“…Females had stronger activation in the occipital cortex (BA17/19), and males had more extensive activation in frontal cortex, the inferior temporal gyrus (BA 37), the middle temporal gyrus (BA21), the posterior cingulate, and the amygdala. A similar pattern of gender difference for activation in emotional picture perception has been reported by others (Wrase et al, 2003;Sabatinelli et al, 2004). Comparison of the age dependent responses in our own data for the emotional pictures task shows relatively high absolute activity in the amygdala, left parahippocampal gyrus and ventral occipital cortex (BA 18,19) in the youngest group, and left inferior frontal and left temporal gyri (BA 47) in the oldest group.…”

A rapid fMRI task battery for mapping of visual, motor, cognitive, and emotional function

A set of sensory, motor, cognitive and emotional tasks were combined in a simple, rapid-presentation task battery and tested on a group of 31, normal, healthy subjects aged 22 to 76. Five tasks were selected on the basis of widespread use in fMRI and their ability to produce robust and reliable regional activations. They were: 1) a visual task designed to activate the occipital cortex; 2) a bimanual motor task designed to activate motor areas; 3) a verb generation task designed to activate speech processing areas; 4) an n-back task designed to activate areas associated with working memory and executive function; and 5) an emotional pictures task designed to provoke strong emotional responses that typically activate limbic structures. Most of the tasks produced reliable activations in individual subjects, and assessments of the distribution and reliability of individual subject activations in each targeted area are provided. The emotional pictures task did not demonstrate adequate sensitivity in a priori target regions, only in the a posteriori defined inferior temporal region. Age and gender specific differences were found in the activation patterns for both the cognitive and emotional tasks. The battery provides a prescribed means for researchers to obtain reliable functional localizers within 20-25 minutes of scanning, which can be used to support more elaborate mapping studies of brain function. The dataset can also serve as reliability metric for new fMRI labs and novice investigators seeking to test their acquisition and analysis techniques with minimal time investment and expense.

“…A recent neuroimaging study (Sabatinelli et al, 2004) showed that erotic pictures elicited a greater activity in extrastriate visual cortex in men compared with women, suggesting a male visual bias for erotic stimuli. Our findings, however, indicate a strong selectivity of ERP responses to erotic contents in women, suggesting that "erotic bias" can exist in both genders, although the extent to which it is expressed may depend on research methods, in particular their temporal and spatial resolution.…”

Rapid discrimination of visual scene content in the human brain

et al. 2006

The rapid evaluation of complex visual environments is critical for an organism's adaptation and survival. Previous studies have shown that emotionally significant visual scenes, both pleasant and unpleasant, elicit a larger late positive wave in the event-related brain potential (ERP) than emotionally neutral pictures. The purpose of the present study was to examine whether neuroelectric responses elicited by complex pictures discriminate between specific, biologically relevant contents of the visual scene and to determine how early in the picture processing this discrimination occurs. Subjects (n=264) viewed 55 color slides differing in both scene content and emotional significance. No categorical judgments or responses were required. Consistent with previous studies, we found that emotionally arousing pictures, regardless of their content, produce a larger late positive wave than neutral pictures. However, when pictures were further categorized by content, anterior ERP components in a time window between 200−600 ms following stimulus onset showed a high selectivity for pictures with erotic content compared to other pictures regardless of their emotional valence (pleasant, neutral, and unpleasant) or emotional arousal. The divergence of ERPs elicited by erotic and non-erotic contents started at 185 ms post-stimulus in the fronto-central midline regions, with a later onset in parietal regions. This rapid, selective, and content-specific processing of erotic materials and its dissociation from other pictures (including emotionally positive pictures) suggests the existence of a specialized neural network for prioritized processing of a distinct category of biologically relevant stimuli with high adaptive and evolutionary significance.

“…On the basis of previous research on gender differences in affective processing (Bellezza, Greenwald, & Banaji, 1986;Bradley, Codispoti, Sabatinelli, & Lang, 2001;Sabatinelli, Flaisch, Bradley, Fitzsimmons, & Lang, 2004;Wrase et al, 2003), and involving the IAPS in particular (Lang et al, 2008), we expected that participant gender might modulate the valence and arousal ratings. Therefore, we calculated .96], t(898) = 92.62, p < .001.…”

Introducing the Open Affective Standardized Image Set (OASIS)

We introduce the Open Affective Standardized Image Set (OASIS), an open-access online stimulus set containing 900 color images depicting a broad spectrum of themes, including humans, animals, objects, and scenes, along with normative ratings on two affective dimensions-valence (i.e., the degree of positive or negative affective response that the image evokes) and arousal (i.e., the intensity of the affective response that the image evokes). The OASIS images were collected from online sources, and valence and arousal ratings were obtained in an online study (total N = 822). The valence and arousal ratings covered much of the circumplex space and were highly reliable and consistent across gender groups. OASIS has four advantages: (a) the stimulus set contains a large number of images in four categories; (b) the data were collected in 2015, and thus OASIS features more current images and reflects more current ratings of valence and arousal than do existing stimulus sets; (c) the OASIS database affords users the ability to interactively explore images by category and ratings; and, most critically, (d) OASIS allows for free use of the images in online and offline research studies, as they are not subject to the copyright restrictions that apply to the International Affective Picture System. The OASIS images, along with normative valence and arousal ratings, are available for download from www.benedekkurdi.com/#oasis or https://db.tt/yYTZYCga.
