Although recent work has made headway in understanding the neural temporospatial dynamics of conscious perception, much that focused on visual paradigms. To determine whether there are shared mechanisms for perceptual consciousness across sensory modalities, here we test within auditory domain. Participants completed an threshold task while undergoing intracranial electroencephalography. Recordings from >2,800 grey matter electrodes were analyzed broadband gamma power (a range which reflects local activity). For perceived trials, find nearly simultaneous activity early regions, right caudal middle frontal gyrus, and non-auditory thalamus; followed by a wave sweeps through association regions into parietal cortices. not significant is restricted to regions. These findings show cortical subcortical networks involved perception similar those observed with vision, suggesting perception.

Determining the level of consciousness in patients with brain injury-and more fundamentally, establishing what they can experience-is ethically and clinically impactful. Patient behaviors may unreliably reflect their consciousness: a subset unresponsive demonstrate covert by willfully modulating activity to commands through fMRI or EEG. However, current paradigms for assessing remain fundamentally limited because are insensitive, rely on imperfect assumptions functional neuroanatomy, do not spectrum conscious experience. Neural decoding, which stimuli concepts reconstructed from activity, offers novel approach assessment that overcomes many these limitations. In this article, we discuss state assessments, shortcomings, science neural potential application decoding disorders consciousness, future directions help realize potential. To so, searched PubMed Google Scholar databases pertinent articles published between January 1990 September 2024, using search terms "covert consciousness," "cognitive motor dissociation," "neural decoding," "semantic decoding." Redefining improve sensitivity, enhance granularity, directly address question experience after injury.

Recent advances in machine learning have led to revolutionary breakthroughs computer games, image and natural language understanding, scientific discovery. Foundation models large-scale (LLMs) recently achieved human-like intelligence thanks BigData. With the help of self-supervised (SSL) transfer learning, these may potentially reshape landscapes neuroscience research make a significant impact on future. Here we present mini-review recent foundation generative AI as well their applications neuroscience, including speech, semantic memory, brain-machine interfaces (BMIs), data augmentation. We argue that this paradigm-shift framework will open new avenues for many directions discuss accompanying challenges opportunities.

This paper explores the relation between within-person and between-person research designs using concept of ergodicity from statistical mechanics in physics. We demonstrate consequences several real data examples previously published studies. then create simulated that illustrate independence processes differences, pair these with analytic results reinforce our conclusions. Finally, we discuss plausibility being general rule rather than exception for social behavioral processes, address common arguments against heeding implications research, offer possible solutions.

Advancements in music emotion prediction are driving AI-driven algorithmic composition, enabling the generation of complex melodies. However, bridging neural and auditory domains remains challenging due to semantic gap between brain-derived low-level features high-level musical concepts, making alignment computationally demanding. This study proposes a deep learning framework for generating MIDI sequences aligned with labeled predictions through supervised feature extraction from domains. EEGNet is employed process data, while an autoencoder-based piano algorithm handles data. To address modality heterogeneity, Centered Kernel Alignment incorporated enhance separation emotional states. Furthermore, regression applied reduce intra-subject variability extracted Electroencephalography (EEG) patterns, followed by clustering latent representations into denser partitions improve reconstruction quality. Using metrics, evaluation on real-world data shows that proposed approach improves classification (namely, arousal valence) system’s ability produce better preserve temporal alignment, tonal consistency, structural integrity. Subject-specific analysis reveals subjects stronger imagery paradigms produced higher-quality outputs, as their patterns more closely training In contrast, weaker performance exhibited were less consistent.

Abstract Recent studies have demonstrated that the representations of artificial neural networks (ANNs) can exhibit notable similarities to cortical when subjected identical auditory sensory inputs. In these studies, ability predict is probed by regressing from ANN representations. Building upon this concept, our approach reverses direction prediction: we utilize as a supervisory signal train recognition models using noisy brain recordings obtained through non-invasive measurements. Specifically, focus on constructing model for music identification, where electroencephalography (EEG) collected during listening serve input. By training an EEG representations-representations associated with identification-we observed significant improvement in classification accuracy. This study introduces novel developing response external stimuli. It holds promise advancing brain-computer interfaces (BCI), decoding techniques, and understanding cognition. Furthermore, it provides new insights into relationship between activity
