Metacognition and sense of agency
Cognition. 2023 Sep 14;241:105622. doi: 10.1016/j.cognition.2023.105622. Online ahead of print.ABSTRACTIntelligent agents need to understand how they can change the world, and how they cannot change it, in order to make rational decisions for their forthcoming actions, and to adapt to their current environment. Previous research on the sense of agency, based largely on subjective ratings, failed to dissociate the sensitivity of sense of agency (i.e., the extent to which individual sense of agency tracks actual instrumental control over external events) from judgment criteria (i.e., the extent to which individuals self-attr...

Divergences in color perception between deep neural networks and humans
Cognition. 2023 Sep 14;241:105621. doi: 10.1016/j.cognition.2023.105621. Online ahead of print.ABSTRACTDeep neural networks (DNNs) are increasingly proposed as models of human vision, bolstered by their impressive performance on image classification and object recognition tasks. Yet, the extent to which DNNs capture fundamental aspects of human vision such as color perception remains unclear. Here, we develop novel experiments for evaluating the perceptual coherence of color embeddings in DNNs, and we assess how well these algorithms predict human color similarity judgments collected via an online survey. We find that stat...

Multiple predictions during language comprehension: Friends, foes, or indifferent companions?
Cognition. 2023 Sep 14;241:105602. doi: 10.1016/j.cognition.2023.105602. Online ahead of print.ABSTRACTTo comprehend language, we continually use prior context to pre-activate expected upcoming information, resulting in facilitated processing of incoming words that confirm these predictions. But what are the consequences of disconfirming prior predictions? To address this question, most previous studies have examined unpredictable words appearing in contexts that constrain strongly for a single continuation. However, during natural language processing, it is far more common to encounter contexts that constrain for multiple...

Sevoflurane-induced hypotension causes cognitive dysfunction and hippocampal inflammation in mice
Behav Brain Res. 2023 Sep 15;455:114672. doi: 10.1016/j.bbr.2023.114672. Online ahead of print.ABSTRACTSevoflurane commonly adopted for anesthetic in clinical practice, however, its influences on cerebral blood flow and cognitive function remain controversial. Herein, the sevoflurane-induced hypotension on arterial blood pressure, cerebral blood flow, cognitive function, and hippocampal inflammation was investigated in mice. A significant decrease in arterial blood pressure and cerebral blood flow was indicated by the sevoflurane anesthesia treatment. Moreover, sevoflurane-induced hypotension was associated with the impair...

Effect of auditory deprivation on adaptive locomotion: Interaction with lower visual field occlusion
This study aimed to investigate whether auditory deprivation affects adaptive locomotion. In particular, we aimed to elucidate the role of the auditory sense in obstacle avoidance by manipulating the visual field, which provides crucial sensory information for movement control. Sixteen participants approached a 15-cm obstacle located 6m away and stepped over it under four different conditions that combined two factors: the hearing condition controlled by wearing earmuffs with and without holes, and the lower visual field condition controlled by carrying opaque white and transparent boards. Spatiotemporal variables during t...

Nonlinear Neural Patterns Are Revealed In High Frequency Functional Near Infrared Spectroscopy Analysis
Brain Res Bull. 2023 Sep 14:110759. doi: 10.1016/j.brainresbull.2023.110759. Online ahead of print.ABSTRACTFunctional Near Infrared Spectroscopy (fNIRS) is a useful tool for measuring hemoglobin concentration. Linear theory of the hemodynamic response function supports low frequency analysis ( < 0.2 Hz). However, we hypothesized that nonlinearities, arising from the complex neurovascular interactions sustaining vasomotor tone, may be revealed in higher frequency components of fNIRS signals. To test this hypothesis, we simulated nonlinear hemodynamic models to explore how blood flow autoregulation changes may alter evoke...

Chronic memantine disrupts spatial memory and up-regulates Htr1a gene expression in the hippocampus of GPR39 (zinc-sensing receptor) KO male mice
We report: no effects of acute memantine on ELM; a tendency to improve the "where?" component of ELM in both WT and GPR39 KO mice following 12 days of memantine; and, a disruption of SM in GPR39KO mice after 24 days of memantine treatment. The latter result was associated with upregulation of Htr1a hippocampal expression.PMID:37716463 | DOI:10.1016/j.brainres.2023.148577
