Action potentials of an earthworm going negative first

Ok so for a bit of a background, I am doing a science project looking at the action potentials of the earthworm. I anaesthatized the worms then hooked them up to a spiker box (http://backyardbrains.com/products/spikerbox) and stimulated them. This is an average result: ...

Re: Do We Have The Freedom Of Choice?

... it makes you wonder if it really exists. Human beings are not just bunch of cells but we are souls inhabiting a building of cells depending on our potentials, to help us grow (just as cells grow by food, souls grow by knowledge). Science has not yet proven the existence of souls, so it can't prove ...

Why do neurones only have one axon?

... regular intervals called nodes of ranvier where diffusion of ions can occur. If we had lots of axons there would be loads of gaps and the action potentials or nerve impulses would become reduced and would probably not transmit a signal strong enough to trigger a response. It is and interesting ...

Re: plants' intelligence (neurosensing)

... species. As for electricity, wiki says this: "Plant cells can be electrically excitable and can display rapid electrical responses (action potentials) to environmental stimuli. These action potentials can influence processes such as actin-based cytoplasmic streaming, plant organ movements, ...

Stimulus intensity?!!!

How is stimulus intensity encoded in your (all-or-nothing) Action Potentials? e.g. the strength of a handshake in a sensory neuron. Thanks :)
