Ehrhardt, A.A. (1978) states that
A review of the behavioral effects of estrogen has to be divided on the basis of different time periods. During the critical phase of brain differentiation (which is species specific and takes place either before birth or neonatally), various sex hormones have long-term and permanent effects on behavior. Therefore, their action has been termed developmental or organizational. In contrast, hormones in adulthood, after the critical phase has passed, affect reversible changes in behavior and have been called activational.
An article in the Scientific American links to other several studies including Smith, C.T., et al. (2014) revealing that
greater increases in estrogen levels across the menstrual cycle led to less impulsive decision making.
whilst Kritzer, M.F. and Kohama, S.G. (1999) states that
estrogen increased dopamine innervation in the primate prefrontal cortex.
