Why is numbness experienced after eating puffer fish?
TTX (the poison in pufferfish) inhibits neurons that transmit sensory information to the brain. Since TTX prevents the generation of action potentials in sensory nerves, the ability of the neurons to transmit sensory information will be inhibited. This loss of sensory information would be experienced as a "numbness" in areas exposed to the toxin.
What is the motto of TTX Company?
TTX Company's motto is 'Forward thinking'.
When was TTX Company created?
TTX Company was created in 1955-12.
Why are fewer action potentials redorded at recording electrodes R2 when TTX is applied between R1 and R2?
TTX blocks voltage-gated sodium channels, which are necessary for action potential initiation and propagation. When TTX is applied, sodium influx is prevented, leading to a decrease in action potentials recorded at electrode R2 due to the inability of neurons to generate and transmit action potentials.
What does TTX do to voltage-gated Na channels?
Tetrodotoxin (TTX) is a natural inhibitor and blocks single sodium channels in an all-or-none manner.
Why are fewer action potentials recorded at R2 when TTX is aaplied between R1 and R2?
TTX will block the response at R1 but have no effect at R2
How does the effect of lidocaine differ from the effect of TTX?
They both decrease action potential duration, but TTX is the only one that decreases the maximum rate of depolarization.
What specific effects oes cafffine have on neurons?
The effect that caffeine has on neurons is to make them more sensitive to the effects of neurotransmitters. Caffeine lowers the threshold and makes the neurons more sensitive. This means it takes less of the neurotransmitter to affect another neuron.
What is dryness fraction?
See OUSL course TTX 5234
What type of drug test doese ttx do?
This ever get figured out?
What effect does cannabis have on the neurons?
Marijuana is considered agonistic- it enhances the effects of neurotransmitters.
Why are fewer action potentials recorded at R2 when TTX is applied between R1 and R2?
When tetrodotoxin (TTX) is applied between R1 and R2, it blocks voltage-gated sodium channels, preventing the influx of sodium ions necessary for depolarization during an action potential. As a result, the action potentials generated at R1 cannot propagate to R2, leading to fewer or no action potentials being recorded at R2. This illustrates the critical role of sodium channels in the transmission of electrical signals along neurons.
