We can be thankful that they go in only one direction; otherwise brain activity would be nothing but chaos. Neurotransmission begins at the synapse. At the synapse, only one of the two corresponding neurons has receptor locations that determine whether or not the receiving neuron will fire. The other neuron at the synapse is responsible for producing the neurotransmitters that attach to the receptors. There is sometimes a re-uptake of neurotransmitters when there are no more receptors for them to attach to. Some psychotropic drugs work to inhibit this re-uptake.

Why is conduction at synapses one way?
Neurotransmitters are only produced from one side.
How is one-way conduction at synapses ensured?
Absolute refractory period (time which local area of the membrane has surpassed the threshold potential and will not respond to any stimulus).
How are heat and conduction related?
Conduction is one way that heat spreads.
Why cant energy travel by conduction through empty space?
Conduction requires the presence of matter. The way conduction works, one atom or molecule bumps into another one, transferring heat energy.
What is a way of conduction?
This means that the flow of a nerve impulse will travel only in one direction.
Why can heat not travel by conduction through a vacuum when there is no particles?
Conduction requires the presence of matter. The way conduction works is that one molecule bumps into another molecule, transferring energy. This mechanism, obviously, requires the presence of molecules.
What a example of conduction?
A good example of conduction is the way your electric stove heats the pot. On contact, the heat from the burner transfers to the pot through conduction.
Is conduction a way that energy is transferred?
yes
Why conduction at synapses is always one-way?
There are two basic reasons. One is that chemical transmission only affects the side in the synapse that have specific receptors for the neurotransmitter released, secondly the presynaptic terminal has been depolarized and is in it's refractory period, where it can not again fire. This is also the reason why the travelling wave of the action potential only travels from the axon hillock where the AP is generated towards the nerve terminal. There is, however, one caveat to this 'rule'. In the CA1 region of the hippocampus there is a retrograde signal from the postsynaptic neuron back to the presynaptic side using the gas NO as the 'transmitter'.
Is a solid liquid or gas sread by conduction?
Conduction is a form of heat transfer. The other forms are radiation and convection. Conduction is the normal way for heat to spread throughout a solid object. Convection is the normal way for gases and liquids.
If you are cold which method is the fastest way to get warm?
conduction
When a warmer object touches a cooler object what does heat move by?
if you mean to what way it transfer, always the heat is going to move to the cooler object. The means of heat transfer is conduction.
