A novel analysis reveals distinct periodic and aperiodic EEG activity during working memory, challenging oscillatory-centric views while establishing aperiodic activity as a more sensitive marker of cognitive state.
A jumping spider discriminates familiar from novel conspecifics for hours, indicating recognition and long-term memory in a miniature-brained, asocial arthropod, highlighting learning and internal representations in small nervous systems.
Removal of type-I nNOS neurons decreased delta-band power in the LFP, lowered dilation to sustained stimulation, decreased the interhemispheric coherence of neural and hemodynamic signals, and reduced vasomotion amplitude.
Eye-specific differences in presynaptic release site addition and clustering correlate with axonal segregation outcomes during retinogeniculate refinement in the mouse.
Spatially and temporally overlapping target and distractor are both rhythmically sampled at ~1 Hz, and the phase relationship between target sampling and distractor sampling predicts behavior.

Increased transfer of axonal mitochondria to optic nerve astrocytes after expression of glaucoma-associated Optineurin variants suggest that increased transcellular degradation of axonal mitochondria may play a causative role in at least some forms of glaucoma.
