A young man, dazed and with blood running down his face, scrambled out of the way of a volley of rocks as gunfire erupted around him.
To attend class, backpack-carrying pupils from Atuler village in Sichuan province must take on an 800m rock face, scrambling down rickety ladders and clawing their way over bare rocks as they go.
Additionally to these ROI analyses, we performed a random-effects (RFX) whole-brain analysis by computing (intact face – scrambled face) contrasts for each SF and duration (see Supplementary Data 2).
There, he took pictures of bats "roosting high up in cliff-face crevices," requiring a daring boat ride and a guano-covered cliff-face scramble; like many tales in the book, this one risks death and results in bat-related triumph.
It's not quite as easy as it sounds though - you'll need to lower yourself down vertigo-inducing cliff faces, scramble down rocky outcrops and traverse icy cold waterfalls to get to the bottom.
The ten scrambled images were modified from the selected faces, scrambled with Adobe Photoshop software using a ripple distortion filter.
In each functional run, the sequence of 'scrambled faces, faces, scrambled non-faces, non-faces' was repeated four times (in total 16 blocks and 256 images).
The localizer scan was acquired first and comprised 1 fMRI run lasting approximately 8 min. Within the run, there were 6 repetitions of the 4 experimental conditions: words, faces, scrambled words, and scrambled faces.
For the functional localizer scan, the general linear model (GLM) modeled the face, word, scrambled face or scrambled word stimuli as explanatory variables (EVs), convolved with a hemodynamic response function (HRF).
Travellers jetting off to exotic climes this winter face a scramble to get immunised against typhoid, because of a UK shortage of vaccine against the potentially fatal disease.
The resulting contrasts for each subject were transformed onto surface space, then smoothed on the surface to 5-mm FWHM, and averaged across the group to create a surface-based group map of the face versus scrambled face and word versus scrambled word contrasts.
