This substance transmits the nerve impulse to the postsynaptic fibre by diffusing across the synaptic cleft and binding to receptor molecules on the postsynaptic membrane.
These substances are transmitted as liquids, or, even more significantly, as gases, to the recipient, in which they are usually detected by olfaction or taste.
Adolescent exposure was accomplished using a social transmission of food odor paradigm in which a substance is given to one animal (demonstrator) and information about that substance is transmitted, specifically through the olfactory system, to a peer (observer) during a period of social interaction [ 1- 3].

When using gloves in the ART laboratory, toxic substances can be transmitted to culture media, even during brief contact.
Our findings suggest that whitefish embryos are largely protected by maternally transmitted substances, but build up some own innate immunocompetence several days before hatching.
Here we review our recent discovery of novel gel-microemulsions (GM) as nontoxic, dual-function intravaginal spermicides, which can be used as delivery vehicles for lipophilic drug substances targeting sexually transmitted pathogens.
He theorized that injured fish release a substance that is transmitted by smell and causes alarm.
Substance problems are transmitted to the next generation via several pathways, especially genetic disposition [ 12, 13], exposure to drugs in utero, behavioral and cognitive processes [ 14, 15].
Theories about the nature of energy as a "living force" – a physical substance that could be transmitted from one object to another – gave rise to mechanical advances like the steam engine, which in turn gave us a model for the operation of the universe.
