study. An agonist is any chemical substance that binds to the receptor sites on the postsynaptic neuron causing the neuron to fire.

Neurotransmitters are the body endogenous agonists that bind to receptor sites on the postsynaptic neuron causing the neuron to fire.

One example of one endogenous agonist is acetylcholine. Antonova wanted to investigate if scopolamine (which is an antagonist for acetylcholine) affected hippocampal activity in the creation of spatial memory.

The researcher used a sample that was made up of only males, it was a double blind study.

The p.s were allocated into two conditions, in one condition the participants were injected with scopolamine (which is a drug that blocks acetylcholine receptors) and in the other condition they were injected with placebo.
