“…Particularly, neural responses in a more posterior part of the hippocampus might indicate the encoding of emotionally negative memories (Shafer & Dolcos, 2012), whereas the anterior cluster might process gist-like associations between a threat (painful stimulation) and its context (Poppenk et al, 2013). Our PPI analyses show significant connections of the more posterior part of the hippocampus with the posterior cingulate cortex/ thalamus and precuneus (BA 7a), regions that have been shown to display increased responses in a recognition memory task under conditions of high arousal (Greene, Flannery, & Soto, 2014). Moreover, the functional connections between both hippocampal clusters might involve the integration of their respective computations while the correlation of the aHPC and amygdala possibly reflects the projection of the contextual representation to the amygdala to generate a fear response (although the PPI method does not permit directional statements).…”

Contextual fear conditioning studies in animals and humans found an involvement of the hippocampus and amygdala during fear learning. To exclude a focus on elements of the context we employed a paradigm, which uses two feature-identical contexts that only differ in the arrangement of the features and requires configural processing. We employed functional magnetic resonance imaging to determine the role of the hippocampus and neocortical areas during the acquisition of contextual fear in humans. For contextual fear acquisition, we paired one context (CS+) with an aversive electrical stimulus, whereas the other (CS-) was never followed by aversive stimulation. Blood oxygen level dependent activation to the CS+ was present in the insula, inferior frontal gyrus, inferior parietal lobule, superior medial gyrus and caudate nucleus. Furthermore, the amygdala and hippocampus were involved in a time-dependent manner. Psychophysiological interaction analyses revealed functional connectivity of a more posterior hippocampal seed region with the anterior hippocampus, posterior cingulate cortex and superior parietal lobule. The anterior hippocampus was functionally coupled with the amygdala and postcentral gyrus. This study complements previous findings in contextual fear conditioning in humans and provides a paradigm which might be useful for studying patients with hippocampal impairment.

“…1 Rendering of the three interiors that were used as stimuli, counterbalanced across subjects. Each subject was placed in the middle of the room during the experiment Finally, the activity in parietal sites related to pleasantness could reflect the participation in perception of goal-directed hand actions (Salmi et al 2014) as well as a manifestation of positive moods (Greene et al 2014).…”

Neurophysiological correlates of embodiment and motivational factors during the perception of virtual architectural environments

et al. 2015

The recent efforts aimed at providing neuroscientific explanations of how people perceive and experience architectural environments have largely justified the initial belief in the value of neuroscience for architecture. However, a systematic development of a coherent theoretical and experimental framework is missing. To investigate the neurophysiological reactions related to the appreciation of ambiances, we recorded the electroencephalographic (EEG) signals in an immersive virtual reality during the appreciation of interior designs. Such data have been analyzed according to the working hypothesis that appreciated environments involve embodied simulation mechanisms and circuits mediating approaching stimuli. EEG recordings of 12 healthy subjects have been performed during the perception of three-dimensional interiors that have been simulated in a CAVE system and judged according to dimensions of familiarity, novelty, comfort, pleasantness, arousal and presence. A correlation analysis on personal judgments returned that scores of novelty, pleasantness and comfort are positively correlated, while familiarity and novelty are in negative way. Statistical spectral maps reveal that pleasant, novel and comfortable interiors produce a de-synchronization of the mu rhythm over left sensorimotor areas. Interiors judged more pleasant and less familiar generate an activation of left frontal areas (theta and alpha bands), along an involvement of areas devoted to spatial navigation. An increase in comfort returns an enhancement of the theta frontal midline activity. Cerebral activations underlying appreciation of architecture could involve different mechanisms regulating corporeal, emotional and cognitive reactions. Therefore, it might be suggested that people's experience of architectural environments is intrinsically structured by the possibilities for action.

“…This is mainly because 1st) the Cz electrode site is positioned right over the central portion of the precentral gyrus; an area that is primarily responsible for the control of lower limbs (Jain et al, 2013), and 2nd) fronto‐parietal connectivity is generally associated with goal‐directed attention and sensorimotor representations guiding body‐environment interactions (Spadone et al, 2021). In addition, several areas of the parietal cortex are implicated with sensory processing, behavioral control, and arousal regulation (e.g., Acevedo et al, 2014; Greene et al, 2014).…”

The main objective of this study was to further understanding of the patterns of spectral connectivity during exercise in low‐ and high‐tolerant individuals. Thirty‐nine healthy individuals (i.e., 17 low‐ and 22 high‐tolerant participants) took part in the present study. A state‐of‐the‐art portable electroencephalography system was used to measure the brain's electrical activity during an incremental exercise test performed until the point of volitional exhaustion on a cycle ergometer. Spectral coherence was used to explore the patterns of connectivity in the frontal, central, and parietal regions of the brain. Physiological, perceptual, and affective responses were assessed throughout the exercise bout. The spontaneous eyeblink rate was also calculated prior to commencement and upon completion of the exercise trial as an indirect assessment of the dopaminergic system. The present findings indicate that high‐tolerant individuals reported lower levels of perceived activation, especially during the preliminary stages of the exercise test. Participants in the high‐tolerance group also reported greater levels of remembered pleasure upon completion of the exercise test. The data also revealed that high‐tolerant individuals exhibited increased connectivity of theta waves between frontal, central, and parietal electrode sites and increased connectivity of beta waves, primarily within the parietal cortex. Correlational analysis indicated the possibility that low‐ and high‐tolerant individuals make use of different neural networks to process and regulate their psychophysiological state during exercise‐related situations. This strategy could potentially represent a conscious decision to downregulate affective arousal and facilitate the neural control of working muscles during situations of physical stress.
