“…For one, many of these studies did not have adequate coverage of the hippocampus (Casey et al, 2001;Kirino et al, 2000;McCarthy et al, 1997;Menon et al, 1997). Neuroimaging studies, which have scanned the whole brain, may also have failed to detect hippocampal activation (Ardekani et al, 2002;Downar et al, 2002;Higashima et al, 1996;Horn et al, 2003;Linden et al, 1999;Opitz et al, 1999) due to susceptibility artifacts in this region (Veltman et al, 2000). These artifacts result from abrupt changes in magnetic susceptibility that occurs across tissue interfaces such as the border between air-filled sinuses and brain parenchyma or between bone and brain parenchyma.…”

“…A number of neuroimaging studies have examined brain responses to the oddball task; these studies have provided evidence for the involvement of largescale distributed network involving mainly the dorsolateral prefrontal cortex, anterior cingulate cortex, and the posterior parietal cortex (Ardekani et al, 2002;Casey et al, 2001;Downar et al, 2002;Higashima et al, 1996;Horn et al, 2003;Kiehl et al, 2001;Kirino et al, 2000;Linden et al, 1999;McCarthy et al, 1997;Menon et al, 1997;Opitz et al, 1999;Stevens et al, 2000;Yoshiura et al, 1999). Only two of these studies have reported responses in medial temporal lobe regions.…”

Hippocampal involvement in detection of deviant auditory and visual stimuli

Recent models of hippocampal function have emphasized its role in processing sequences of events. In this study, we used an oddball task to investigate hippocampal responses to the detection of deviant "target" stimuli that were embedded in a sequence of repetitive "standard" stimuli. Evidence from intracranial event-related potential studies has suggested a critical role for the hippocampus in oddball tasks. However, functional neuroimaging experiments have failed to detect activation in the hippocampus in response to deviant stimuli. Our study aimed to resolve this discrepancy by using a novel functional magnetic resonance imaging (fMRI) technique that drastically improves signal detection in the hippocampus. Significant hippocampal activation was observed during both auditory and visual oddball tasks. Although there was no difference in the overall level of hippocampal activation in the two modalities, significant modality differences in the profile of activation along the long axis of the hippocampus were observed. In both left and right hippocampi, an anterior-to-posterior gradient in the activation (anterior to posterior) was observed during the auditory oddball task, whereas a posterior-to-anterior gradient (posterior to anterior) was observed during the visual oddball task. These results indicate that the hippocampus is involved in the detection of deviant stimuli regardless of stimulus modality, and that there are prominent modality differences along the long axis of the hippocampus. The implications of our findings for understanding hippocampal involvement in processing sequences of events are discussed.

“…On the other hand, P3 latency is considered a measure of stimulus evaluation speed and has been associated with mental processing speed (for review, see Linden 2005;Polich 2007). Research has linked a broad network of brain regions to the P3 generation (Horn et al 2003;Linden 2005) and there is evidence that P3 components reflect indirect modulating effects from dopamine, acetylcholine, noradrenaline, or serotonin neuromodulators (Hansenne 2000;Polich and Criado 2006).…”

“…This view is supported by the observed activation in right IFG (BA 44), left IFG (BA 45), and ACC also only by motion standstill. Taken together, by motion standstill we observed activation of a typical attention network [see Corbetta and Shulman, 2002 Furthermore, this network is also activated by visual [Kirino et al, 2000;Linden et al, 1999] and acoustic [Horn et al, 2003] target detection paradigms. Therefore, the r-IPL posterior can be regarded as a multimodal area, an area activated together with the anterior attentional network by orienting reaction towards unresolved or target stimuli.…”

Previous studies on motion perception revealed motion-processing brain areas sensitive to changes in luminance and texture (low-level) and changes in salience (high-level). The present functional magnetic resonance imaging (fMRI) study focused on motion standstill. This phenomenon, occurring at fast presentation frequencies of visual moving objects that are perceived as static, has not been previously explored by neuroimaging techniques. Thirteen subjects were investigated while perceiving apparent motion at 4 Hz, at 30 Hz (motion standstill), isoluminant static and flickering stimuli, fixation cross, and blank screen, presented randomly and balanced for rapid event-related fMRI design. Blood oxygenation level-dependent (BOLD) signal in the occipito-temporal brain region MT/V5 increased during apparent motion perception. Here we could demonstrate that brain areas like the posterior part of the right inferior parietal lobule (IPL) demonstrated higher BOLD-signal during motion standstill. These findings suggest that the activation of higher-order motion areas is elicited by apparent motion at high presentation rates (motion standstill). We interpret this observation as a manifestation of an orienting reaction in IPL towards stimulus motion that might be detected but not resolved by other motion-processing areas (i.e., MT/V5).
