Cahill, L. Cards drawn from each of 4 decks of the reward IGT and from each of the decks of punishment IGT served as a variable for deck-wise analysis. Men with damage to the left amygdala and women with damage to the right amygdala were relatively unimpaired.
Nevertheless, there is a growing body of evidence that several key neural correlates of emotion and decision-making show sex-related variations in functional lateralization. Sex-related hemispheric lateralization of amygdala function in emotionally influenced memory: an FMRI investigation.
Through molecular, animal, and neuroimaging studies, a great deal of information regarding the differences between male and female brains and how much they differ in regards to both structure and function has been uncovered. Visualizing sexual dimorphism in the brain.
Hemiplegia of early onset and the faculty of speech with special reference to hemispherectomy. Third, a question could be raised as to whether our findings reflect response to fluoxetine or a nonspecific placebo response? The mean age of the healthy women was Patients were excluded for any of the following reasons: serious suicide risk, substance abuse disorders including alcohol abuse within the last 6 months, psychotic disorders, antisocial personality disorder, seizure disorder, organic mental disorder, history of head trauma, or other neurological disorder.
Bradshaw, J. One form of depression among women, which responds to an SSRI antidepressant, may be characterized by relatively greater activation of these left-hemisphere regions. Download citation.
If a split-brain patient focuses brain sex differences hemispheric specialization and listening in Fleetwood vision on the center of a screen, anything to the left of the focal point left visual field goes to the right hemisphere, while anything in the right visual field goes to the left hemisphere.
J Abnorm Psychol 98 : — What might account for the finding of responder vs nonresponder differences on the verbal test in women, but the nonverbal test in men? Predictors of drug response in depression. Hemispheric superiority in reaction time to faces: a sex difference.

London: Penguin; Christman, S. External link. Table 1 Demographic data corresponding to males M and females F and imaging parameters Tp: time points and TR: repetition time for all data sets from 19 research sites.
Regions with high functional connectivity may play an important role for the optimal efficiency and integration of functional networks both at rest and during task conditions Biswal et al. In the punishment decks, both males and females differentiated between the 4 decks; however, only males seemed to benefit from valence-directed instructions.
