Surgery can be done in case a peripheral nerve has become cut or otherwise divided. This is called peripheral nerve reconstruction. The injured nerve is identified and exposed so that normal nerve tissue can be examined above and below the level of injury, usually with magnification, using either loupes or an operating microscope. If a large ...
The persistent sodium current (INaP) (also called the "late sodium current" or "non/slow-inactivating sodium current") is a form of sub-threshold, biological electric current contributed by non-inactivating voltage-gated sodium channels (NaVs) found in several central neurons. [1]
The axolotl is less commonly used than other vertebrates, but is still a classical model for examining regeneration and neurogenesis. Though the axolotl has made its place in biomedical research in terms of limb regeneration, [19] [20] the model organism has displayed a robust ability to generate new neurons following damage.
The ReMarkable Tablet won't, however, be a good replacement for a more conventional tablet like an iPad. It's not meant for the same function an iPad would provide, like surfing the Internet ...
A neuron of a given kind (e.g. a thalamic cell) cannot be functionally replaced by one of another type (e.g. an inferior ollivary cell) even if their synaptic connectivity and the type of neurotransmitter outputs are identical. (The difference is that the intrinsic electrophysiological properties of thalamic cells are extraordinarily different ...
One of the great strengths of this Tablet is its gorgeous 13-inch OLED display. Reading the crisp text that this display can reproduce is a pleasure. Watching a movie on it, more so.
Neurons communicate with one another via synapses. Synapses are specialized junctions between two cells in close apposition to one another. In a synapse, the neuron that sends the signal is the presynaptic neuron and the target cell receives that signal is the postsynaptic neuron or cell. Synapses can be either electrical or chemical.
Neuromodulation is the physiological process by which a given neuron uses one or more chemicals to regulate diverse populations of neurons. Neuromodulators typically bind to metabotropic, G-protein coupled receptors (GPCRs) to initiate a second messenger signaling cascade that induces a broad, long-lasting signal.
