Pheromones For Men Factors ...

Pheromone for men odor specialists enable the insect (at least in some Lepidoptera: Boeckh et al. 1965) to discriminate pheromone molecules from other odor molecules in its environment. Molecule-bound information is decoded through the pheromone receptor sites and transferred to the cell body of the neuron as the intensity of the generator potential. The cell body transforms the information into a frequency of action potentials which is relayed via the axon to the deutocerebrum of the insect’s brain.

Pheromone quality is discriminated through the specificity of the receptor sites and the frequency of action potentials (see sect. 3.4.4). However, male pheromonal quantity is coded in the intensity of the generator potentials and the frequency of action potentials. For example, increases in pheromone concentration elicit genera- tor potentials of increased intensity and action potentials of increased frequency (Priesner, unpublished, in Boeckh et al. 1965). However, O’Connell (1972) has known more. Learn more about pheromones for men at http://pheromones-planet.com/mens-pheromones/

By comparison, Payne et al. (1970) found that antennal olfactory responsiveness of male moths to pheromone remained essentially constant to the above mentioned variables (figs. 3.6 and 3.7). Adaptation of antennal receptors lasted only seconds and could not account for the longer times of habituation. 

While environmental factors obviously affect pheromones for men perception at the behavioral level, it is apparent that the effects are mediated via neural integration beyond the peripheral receptors. Other environmental factors such as season of the year (Silverstein et al. 1968) and temperature (Vité et al. 1964) may affect male pheromone perception at the behavioral level, but they have not been investigated at the peripheral receptor level.

The perception of a single pheromone, or stimulation of a specific receptor which results in a stereotyped behavior pattern, may appear rather straight forward. When mixtures of compounds are necessary to elicit the behavioral response, the events which might take place can be more complicated male pheromones at http://www.pheromones-experts.com

In a number of different species, mostly Coleoptera, pheromone-associated in male behavior is only released in response to a mixture of naturally occurring compounds. The aggregation pheromone of the boll weevil for example, consists of four compounds (Tumlinson et al. 1969) and the aggregation behavior of various bark beetle species is mostly elicited by mixtures of pheromones and host tree terpenes (Bedard et al. 1969; Kinzer et al. 1969). In all of these cases anything less than the complete mixture results in substantial reduction or total elimination of the behav- ioral response.

Perception of attractant mixtures may result through stimulation of a common receptor. If this is the case it is unlikely that the receptor relays the same informa- lion to the central nervous system for each compound of the mixture. However, if that were so, it would be logical to expect that any one compound which stimulat- ed the receptor would elicit the given behavior, as mentioned earlier for the silk moth (Priesner 1969). Where attractant mixtures occur, stimulation of a common male pheromone.
