New findings reveal how anesthesia-induced unconsciousness differs from normal sleep in relation to delta wave activity in the brain.
Anterior cingulate cortex neurons project connections to the superior colliculus. The superior colliculus carries out reflexive movements. The study finds the purpose of the ACC neurons connections to the SC is to over-rider the SC when executive control is essential.
A newly developed artificial intelligence algorithm can accurately and reliably assess unconsciousness in patients under anesthesia based on brain activity.
In both human cell and mouse models of Huntington's disease, RNA from mitochondria was misplaced within spiny projection neurons. The stray RNAs, which looked different to cells than RNA derived from the cell nucleus, trigger an immune reaction that can lead to striatal cell type vulnerability.
Findings support modern thought that neural networks store information by making short-term alterations to the synapses. The study sheds new light on short-term synaptic plasticity in recent memory storage.
Study identifies a key role locus coeruleus neurons play in attentional control.
Brain mapping study reveals memory engrams are widely distributed throughout the brain, including among regions not previously realized.
