Abstract
The neural underpinnings of social emotions such as pride and shame are largely unknown. The present study aims to add evidence by exploiting the advantage of event-related brain electrical potentials (ERP) to examine the neural processes as they unfold over time. For this purpose, a dot-estimation task was adapted to explore these emotions as elicited in a simulated social context. Pride prompted an early negativity seemingly originated in medial parietal regions (precuneus) and possibly reflecting social comparison processes in successful trials. This was followed by a late positivity originated in medial frontal regions, probably reflecting the verification of singularly successful trials. Shame, in turn, elicited an early negativity apparently originated in the cuneus, probably related to mental imagery of the social situation. It was followed by a late positivity mainly originated in the same regions as the early negativity for pride, then conceivably reflecting social comparison processes, in this occasion in unsuccessful trials. None of these fluctuations correlated with self-reported feelings of either emotion, suggesting that they instead relate to social cognitive computations necessary to achieve them. The present results provide a dynamic depiction of neural mechanisms underlying these social emotions, probing the necessity to study them using an integrated approach with different techniques.

Mechanism of Cerebralcare Granule® for Improving Cognitive Function in Resting-State Brain Functional Networks of Sub-healthy Subjects. Front Neurosci 2017; 11:410. [PMID: 28769748 PMCID: PMC5509764 DOI: 10.3389/fnins.2017.00410] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2017] [Accepted: 06/30/2017] [Indexed: 11/13/2022] Open
Abstract
Cerebralcare Granule® (CG), a Chinese herbal medicine, has been used to ameliorate cognitive impairment induced by ischemia or mental disorders. The ability of CG to improve health status and cognitive function has drawn researchers' attention, but the relevant brain circuits that underlie the ameliorative effects of CG remain unclear. The present study aimed to explore the underlying neurobiological mechanisms of CG in ameliorating cognitive function in sub-healthy subjects using resting-state functional magnetic resonance imaging (fMRI). Thirty sub-healthy participants were instructed to take one 2.5-g package of CG three times a day for 3 months. Clinical cognitive functions were assessed with the Chinese Revised Wechsler Adult Intelligence Scale (WAIS-RC) and Wechsler Memory Scale (WMS), and fMRI scans were performed at baseline and the end of intervention. Functional brain network data were analyzed by conventional network metrics (CNM) and frequent subgraph mining (FSM). Then 21 other sub-healthy participants were enrolled as a blank control group of cognitive functional. We found that administrating CG can improve the full scale of intelligence quotient (FIQ) and Memory Quotient (MQ) scores. At the same time, following CG treatment, in CG group, the topological properties of functional brain networks were altered in various frontal, temporal, occipital cortex regions, and several subcortical brain regions, including essential components of the executive attention network, the salience network, and the sensory-motor network. The nodes involved in the FSM results were largely consistent with the CNM findings, and the changes in nodal metrics correlated with improved cognitive function. These findings indicate that CG can improve sub-healthy subjects' cognitive function through altering brain functional networks. These results provide a foundation for future studies of the potential physiological mechanism of CG.
