Addiction biology is the study of brain receptor chemistry. The interactions between nerve receptors, nerve synapses and drugs forms the basis for most treatments of brain disease. These same interactions are responsile for addiction.
Addiction is a response to receptor-ligand binding.
This is the model that best explains the effects drugs as well as those caused by hormones and neurotransmitters.
Nature provided cell membranes with receptors that recognize and bond with specific molecules. This capability allows cells to obey commands and to adapt to a changing environment. Proper interactions depend on functional molecules matching with its receptor on the membrane
Taste, color and odor molecules are wrapped inside a plant’s cells. These physical characteristics are determined by the chemical characters found in the whole plant. These plant compounds or ligands interact with neuronal receptors in the brain to initiate or block an activity.
Receptor- ligand binding is Nature’s on/off switches.
The coordination of these switches controls all brain activity, thoughts, and feelings.
