Revealing the Mechanisms of Semantic Satiation with Deep Learning Models

Revealing the Mechanisms of Semantic Satiation with Deep Learning Models

Deep Learning Model Reveals Mechanisms of Semantic Satiation Semantic satiation, the phenomenon where a word or phrase loses its meaning after being repeated many times, is a well-known psychological phenomenon. However, the micro-neural computational principles underlying this mechanism remain unknown. This paper uses a continuous coupled neural n...

Electrophysiological Signatures of Veridical Head Direction in Humans

Electrophysiological Signatures of Veridical Head Direction in Humans

Electrophysiological Signatures of Veridical Head Direction in Humans Navigation is one of the core components of human complex cognition, where head direction information is crucial for positioning oneself in space. However, due to the requirement of having the head fixed in a specific position during most neuroimaging experiments, understanding h...

Ventral Subiculum Promotes Wakefulness Through Several Pathways in Male Mice

The Ventral Subiculum Promotes Wakefulness Through Multiple Pathways in Male Mice Background The ventral subiculum (vsub) is a major output region of the hippocampus, playing a crucial role in motivation, stress integration, and anxiety-like behavior, all of which depend on a high state of wakefulness. However, the role of vsub in wakefulness and i...

Differential Cortical Layer Engagement During Seizure Initiation and Spread in Humans

Differential Cortical Layer Engagement During Seizure Initiation and Spread in Humans

Study on the Differences in Cortical Layers During Epileptic Seizure Onset and Spread Epilepsy is a neurological disorder that severely impacts patients’ quality of life, affecting approximately 1% of the global population. Among all epilepsy patients, nearly one-third are resistant to pharmaceutical treatments, known as drug-resistant epilepsy. Fo...

Cortex-wide Topography of 1/f-exponent in Parkinson’s Disease

Cortex-wide Topography of 1/f-exponent in Parkinson’s Disease

Topographical Map of the 1/f Index in the Whole Brain for Parkinson’s Disease Authors: Pascal Helson, Daniel Lundqvist, Per Svenningsson, Mikkel C. Vinding, Arvind Kumar Research Background Parkinson’s Disease (PD) is a progressive and debilitating brain disorder primarily characterized by motor dysfunction but also affecting perceptual and cogniti...

Modulating the Difficulty of a Visual Oddball-like Task and P3m Amplitude

Modulation of P3m Amplitude by Task Difficulty in a Visual Oddball Task Background In cognitive neuroscience research, Event-Related Potentials (ERP) and Event-Related Fields (ERF) are important means to explore the cognitive processing mechanisms of the brain. Among these, the P3 component (referred to as P3m in magnetoencephalography) has garnere...

Neurophysiological Study of Orientation Discrimination in a Working Memory Task

Neurophysiological Study: Neurophysiological Research on Orientation Discrimination in a Working Memory Task Background Recognizing and remembering the spatial orientation of the environment is a crucial component of visuospatial behavior. Accurately storing and recalling this information helps us navigate in space and respond adaptively to rapid c...

Theta Oscillations Support Prefrontal-Hippocampal Interactions in Sequential Working Memory

Study on Theta Oscillations in Hippocampus-Prefrontal Interaction Supporting Sequential Working Memory Academic Background The dorsolateral prefrontal cortex (DLPFC) and the hippocampus play crucial roles in sequential working memory, but the specific interaction mechanisms are not yet clear. Previous studies have shown that these two brain regions...

Study on Different Brain Activation Rearrangement during Cognitive Workload from ERD/ERS and Coherence Analysis

Study on Different Brain Activation Reorganization during Cognitive Load: ERD/ERS and Coherence Analysis Academic Background When humans engage in imagination, movement, or cognitive tasks, their brain functional activity patterns and activated regions differ. These pattern changes are also reflected in changes in brain electrical activity, which c...

Speech-Induced Suppression During Natural Dialogues

During human communication, the brain processes self-generated speech and others’ speech differently, a phenomenon known as the Speech-Induced Suppression (SIS) mechanism. This mechanism involves the motor efference copy in the perception pathway, functioning similar to an “echo” that helps filter internally generated signals to avoid confusing the...
