1 Ιουν 2024 · Illustrating brain states as infra-slow waves that recruit different sets of brain areas at varying phases. State discretization oversimplifies brain dynamics that oppose the fundamental ebb-and-flow nature of brain activity.
5 Απρ 2024 · Considering brain states as waves has several benefits for contemporary neuroimaging and neuroscience goals such as predictive modeling. However, future studies will be necessary to uncover the functional significance of wave features.
There is ample evidence of wave-like activity in the brain at multiple scales and levels. This emerging literature supports the broader adoption of a wave perspec-tive of brain activity. Specifically, a brain state can be described as a set of recurring, sequential patterns of propagating brain activity, namely a wave.
1 Ιουν 2024 · We propose that brain states should be conceptualized as waves – recurring patterns of activity that sequentially propagate with different delay times. This definition emphasizes both the spatial and temporal patterns of brain activity.
1 Απρ 2024 · It is shown that spiral-like, rotational wave patterns (brain spirals) are widespread during both resting and cognitive task states, and that multiple, interacting brain spirals are involved in coordinating the correlated activations and de-activations of distributed functional regions.
15 Ιουλ 2024 · By analyzing high-resolution neural activity recorded in ten mouse brain regions over 24 h, we reveal that brain states are reliably identifiable (embedded) in fast, nonoscillatory activity.
These findings highlight that functional endogenous interactions between distant cortical areas are not only constrained by anatomical connectivity, but can also be modulated by the brain state.
