Furthermore, whole-cell patch-clamp was employed to determine IGF-1 effects on ARHKisspeptin neuron's resting membrane potential (RMP). FURA-2 was incorporated by 64 ARHKisspeptin neurons out of 424 cells in the ARH. IGF-1 administration to the bath led to a significant increase of the ...
As a new paradigm for neuroscience, neural network models have the potential to incorporate knowledge acquired with single-neuron approaches to help us understand how emergent functional states generate behaviour, cognition and mental disease.

The spike generator is located at the beginning of the axon, that is, where the axon meets the soma of the cell. When the neuron generates a spike, the membrane potential suddenly and briefly jumps to a positive value (e.g., 30 mV) and then returns to the resting potential. To a ...
As K+ ions leave the cell, the membrane potential once again becomes negative. The diffusion of K+ out of the cell actually hyperpolarizes the cell, in that the membrane potential becomes more negative than the cell’s normal resting potential. At this point, the sodium channels will return...
h, iEEG ITPC in response to a 40-Hz click-train in wakefulness (top), and associated Event-Related Potential (ERP) (bottom). i, Scatter plot of ITPC in response to 40-Hz click-trains during NREM sleep (y axis) versus wakefulness (x axis). Inset and format as in panel c. Each ...
How is the resting membrane potential of a neuron produced and maintained? Explain the functions of astrocytes in a normally functioning nervous system. What is the difference between central nervous system and PNS? Describe the neuromuscular junction, and explain how action potentials in the...
Instead, for each protein of interest, a potential solution needs to be identified and the obtained constructs then carefully tested in cells and finally in the animal. Despite these complications, the advantages of acute protein manipulation to dissect cellular processes during development are so ...
ACh or carbachol (30 μm) caused inward currents in neurones voltage-clamped near the resting potential. These currents reversed polarity at around −4mV, were blocked by hexamethonium (1–100 μm) in a voltage-dependent manner, and showed desensitization with prolonged or repeated agonist ap...
These studies confirm the neuronal origin of IM-PEN which have a depolarized resting membrane potential due to high internal chloride concentration.
