5 Απρ 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.
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.
The core findings of our analysis are: (i) the presence of distinct spatiotemporal motifs of GWEs with three principal motifs dominating throughout different anesthetic brain states; (ii) the systematic change of principal motif prevalence during recovery from anesthesia; and (iii) the temporal compression of the motifs both at the local ...
