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.
When was TTX Company created?
TTX Company was created in 1955-12.
What is the motto of TTX Company?
TTX Company's motto is 'Forward thinking'.
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.
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
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.
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 effect does cannabis have on the neurons?
Marijuana is considered agonistic- it enhances the effects of neurotransmitters.
What is dryness fraction?
See OUSL course TTX 5234
What type of drug test doese ttx do?

Can the neurons in the brain be alterd?
Drugs can act in various regions of the brain to exert their effects.
What is the structure of the bonds in tetrodotoxin?
