Cocaine is an ilicit drug that effects the brain's neurotransmitters and therefore senses. Cocaine's modality is:
increase serotonin in pre-synaptic neurons
antagonize the uptake of dopamine in the synaptic cleft, replacing dopamine with cocaine
decreases serotonin levels in post-synaptic neuron
mimics dopamine in the brain and therefore it's affects
Ecstasy is a drug that effects brain function. It's modality is:
aids in releasing excess serotonin
prevents opiod channel from functioning properly
antagonist for GABA
preventing the uptake of serotonin
There are over 100 different types of naturally occurring neurotransmitters in our body that serve different functions: they help us move around, keep our vital organs working, amp us up, calm us down, make us hungry, sleepy or more alert or make us feel good.
To end synaptic transmission, a neurotransmitter dissociates from its receptor and:
is pumped back into the presynaptic terminal in a process called reuptake.
is degraded (broken down by enzymes). The breakdown products are then taken up by the presynaptic cell and the neurotransmitter is resynthesized.
Both answers are correct. Both can occur when a neurotransmitter dissociates from its receptor.
