Synaptic Poison: Understanding Changes in the Conduction of Nerve Impulses at Synapses

In neurobiology, there is the concept of “synaptic poison,” which describes the general name of substances that cause changes in the conduction of nerve impulses at synapses. These changes can be either strengthening or weakening of signals between neurons, and play an important role in the functioning of the nervous system.

Synapses are points of contact between neurons where information is transmitted through chemical signals. When a nerve impulse reaches a synapse, it causes the release of neurotransmitters such as glutamate or gamma-aminobutyric acid (GABA). These neurotransmitters bind to receptors on the postsynaptic membrane, resulting in changes in nerve signal transmission.

Synaptic poisons are a variety of substances that can affect this process. One of the most well-known synaptic poisons is botulinum toxin, which is produced by the bacterium Clostridium botulinum. Botulinum toxin blocks the release of neurotransmitters from presynaptic terminals, interfering with the transmission of nerve impulses. It results in muscle paralysis and is used medicinally to treat various muscle disorders.

At the same time, there are synaptic poisons that can enhance the conduction of nerve impulses. For example, some spider venoms contain toxins that activate calcium channels on the postsynaptic membrane, which enhances intrasynaptic signals and leads to stronger nerve impulses.

Research on synaptic poisons is important for understanding the mechanisms of functioning of the nervous system. They help expand our knowledge of the role of various neurotransmitters and receptors in signaling between neurons. In addition, synaptic poisons can serve as models for the development of new drugs that can improve or suppress signaling in the nervous system.

In conclusion, synaptic poisons are a general name for substances that cause changes in the conduction of nerve impulses at synapses. They can enhance or weaken signals between neurons and play an important role in the functioning of the nervous system. Research on synaptic venoms helps expand our understanding of the mechanisms of signal transmission in the nervous system and may have practical applications in drug development. Further research in this area could lead to new discoveries and breakthroughs that will help us better understand and treat various neurological and psychiatric disorders.



Synaptic transmission or synaptic transmission is a universal and basic phenomenon of electrical signals transmitted along synapses. Synapses are the areas of contact between two neurons, as well as neuromuscular or neuroepithelial synapses.
