What do you think would happen if the
dendrites could no longer receive
signals?

I think sorry if wrong ;)

These connections occur at short, root-like tendrils called dendrites, which sprout from the neuron's cell body, or soma. ... As it loses input connections, the wounded neuron also becomes more excitable: the neuron becomes more likely to fire signals down its truncated axon when stimulated to do so by other neurons.

protist eukaryotes that are not plants, animals, or fungi ("misfits")

life would be meaningless without memes
