Are there bidirectional neurons?
Neurons are mostly unidirectional, i.e. electrical impulses enter from one end and leave through the other. Are there bidirectional neurons as well, i.e., neurons that have a receiving end and a transmitting end that are not mutually exclusive?

Can non-spiking neurons have a sustained synaptic output current?
I'm trying to better understand neural models, specifically non-spiking neurons in invertebrate motor control circuits. I know that a spiking neuron produces spikes in membrane potential that rapidly go away and exhibit an all-or-none response. …

get signal from eye neurons
Hi guys you know some scientists could get electronic signals from brain and move it to muscles (full article here)
My question is: can we get signal from eye neurons and analyze it with a computer and after that see what he/she/it is seeing?
If…

Effect of number of post-synaptic neurons, and of inhibitory neuron/synapse, on post-synaptic neuron potential
I need to know which of the following statements are correct, if any:
1)
[pre]------>[post]
Single postsynaptic neuron: when [pre] fires, [post] fires, too (a single spike is enough to make the postsynaptic neuron's potential cross its threshold).…

What happens to the endplate potentials on the muscle fibre when the firing frequency of the motoneuron decreases?
A multiple choice question I came across which confused me a little. The options were:
A)The amplitude decreases
B)The duration decreases
C)The frequency decreases
I know that the force of contraction of a muscle fiber decreases when the frequency…
