This presentation summarizes the latest findings from Cognitive Neuroscience as pertains to Attachment theory, with an emphasis on the literature from 2012 to 2014. It then explores the linkages in the neuroscience literature between attachment theory and mentalization, particularly in the areas of cognitive and emotional mentalization. Implications of the findings are considered, with an emphasis on the application of the findings for emotional regulation in the life of the counselor as well as for psychological and spiritual intervention in the lives of the counselee.
The Concept Of Qailulah (Midday Napping) From Neuroscientific And Islamic Perspectives, Mohd Amzari Tumiran
The Concept Of Qailulah (Midday Napping) From Neuroscientific And Islamic Perspectives, Mohd Amzari Tumiran
Mohd Amzari Tumiran
Napping/siesta during the day is a phenomenon which is widely practised in the world. However, the timing, frequency and duration may vary. The basis of napping is also diverse, but it is mainly done for improvement of alertness and general well-being. Neuroscience reveals that midday napping improves memory, enhances alertness, boosts wakefulness and performance, and recovers certain qualities of lost night sleep. Interestingly, Islam, the religion of the Muslims, advocates midday napping primarily because it was a practice preferred by Prophet Muhammad (pbuh). The objectives of this review are to investigate and compare identical key points on focused topic from …
Senile Dementia From Neuroscientific And Islamic Perspectives, Mohd Amzari Tumiran
Senile Dementia From Neuroscientific And Islamic Perspectives, Mohd Amzari Tumiran
Mohd Amzari Tumiran
Diseases involving the nervous system drastically change lives of victims and commonly increase dependency on others. This paper focuses on Senile Dementia (SD) from both the neuroscientific and Islamic perspectives, with special emphasis on the integration of ideas between the two different disciplines. This would enable effective implementation of strategies to address issues involving this disease across different cultures, especially among the world-wide Muslim communities. In addition, certain incongruence ideas on similar issues can be understood better. The former perspective is molded according to conventional modern science while the latter on the analysis of various texts including the holy Qur’an, …
Social Habituation And Dishabituation In Cd-1 Mice Treated With The Norepinephrine Neurotoxin N-(2-Chloroethyl)-N-Ethyl-2-Bromobenzylamine (Dsp-4), Hewlet Mcfarlane
Social Habituation And Dishabituation In Cd-1 Mice Treated With The Norepinephrine Neurotoxin N-(2-Chloroethyl)-N-Ethyl-2-Bromobenzylamine (Dsp-4), Hewlet Mcfarlane
Hewlet McFarlane
Male CD-1 mice between postnatal days 60 and 90 were injected intraperitoneally (i.p) with either water vehicle (controls) or 50$\mu$g/g of the norepinephrine neurotoxin N-(2-chloroethyl)-N-ethyl-2-bromobenzylamine (DSP-4). They were tested 3 to 6 days later on the odors of adult males in a four-trial habituation/dishabituation paradigm. There were four groups: group CSS were water injected and exposed to the same male on all four trials; group CSN were water injected and exposed to the same male on the first three trials and a novel one on the fourth; group DSN were DSP-4 treated and exposed the same male on the first …
Probabilistic Atlases For Face And Biological Motion Perception: An Analysis Of Their Reliability And Overlap, Andrew Engell
Probabilistic Atlases For Face And Biological Motion Perception: An Analysis Of Their Reliability And Overlap, Andrew Engell
Andrew Engell
Neuroimaging research has identified several category-selective regions in visual cortex that respond most strongly when viewing an exemplar image from a preferred category, such as faces. Recent studies, however, have suggested a more complex pattern of activation that has been heretofore unrecognized, e.g., the presence of additional patches of activation to faces beyond the well-studied fusiform face area, and the activation of ostensible face selective regions by animate motion of non-biological forms. Here, we characterize the spatial pattern of brain activity evoked by viewing faces or biological motion in large fMRI samples (N > 120). We create probabilistic atlases for both …
Common Neural Mechanisms For The Evaluation Of Facial Trustworthiness And Emotional Expressions As Revealed By Behavioral Adaptation, Andrew Engell
Common Neural Mechanisms For The Evaluation Of Facial Trustworthiness And Emotional Expressions As Revealed By Behavioral Adaptation, Andrew Engell
Andrew Engell
People rapidly and automatically evaluate faces along many social dimensions. Here,we focus on judgments of trustworthiness, which approximate basic valence evaluation of faces, and test whether these judgments are an overgeneralization of the perception of emotional expressions. We used a behavioral adaptation paradigm to investigate whether the previously noted perceptual similarities between trustworthiness and emotional expressions of anger and happiness extend to their underlying neural representations. We found that adapting to angry or happy facial expressions causes trustworthiness evaluations of subsequently rated neutral faces to increase or decrease, respectively. Further, we found no such modulation of trustworthiness evaluations after participants …
Differential Activation Of Frontoparietal Attention Networks By Social And Symbolic Spatial Cues, Andrew Engell
Differential Activation Of Frontoparietal Attention Networks By Social And Symbolic Spatial Cues, Andrew Engell
Andrew Engell
Perception of both gaze-direction and symbolic directional cues (e.g. arrows) orient an observer’s attention toward the indicated location. It is unclear, however, whether these similar behavioral effects are examples of the same attentional phenomenon and, therefore, subserved by the same neural substrate. It has been proposed that gaze, given its evolutionary significance, constitutes a ‘special’ category of spatial cue. As such, it is predicted that the neural systems supporting spatial reorienting will be different for gaze than for non-biological symbols. We tested this prediction using functional magnetic resonance imaging to measure the brain’s response during target localization in which laterally …
