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.
Early-life environment shapes how wild bats behave as adults, showing that developmental experience, rather than innate predisposition, drives individual differences in foraging behavior.
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.
Fitness constraints on the HIV envelope protein are highly similar in humans and rhesus macaques, emphasizing the utility of macaque models of infection and antibody development.
A boundary between the sensory and nonsensory domains contains cells that undergo a series of morphological changes and form basal constriction to separate the segregating inner ear sensory organs.
