Membrane Potentials and Action Potentials
Electrical potentials exist across the membranes of virtually all cells of the body. In addition, some cells, such as nerve and muscle cells, are capable of generating rapidly changing electrochemical impulses at their membranes, and these impulses are used to transmit signals along the nerve or muscle membranes. In other types of cells, such as glandular cells, macrophages, and ciliated cells,...

lntracellular Caz+, K+, CI-, and NOsactivities were measured with ion-selective microeledrodes in the liverwort Conocephalum conicum 1. at rest, during dark/light changes, and in the couese of adion potentials triggered by light or electrical stimuli. l h e average free cytosolic Caz+ concentration was 231 f 65 nM. We did not observe any light-dependent changes of the free cytosolic Caz+ concen...

Exploration of the cytoplasm of the giant esophageal cell of Ascaris with a recording microelectrode shows the existence of shallow spaces where the microelectrode tip becomes extracellular in spite of being in the interior of the cell. When the microelectrode penetrates into these spaces from the cytoplasm, the resting potential shifts to a different level or entirely disappears. At the same t...

The sustained activity seen in the oculomotor inteIntegrating with Action Potentials grator, like that shown in the figure, provides a representation of the running integral of the burst neuron inputs. Similar types of sustained activity have been seen in a When we add a long list of numbers in our heads, we number of brain areas in monkeys doing tasks that remust keep track of the running tota...
متن کاملIntegrating with Action Potentials
Similar types of sustained activity have been seen in a When we add a long list of numbers in our heads, we number of brain areas in monkeys doing tasks that remust keep track of the running total while performing quire short-term memory of transient stimuli (Fuster, the individual summations. Neural circuits integrating 1995). They have been interpreted in this context as a information must si...
