The three main types of inhibitory neurons in mouse primary visual cortex respond differently to locomotion in darkness and during visual stimulation, revealing context-dependent responses to changes in behavioral state.
A sexually dimorphic circuit node controls a persistent, internal state that promotes fighting and mating in Drosophila, revealing parallels with mammalian systems suggestive of a conserved circuit "motif" controlling social behaviors.
A quantitative video tracking analysis reveals that to gain the nutrients they need, flies change their decisions to exploit foods with different nutrient contents and explore the environment according to their internal amino acid and reproductive states.
Layer 5 neuron apical tuft in mouse visual cortex display widespread, highly correlated calcium signals, with a strong and asymmetric coupling to somatic signals, independent of visual stimulation and locomotion.
Stimulation of specific neurons within the hypothalamus triggers a fear-like emotion state and behavioral response in mice, challenging the textbook view that the hypothalamus serves simply as a relay for emotion states encoded in the amygdala.
