O que é o Sistema Nervoso?
The nervous system is the collection of specialized cells responsible for maintaining an organism’s internal environment and coordinating the…
O Sistema Nervoso Parassimpático
The parasympathetic nervous system is one of the two major divisions of the autonomic nervous system. This parasympathetic system is responsible…
O Sistema Nervoso Simpático
The sympathetic nervous system—one of the two major divisions of the autonomic nervous system—is activated in times of stress. It…
A Barreira Hematoencefálica
The blood-brain barrier (BBB) refers to the specialized vasculature that provides the brain with nutrients in the blood while strictly regulating…
Estrutura do Neurónio
Neurons are the main type of cell in the nervous system that generate and transmit electrochemical signals. They primarily communicate with each…
A Sinapse
Neurons communicate with one another by passing on their electrical signals to other neurons. A synapse is the location where two neurons meet to…
Células da Glia
Glial cells are one of the two main types of cells in the nervous system. Glia cells comprise astrocytes, oligodendrocytes, microglia, and…
O Potencial de Membrana em Repouso
The relative difference in electrical charge, or voltage, between the inside and the outside of a cell membrane, is called the membrane potential.…
Potenciais de Ação
Neurons communicate by firing action potentials—the electrochemical signal that is propagated along the axon. The signal results in the…
Potenciação a Longo Prazo
Long-term potentiation, or LTP, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in…
Depressão a Longo Prazo
Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in…
Immunostaining para Visualize Murino desenvolvimento do sistema nervoso entérico
The enteric nervous system is formed by neural crest cells that proliferate, migrate and colonize the gut. Following colonization, neural crest cells…
Engenharia de tecidos tridimensionais alinhado Astrocyte redes para recapitular os mecanismos do desenvolvimento e facilitar a regeneração do sistema nervoso
Neurotrauma and neurodegenerative disease often result in lasting neurological deficits due to the limited capacity of the central nervous system…
<em>Drosophila no Vivo</em> lesão modelo para o estudo de Epilepsias na periferia e sistema nervoso Central
The regrowth capacity of damaged neurons governs neuroregeneration and functional recovery after nervous system trauma. Over the past few decades,…
