Equally surprising is the fact that the concept of chemical transmission in the brain was not known until around 1930 (Henry Hallett Dale and Otto Loewi). We began to understand the basic electrical phenomenon that neurons use in order to communicate among themselves, the action potential, in the 1950s ( Alan Lloyd Hodgkin , Andrew Huxley and ...
Chemical synapses are biological junctions through which neurons' signals can be sent to each other and to non-neuronal cells such as those in muscles or glands. Chemical synapses allow neurons to form circuits within the central nervous system. They are crucial to the biological computations that underlie perception and thought.
Diagram of a chemical synaptic connection. In the nervous system, a synapse [1] is a structure that allows a neuron (or nerve cell) to pass an electrical or chemical signal to another neuron or a target effector cell. Synapses can be classified as either chemical or electrical, depending on the mechanism of signal transmission between neurons.
[1] A connectome (/ k ə ˈ n ɛ k t oʊ m /) is a comprehensive map of neural connections in the brain, and may be thought of as its "wiring diagram". [2] An organism's nervous system is made up of neurons which communicate through synapses. A connectome is constructed by tracing the neuron in a nervous system and mapping where neurons are ...
Autocrine signaling occurs when the chemical signal acts on the same cell that produced the signaling chemical. [1] Intracrine signaling occurs when the chemical signal produced by a cell acts on receptors located in the cytoplasm or nucleus of the same cell. [2] Juxtacrine signaling occurs between physically adjacent cells. [3]

Signal transduction is the process by which a chemical or physical signal is transmitted through a cell as a series of molecular events.Proteins responsible for detecting stimuli are generally termed receptors, although in some cases the term sensor is used. [1]
CD rates strongly track with the key interest rate set by the Federal Reserve, the U.S.'s central bank. This Fed rate is the benchmark that affects rates on deposit accounts, loans, mortgages ...
