with the Changing of the seasons
Most of us take seasonal changes in mood for granted. According to a new study
the cause may be the seasons tinkering with chemicals in our brain. As reported
(prep.) the november 3 journal of neuroscience, researchers found the evidence of
seasonal differences in dopamine, a chemical messenger involved in motivation
pleasure movement and learning Using brain scans, psychiatrist, daniel eisenberg and
his colleagues measure dopamine levels (prep.)the brains of 86 healthy people at
different times of the year People scan in the fall and winter had an average
dopamine signal 4.3 percent greater than those scan in the spring and summer in an
area that receive messages (prep.) dopamine-carrying neurons. eisenberg says future
work will have to test whether dopamine levels in individual fluctuate with the
seasons in the same way or if this result reflect some other differences unrelated to
season between the groups, which were similar in age sex ethnicity. If the pattern
hold, it mean environmental cues that change seasonally, such as the amount (prep.)
sunlight we see, may actually mold our brain state. eisenberg says that this type of
dopamine fluctuation could contribute to the winter laziness and summertime energy
that we all experience.
