Document Summary
Right into the hippocampus or right into the ventricles to disperse throughout the brain. Tolerance: a decrease in the effectiveness of a drug that is administered repeatedly. Sensitization: an increase in the effectiveness of a drug that is administered repeatedly. Agonist says its good and helpful and antagonist it is not helpful. Antagonist: a drug that opposes or inhibits the effects of a particular neurotransmitter on the postsynaptic cell. Agonist: a drug that facilitates the effects of a particular neurotransmitter on the post synaptic cell. Drugs may exert their agonistic or antagonistic effects by influencing receptors. Direct agonist: a drug that binds with and activates a receptor. Direct antagonist: a drug that binds with a receptor but does not activate it; prevents the natural ligand from binding with the receptor. Noncompetitive binding: binding of a drug to a site on a receptor; does not interfere with the binding site for the principal ligand.
