healthy controls using empathy for pain task. Based on our finding that the FM group did not show activation in the several pain<br />

empathy related areas during the empathy for pain task, the current study suggest that DLPFC and ACC hypoactivity in FM group is<br />

associated with a deficit in cognitive function in empathizing and evaluating other’s pain.<br />

Being in a close relationship is essential to human life. Such closeness can be described as including other in the self. To what extent<br />

does imagining a loved one differ from imagining an unfamiliar individual being in painful situations? In this functional MRI study,<br />

participants were exposed to animated stimuli depicting hands or feet in painful and non-painful situations, and instructed to imagine<br />

the scenarios perceived from three different perspectives: self, loved one and stranger. The results demonstrate that interpersonal<br />

relationships and intimacy affect top-down processing of empathy, as indicated by greater overlap between neural representations of<br />

self and other.<br />

Improved paradigms (including dual-echo EPI, spray delivered samples and an immediate swallow) and subtraction and conjunction<br />

analysis methods have been used to study the crossmodal, supra-additive response to a congruent flavour. We show the control<br />

stimulus may cancel out some cortical responses of interest, and that a conjugate analysis is advantageous to subtraction analysis,<br />

showing additional supra-additive activity in oral somatosensory areas (SII and inferior parietal areas). This supports the suggested<br />

model for flavour perception that the oral somatomotor areas play a principal role in binding taste, aroma and oral somatosensory<br />

modalities into the flavour percept.<br />

Sucrose and salt are commonly used to season foods. We investigated the brain representation of sweet and salty taste intensity using<br />

fMRI. 14 subjects visited twice and tasted a range of four solutions of either sucrose or salt (0 – 1 M). Insula activation increased with<br />

increasing concentration for both salt and sucrose. Moreover, despite similar subjective intensity ratings, insula activation by salt<br />

increased more with concentration than that by sucrose. Amygdala activation increased with increasing salt concentration only. In<br />

conclusion, sweet and salty taste intensity is represented in the insula.The greater responsiveness of the brain to saline provides<br />

supports for the idea that sensory-specific satiety may be stronger for savoury than for sweet tastes.<br />

We used an automatic camera, SenseCam, to create a recognition memory test for real-life events. Using fMRI, participants classified<br />

images as strongly or weakly remembered, strongly or weakly familiar or novel, 36 hours and 5-6 months after image acquisition. At<br />

36 hours, diverse neocortical regions were activated by recollected and familiar stimuli. There was increasing activation in right<br />

hippocampus/ posterior parahippocampal gyrus (pPHG) with increasing memory strength. Strong recollection elicited greater activity<br />

in left posterior hippocampus/pPHG than weak recollection. At 5-6 months, MTL activated for familiarity but not recollection<br />

memory. Neocortical regions were recruited for both recollection and familiarity processes.<br />
