Sistema nervioso

¿Qué es un sistema nervioso?
The nervous system is the collection of specialized cells responsible for maintaining an organism’s internal environment and coordinating the…
El sistema nervioso parasimpático
The parasympathetic nervous system is one of the two major divisions of the autonomic nervous system. This parasympathetic system is responsible…
El sistema nervioso simpático
The sympathetic nervous system—one of the two major divisions of the autonomic nervous system—is activated in times of stress. It…
La barrera hematoencefálica
The blood-brain barrier (BBB) refers to the specialized vasculature that provides the brain with nutrients in the blood while strictly regulating…
La estructura neuronal
Neurons are the main type of cell in the nervous system that generate and transmit electrochemical signals. They primarily communicate with each…
La sinapsis
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 gliales
Glial cells are one of the two main types of cells in the nervous system. Glia cells comprise astrocytes, oligodendrocytes, microglia, and…
El potencial de membrana en reposo
The relative difference in electrical charge, or voltage, between the inside and the outside of a cell membrane, is called the membrane potential.…
Los potenciales de acción
Neurons communicate by firing action potentials—the electrochemical signal that is propagated along the axon. The signal results in the…
La potenciación a largo plazo
Long-term potentiation, or LTP, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in…
La depresión a largo plazo
Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in…
La inmunotinción para visualizar murino entérica Desarrollo del Sistema Nervioso
The enteric nervous system is formed by neural crest cells that proliferate, migrate and colonize the gut. Following colonization, neural crest cells…
Ingeniería tisular tridimensional alineado astrositos redes para recapitular los mecanismos del desarrollo y facilitar la regeneración del sistema nervioso
Neurotrauma and neurodegenerative disease often result in lasting neurological deficits due to the limited capacity of the central nervous system…
Un modelo de lesión de <em>Drosophila en Vivo</em> para el estudio de Neurorregeneración en el periférico y sistema nervioso Central
The regrowth capacity of damaged neurons governs neuroregeneration and functional recovery after nervous system trauma. Over the past few decades,…
