We tested the possibility suggested by previous imaging studies that amygdala participation in the storage of emotionally influenced memory is differentially lateralized in men and women. Male and female subjects received two PET scans for regional cerebral glucose-one while viewing a series of emotionally provocative (negative) films, and a second while viewing a series of matched, but emotionally more neutral, films. Consistent with suggestions from several previously published studies… 
Sex-related hemispheric lateralization of amygdala function in emotionally influenced memory: an FMRI investigation.
TLDR
The results provide the strongest evidence to date of a sex-related hemispheric lateralization of amygdala function in memory for emotional material and underscore the view that investigations of neural mechanisms underlying emotionally influenced memory must anticipate, and begin to account for, the apparently substantial influence of sex.
Amygdala modulation of parahippocampal and frontal regions during emotionally influenced memory storage
TLDR
Increased influences from the amygdala, presumably reflecting its memory-modulation function, occur during emotionally arousing learning situations, and these findings support the view that increased influences on other brain regions under emotional and nonemotional learning conditions are supported.
Sex differences in the neural basis of emotional memories
TLDR
Women had significantly more brain regions where activation correlated with both ongoing evaluation of emotional experience and with subsequent memory for the most emotionally arousing pictures, and greater overlap in brain regions sensitive to current emotion and contributing to subsequent memory may be a neural mechanism for emotions to enhance memory more powerfully in women than in men.
Own-sex effects in emotional memory for faces
TLDR
Functional magnetic resonance imaging results confirm the existence of sex differences in amygdala lateralization in emotional memory but also demonstrate a subtle relationship between the observer and the stimulus in this process.
Sex-related lateralized effect of emotional content on declarative memory: An event related potential study
TLDR
Data indicate that both sex and cerebral hemisphere constitute important, interacting influences on neural correlates of emotion, and of emotionally influenced memory.
Sex- and hemisphere-related influences on the neurobiology of emotionally influenced memory

TLDR
The findings presented here suggest that the interacting influences of sex and cerebral hemisphere on emotionally influenced memory are more pronounced than has been widely appreciated to date.
Boys do it the right way: Sex-dependent amygdala lateralization during face processing in adolescents
TLDR
The results indicate that adolescents display a sex-dependent lateralization of amygdala activation that is also present in basic processes of emotional perception, which suggests aSex-dependent development of human emotion processing and may further implicate possible etiological pathways for mental disorders most frequent in adolescent males.
Noradrenaline mediates amygdala activation in men and women during encoding of emotional material
TLDR
The hypothesis that the neurotransmitter noradrenaline also mediates amygdala activity in humans when processing emotional stimuli and that betablockers can disrupt the normal activation pattern in the amygdala is supported.
Sex-related differences in amygdala activity influences immediate memory
TLDR
It is shown that increased amygdala activation while viewing unpleasant pictures may preferentially facilitate immediate recognition memory in men relative to women and sex differences in amygdala activation were related to false-positive error rates in recognizing unpleasant pictures.
The effect of anticipation and the specificity of sex differences for amygdala and hippocampus function in emotional memory
TLDR
It is found that previously reported sex differences of memory associations with left amygdala for women and with right amygdala for men were confined to the ventral amygdala during picture viewing and delayed memory, and neuroanatomical evidence of sex differences for emotional memory is extended.

Event-Related Activation in the Human Amygdala Associates with Later Memory for Individual Emotional Experience
TLDR
The view that amygdala activation reflects moment-to-moment subjective emotional experience and that this activation enhances memory in relation to the emotional intensity of an experience is supported.
Involvement of the amygdala in memory storage: interaction with other brain systems.
TLDR
Findings provide strong evidence supporting the hypothesis that the amygdala is involved in modulating long-term memory storage, as well as supporting the central hypothesis guiding the research reviewed in this paper.
Amygdala activity at encoding correlated with long-term, free recall of emotional information.
TLDR
The findings support the view derived from both animal and human investigations that the AC is selectively involved with the formation of enhanced long-term memory associated with emotionally arousing events.
Hemispheric asymmetry for emotional stimuli detected with fMRI
TLDR
In a functional magnetic resonance imaging (fMRI) study, 14 female subjects viewed alternating blocks of emotionally valenced positive and negative pictures and overall brain reactivity was lateralized towards the left hemisphere for positive pictures and towards the right hemisphere for negative pictures.
fMRI identifies a network of structures correlated with retention of positive and negative emotional memory
It is likely that the encoding of emotional experiences involves a complex network of interacting brain regions. The present study used fMRI to identify brain structures involved in the encoding of
Mechanisms of emotional arousal and lasting declarative memory
TLDR
Human-subject studies confirm the prediction of animal work that the amygdala is involved with the formation of enhanced declarative memory for emotionally arousing events and suggest that the amygdaloid complex serves to influence memory-storage processes in other brain regions.
The functional neuroanatomy of emotion and affective style
TLDR
It is proposed that the PFC plays a crucial role in affective working memory and is most directly involved in the representation of elementary positive and negative emotional states while the dorsolateral PFC may be involved inThe representation of the goal states towards which these elementarypositive and negative states are directed.

Conscious and unconscious emotional learning in the human amygdala
TLDR
The results indicate that the human amygdala can discriminate between stimuli solely on the basis of their acquired behavioural significance, and second, this response is lateralized according to the subjects' level of awareness of the stimuli.

TLDR
The results suggest that trait differences in temporal pole brain-behavior relationships may relate to sex differences in verbal episodic memory.
