Nervensystem

Was ist ein Nervensystem?
The nervous system is the collection of specialized cells responsible for maintaining an organism’s internal environment and coordinating the…
Das Parasympathische Nervensystem
The parasympathetic nervous system is one of the two major divisions of the autonomic nervous system. This parasympathetic system is responsible…
Das sympathische Nervensystem
The sympathetic nervous system—one of the two major divisions of the autonomic nervous system—is activated in times of stress. It…
Die Blut-Hirn-Schranke
The blood-brain barrier (BBB) refers to the specialized vasculature that provides the brain with nutrients in the blood while strictly regulating…
Neuron Struktur
Neurons are the main type of cell in the nervous system that generate and transmit electrochemical signals. They primarily communicate with each…
Die Synapse
Neurons communicate with one another by passing on their electrical signals to other neurons. A synapse is the location where two neurons meet to…
Gliazellen
Glial cells are one of the two main types of cells in the nervous system. Glia cells comprise astrocytes, oligodendrocytes, microglia, and…
Das Ruhepotenzial der Membranen
The relative difference in electrical charge, or voltage, between the inside and the outside of a cell membrane, is called the membrane potential.…
Aktionspotenziale
Neurons communicate by firing action potentials—the electrochemical signal that is propagated along the axon. The signal results in the…
Langfristige Potenzierung
Long-term potentiation, or LTP, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in…
Langfristige Depression
Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in…
Immunfärbung zu Murine enterische Nervensystem Entwicklung visualisieren
The enteric nervous system is formed by neural crest cells that proliferate, migrate and colonize the gut. Following colonization, neural crest cells…
Dreidimensionale Gewebezüchtungen ausgerichtet Astrozyten Netzwerke Nervensystem Regeneration zu rekapitulieren Entwicklungsmechanismen
Neurotrauma and neurodegenerative disease often result in lasting neurological deficits due to the limited capacity of the central nervous system…
Eine <em>Drosophila In Vivo</em> Verletzungen Modell für das Studium Neuroregeneration in den peripheren und zentralen Nervensystems
The regrowth capacity of damaged neurons governs neuroregeneration and functional recovery after nervous system trauma. Over the past few decades,…
