Dictionary » P » Potentiation



(Science: physiology) increase in quantal release at a synapse following repetitive stimulation. Whereas facilitation at synapses lasts a few hundred milliseconds, potentiation may last minutes to hours.

(Science: pharmacology) The synergistic action of two drugs, being greater than the sum of the effects of each used alone.

Origin: L. Potentia = power

How are memories created?

... this that isn't known, and a lot of current theory is barely confirmed. It seems to change the membranes, initiating something called long-term potentiation (LTP).

Re: electric shock and memory

... or amygdala (for emotional memory). Long-term memory, on the other hand, is stored in some form of synaptic plasticity, such as long-term potentiation or long-term depression and therefore is not affected by electrical shock. LTP and LTD involve the number of receptors (AMPA receptors). ...

Hi All! I need to describe the processes involved in the "potentiation of an action potential". While I have a fairly good understanding of the general processes involved in the firing of neurons, I'm confused as to what "potentiation" ...

Nerve Memory

... connections between nerves being involved in memory - I'm not sure that means "nerve endings," though. Check the term "long term potentiation," or "LTP," and you should find a bit of information.

Curious... about the human brain...

... understood. The things we do know is that it has to do both with the creation of new synapses, and both with a phenomenon called long-term potentiation. This long term potentiation is a process by which a neuron keeps firing impulses even after the signal that came from a synapse is over. ...
