Increasing the concentration of neurotrophin-3 in non-human primates results in changes in “positional anxiety,” the tendency to perceive many situations as threatening. UC Davis scientists initially discovered that molecular alterations occur in the dorsal amygdala of preadolescent rhesus macaques. The dorsal amygdala plays an important role in emotional responses, suggesting that the alterations might contribute to early-life anxiety. Altering the levels of neurotrophin-3 may decrease anxiety. For the millions who suffer from this debilitating condition, this news is promising.