The Fmri Bold Signal Tracks Electrophysiological Spectral Perturbations, Not Event-Related Potentials., Andrew Engell
The Fmri Bold Signal Tracks Electrophysiological Spectral Perturbations, Not Event-Related Potentials., Andrew Engell
Andrew Engell
Functional magnetic resonance imaging (fMRI) and electroencephalography (EEG) are primary tools of the psychological neurosciences. It is therefore important to understand the relationship between hemodynamic and electrophysiological responses. An early study by Huettel and colleagues found that the coupling of fMRI blood-oxygen-level-dependent signal (BOLD) and subdurally-recorded signal-averaged event-related potentials (ERPs) was not consistent across brain regions. Instead, a growing body of evidence now indicates that hemodynamic changes measured by fMRI reflect non-phase-locked changes in high frequency power rather than the phase-locked ERP. Here, we revisit the data from Huettel and colleagues and measure event-related spectral perturbations (ERSPs) to examine the …
Face, Eye, And Body Selective Responses In Fusiform Gyrus And Adjacent Cortex: An Intracranial Eeg Study., Andrew D. Engell, Gregory Mccarthy
Face, Eye, And Body Selective Responses In Fusiform Gyrus And Adjacent Cortex: An Intracranial Eeg Study., Andrew D. Engell, Gregory Mccarthy
Andrew D. Engell
unctional MRI (fMRI) studies have investigated the degree to which processing of whole faces, face-parts, and bodies are differentially localized within the fusiform gyrus and adjacent ventral occipitotemporal cortex. While some studies have emphasized the spatial differentiation of processing into discrete areas, others have emphasized the overlap of processing and the importance of distributed patterns of activity. Intracranial EEG (iEEG) recorded from subdural electrodes provides excellent temporal and spatial resolution of local neural activity, and thus provides an alternative method to fMRI for studying differences and commonalities in face and body processing. In this study we recorded iEEG from 12 …
Selective Attention Modulates Face-Specific Induced Gamma Oscillations Recorded From Ventral Occipitotemporal Cortex, Andrew Engell
Selective Attention Modulates Face-Specific Induced Gamma Oscillations Recorded From Ventral Occipitotemporal Cortex, Andrew Engell
Andrew Engell
EEG studies from subdural electrodes have demonstrated a face-specific event-related potential (face-N200) recorded from human ventral occipitotemporal cortex. The insensitivity of face-N200 to task manipulations has supported the proposal that face-N200 reflects an initial obligatory response to faces. This result stands in striking contrast to results of neuroimaging studies that have demonstrated strong task sensitivity of the fusiform hemodynamic response evoked by faces, and thus has created a paradox in the face perception literature. We recorded field potentials directly from the cortical surface of 16 patients while they selectively attended to faces or houses. Here we report that face-specific gamma …
Facial Expression And Gaze-Direction In Human Superior Temporal Sulcus, Andrew Engell
Facial Expression And Gaze-Direction In Human Superior Temporal Sulcus, Andrew Engell
Andrew Engell
The perception of facial expression and gaze-direction are important aspects of non-verbal communication. Expressions communicate the internal emotional state of others while gaze-direction offers clues to their attentional focus and future intentions. Cortical regions in the superior temporal sulcus(STS) play a central role in the perception of expression and gaze, but the extent to which the neural representations of these facial gestures are overlapping is unknown. In the current study 12 subjects observed neutral faces with direct-gaze, neutral faces with averted-gaze, or emotionally expressive faces with direct-gaze while we scanned their brains with functional magnetic resonance imaging (fMRI), allowing a …
Implicit Trustworthiness Decisions: Automatic Coding Of Face Properties In Human Amygdala, Andrew Engell
Implicit Trustworthiness Decisions: Automatic Coding Of Face Properties In Human Amygdala, Andrew Engell
Andrew Engell
Deciding whether an unfamiliar person is trustworthy is one of the most important decisions in social environments. We used functional magnetic resonance imaging to show that the amygdala is involved in implicit evaluations of trustworthiness of faces, consistent with prior findings. The amygdala response increased as perceived trustworthiness decreased in a task that did not demand person evaluation. More importantly, we tested whether this response is due to an individual’s idiosyncratic perception or to face properties that are perceived as untrustworthy across individuals. The amygdala response was better predicted by consensus ratings of trustworthiness than by an individual’s own judgments. …

Polychlorinated Biphenyl Exposure Alters Oxytocin Receptor Gene Expression And Maternal Behavior In Rat, Howard Cromwell
Polychlorinated Biphenyl Exposure Alters Oxytocin Receptor Gene Expression And Maternal Behavior In Rat, Howard Cromwell
Howard Casey Cromwell
Polychlorinated biphenyl (PCB) is a persistent organic pollutant known to induce diverse molecular and behavioral alterations. Effects of PCB exposure could be transmitted to future generations via changes in behavior and gene expression. Previous work has shown that PCB-exposure can alter social behavior. The present study extends this work by examining a possible molecular mechanism for these changes. Pregnant rats (Sprague-Dawley) were exposed through diet to a combination of non-coplanar (PCB 47 - 2,20,4,40-tetrachlorobiphenyl) and coplanar (PCB 77 - 3,30,4,40- tetrachlorobiphenyl) congeners. Maternal care behaviors were examined by evaluating the rate and quality of nest building on the last 4 …
