate in the control of iron transport within mesophyll cells, suggesting a role in maintaining iron homeostasis by modulating the Fe2+/Fe3+ balance in the apoplast, thereby limiting excessive iron accumulation. This is critical as iron is an essential metal ion that serves as a cofactor in many biological processes, and its balance is central to cellular homeostasis. Furthermore, LMCOs have been associated with the process of lignification in plants, acting as markers for highly localized lignification events in tissues not typically considered lignified. This suggests their involvement in the structural integrity and defense mechanisms of plants. The expression patterns of specific Arabidopsis thaliana LMCO family members also indicate their role in early root development and possibly in the formation of suberin in the Casparian strip of root endodermis, highlighting their importance in plant development and stress responses. Additionally, MCOs are implicated in plant defense mechanisms. For instance, magnesium oxide-induced defense responses against Ralstonia solanacearum in Arabidopsis thaliana suggest that MCOs might be involved in signaling pathways that activate plant defenses. Moreover, the interaction of MLO proteins with syntaxins, which are related to MCO functions, points towards a role in modulating plant immunity against pathogens like powdery mildew fungi. In summary, MCOs in plants are integral to a wide array of biological functions, including iron homeostasis, lignification, development, and defense against pathogens, underscoring their multifaceted roles in plant physiology and stress responses.
