A human brain network linked to restoration of consciousness after deep brain stimulation - Nature Communications In people with severe brain injuries, stimulation restored consciousness by engaging a deep brain circuit for wakefulnessβ€”revealing a target that may also guide treatment in stroke and epilepsy.

Just dropped in @natcomms.nature.com: we show that re-engaging a thalamic–ventral tegmental circuit with deep brain stimulation can reignite consciousness in patients with severe brain injury. Work led by Aaron Warren, with @andreashorn.org @foxmdphd.bsky.social @ others! tinyurl.com/4kz8j89b

Brain rhythms in cognition -- controversies and future directions Brain rhythms seem central to understanding the neurophysiological basis of human cognition. Yet, despite significant advances, key questions remain unresolved. In this comprehensive position paper, w...

Top left: Raster plot showing the neural spiking of different types of neurons across layers. The red dots represent excitatory neurons, while the others represent parvalbumin-positive interneurons (blue), somatostatin-positive interneurons (green), and 5-HT3a receptor-positive interneurons (purple), respectively. Top right: Averaged firing rate of excitatory neurons across layers over time, calculated using a 2 ms time bin. Dash lines indicate the onset of flash stimuli. Bottom: Schematic illustration explaining the phase dependency. The synaptic input from the lateral geniculate nucleus (LGN) enters the region adjacent to basal dendrites in deeper layers (gray circle), which are highly responsive to this input (left). When the peak phase of AC flows in a downward direction (middle), the membrane potential in basal dendrites is depolarized, leading to a weaker driving force. It results in weaker (less negative) excitatory postsynaptic current (EPSC) affecting change in LFPs and vice versa during the trough phase.

Electrical #BrainStimulation can be used to modulate #brain activity but how does it affect the #CorticalLayers? This study shows that only the deeper layers show phase-dependent changes in local field potential components upon electrical stimulation @plosbiology.org πŸ§ͺ plos.io/406W3i5
