Fig. 3A shows a plot of the average actual and ideal WHRs of male and female observers.

<p>Males appear to prefer a more tubular shape in their lower torso (as indexed by a higher WHR) as their ideal. In comparison, females appear to desire a curvier lower torso shape (with a lower WHR values) for their ideal. <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0050601#pone-0050601-g003" target="_blank">Fig. 3B</a> shows an equivalent plot for WCR. Both male and female participants preferred a lower WCR (more curvaceous) in their ideal than they actually possessed.</p

Plots of the width of the right side of the torso, starting from the midline, for the average male and female bodies at five different BMI levels.

<p>The plots illustrate that increasing BMI is associated not only with a generalized increase in torso width, reflected by the systematic separation of one profile from the next, but also with a non-linear component to the change in body shape. This non-linear component is illustrated by the male torso outline in sub-regions A (near the waist) and B (the lower hip). In region A, as BMI increases from 15 to 35, the contour of the waist changes from convex to concave and in region B, the slope of the line from lower to higher hip slices becomes less and less steep. There are similar non-linear shape changes in the female torso in sub-regions C (the upper chest) and D (upper hip).</p

Table 1 summarises the anthropometric measures taken from the male and female bodies in this study.

Time-frequency plots for each cortical site (ATL, FG, and CS) are presented in each column.

<p>(A) Main effect of specificity. (B) Main effect of category. In both (A) and (B), the first and second row report the percentage signal change in total power for each condition, relative to their passive periods. The third row shows differences between the two conditions. The black lines in the time-frequency plots indicate regions showing significant differences between the two conditions (p < .05). See text for details.</p

3D rendered cortical representations showing significant activity above baseline across conditions, during 500 ms post-target onset in four frequency bands (15–25 Hz, 25–35 Hz and 35–50 Hz).

<p>t-Maps are thresholded at p<0.01 (corrected). All the activations represent event related desynchronization. Significant event related desynchronization was only observed between 5–15 Hz in a region of the right fusiform gyrus that overlapped with the activity observed at 15-25Hz, at a reduced threshold (p = 0.05) and thus this frequency band was omitted from this figure, although all of the whole-brain maps can be accessed from Neurovault (<a href="http://neurovault.org/collections/1937/" target="_blank">http://neurovault.org/collections/1937/</a>). Arrows indicate the locations selected for the VE analysis.</p

Shows time frequency plots for all four ROIs for all participants' responses to words.

<p>The left column represents evoked activity, the middle column presents evoked plus induced activity, while the right column represents induced activity alone.</p

Temporal evolution of left hemisphere and ventral brain activity elicited by written words, consonant string, and faces.

<p>The figure shows the beamformer group analysis of brain activity in the beta frequency band for successive 200 ms long windows of interest, each separated in time by 50 ms, and superimposed on a canonical brain with the cerebellum removed.</p

The upper row shows the time-frequency plots for words, consonant strings, and faces for the left IFG ROI.

<p>The lower row shows the differences between the time-frequency plots comparing words with consonants strings and words with faces. The white dotted lines represent regions in the time-frequency plots within which the difference between conditions reached significance at p<0.05, according to the general linear mixed models.</p

Significant differences between viewing infant and adult faces.

<p>The group SAM analysis revealed a significant peak in the medial orbitofrontal cortex in the 10–30 Hz band in the 0–250 ms (first two columns), 100–350 ms (third column) and 200–450 ms (fourth column) windows when participants viewed infant (upper row) and not when they viewed adult faces (lower row). The fifth column shows the integrated z-map over the three time windows (with Z>3.1) with all active brain regions listed in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0001664#pone-0001664-t001" target="_blank">Table 1</a>. In order to see the extent of the spread of activity over the fusiform cortices elicited by faces, the group activity is superimposed on a ventral view of the human brain (with the cerebellum removed).</p

Comparing the power changes in activity for infant vs adult faces.

<p>Significant differences in power changes in activity were found first in the medial OFC and then in the right FFA. A) In the medial OFC the first significant peak (p<0.001) in differences in power between infant and adult faces in the 10–15 Hz band was found at around 130 ms. These early differences were not found in the FFA. B) In contrast, differences in power were found later, at around 165 ms, in a different band (20–25 Hz) in the right FFA.</p
