The thing is a freak, and moreover completely off-topic. I demand Sheekle's head for his attempts to troll and derail this thread.

BlindSophist said: I know that LTP and LTD stand for "long term potentiation" and "long-term depression" respectively, which refers to the increasing or decreasing (respectively) tendency of two neurons to fire in synchronization, strengthening both of their signal outputs to other neurons. It's related to neuroplasticity because it alters the brain's reactions to stimuli over time as old networks decay and vanish while new ones are created.
That makes sense as I understand it. It would mean that the more the input occurs after the output, the less the two stimuli are linked together in a meaningful way.

Now THAT would be on topic. I'm liking this idea.

Oh come on, you are as clueless as I am. Don't even try to make us believe that you know what you're talking about lol.
Neuroscience is my minor and my life's passion, dude. I'm also trained in coming to conclusions based upon presented data, background knowledge and graphs/diagrams due to my excellent molecular biology class which was mainly focused on producing students able to do such a thing. I couldn't have come up with what she said on my own, because I'm certainly not at that educational level yet but analyzing her response along with the data presented and everything I know about neuroscience allows me to reasonably judge whether her response "seems" to be correct or not, like I said.
I don't see how me saying that her answer is reasonable, logical and seems correct is trying to make anyone believe I know what I'm talking about. If I had posted a paragraph trying to use the terms myself, I could see how you could come to that conclusion but as is I just am saying Penelope's conclusion seems valid based upon the data at hand and my background knowledge about neuroplasticity and excitatory postsynaptic potentials (which is a huge focus of a course I'm currently acing.)
Plus, it goes along with typical psychological responses in all animals: if a response occurs after a behavior, the organism is more likely to assume the two things are linked by causality whereas if the behavior occurs after a response, the organism isn't likely to think the two are causally linked. (Skinner's pigeon studies are one example.)

Well, the truth is that right now I couldn't answer the OP on my own, so it's not like I know everything there is about neuroplasticity or neurons. 
No problem dude, I think that's a pretty good example of the subject in your OP effecting behavior overally. Cool post, btw.

Amphetamines are actually not considered to have the ability to increase learning ability, they simply allow your neurons to fire faster and longer. This is especially helpful when needing to study long hours without fatigue. Basically they reverse fatigue, hence why they were invented (for narcolepsy) tho some nootropic effects are seen with some amphetamine salts that is not their primary function.. Memory and learning enhancement is do to neuron-plasticity and the amino acid glutamate. Many memory enhancing drugs work by inhibiting glutamate channels.
Quote:
Glutamate is the most abundant excitatory neurotransmitter in the vertebrate nervous system.[9] At chemical synapses, glutamate is stored in vesicles. Nerve impulses trigger release of glutamate from the pre-synaptic cell. In the opposing post-synaptic cell, glutamate receptors, such as the NMDA receptor, bind glutamate and are activated. Because of its role in synaptic plasticity, glutamate is involved in cognitive functions like learning and memory in the brain.[10] The form of plasticity known as long-term potentiation takes place at glutamatergic synapses in the hippocampus, neocortex, and other parts of the brain. Glutamate works not only as a point-to-point transmitter but also through spill-over synaptic crosstalk between synapses in which summation of glutamate released from a neighboring synapse creates extrasynaptic signaling/volume transmission.[11]

so how would inhibiting glutamate channels aid in memory storage and recall? it seems like glutamate is pretty useful in that stuff
