The bird enjoys the song of a suitable groom, and there is a certain neurotransmitter in the background

The best concert engages the female brain in two ways.

At the spring singing concerts, the bird dogs chirp to the best of their ability. Females compare performances and choose brain chemicals from the groom candidate.

Whenever a liverworm meets the female’s wishes, dopamine floods its brain. It is a mediator of the central nervous system and is known to promote motivation and learning.

Dopamine produced by certain midbrain cells, and apparently the substance binds two different pathways from the female to the song at the same time.

It increases the alertness of the auditory cortex and awakens the nucleus, which produces rewarding sensations.

The latter effect has been considered the most important for the bird. Namely, when dopamine acts on a similar nucleus at the prairie mole, it causes them to bind to their life partner.

However, one of the routes also motivates the bird so strongly that it alone changes behavior.

If dopamine is added artificially to the auditory cortex, even a poor song can excite a female, Canadian researchers say Current Biology magazine.

Reminiscent of a person’s enjoyment of music

In the study, zebrafish females were given recordings of songs from different dogs.

The songs were presented to the females two at a time so that the female could choose the song she was listening to by twitching the string. Preference was inferred from which rope the female tore more often in two hours.

Once the favorites were identified, a dopamine-like drug was administered to the auditory cortex of some females while playing an unpleasant song.

Its becoming more pleasing was seen when the string test was repeated.

It can be assumed that the female bird experiences the feeling produced by the favorite song as strong. After all, it is a matter of choosing the father of the chicks, for which evolution has certainly produced a strong motivation.

Even in us humans, the enjoyment of music is linked to the regulation of dopamine in the brain, even though the taste for music does not primarily determine pairing for us.

An international team of researchers reported in 2019 Pnasthat dopamine levels can alter the emotions evoked by different bodies in a subject.
