Ca2+ imaging of self and other in medial prefrontal cortex during social dominance interactions in a tube test
The study of social dominance interactions between animals offers a window onto the decision-making involved in establishing dominance hierarchies and an opportunity to…
Nuria Garcia-Font et al. | PNAS | July 26, 2022Noise correlations in neural ensemble activity limit the accuracy of hippocampal spatial representations
Neurons in the CA1 area of the mouse hippocampus encode the position of the animal in an environment. However, given the variability in individual neurons responses, the…
Hazon O et al. | Nature Communications | July 25, 2022Dopamine subsystems that track internal states
Food and water are rewarding in part because they satisfy our internal needs. Dopaminergic neurons in the ventral tegmental area (VTA) are activated by gustatory rewards…
Grove JCR et al. | Nature | July 13, 2022Nested calcium dynamics support daily cell unity and diversity in the suprachiasmatic nuclei of free-behaving mice
The suprachiasmatic nuclei (SCN) of the anterior hypothalamus host the circadian pacemaker that synchronizes mammalian rhythms with the day-night cycle. SCN neurons are…
Hussein LEC et al. | PNAS Nexus | July 11, 2022Sound induces analgesia through corticothalamic circuits
Sound—including music and noise—can relieve pain in humans, but the underlying neural mechanisms remain unknown. We discovered that analgesic effects of sound depended…
Wenjie Zhou et al. | Science | July 7, 2022Pattern decorrelation in the mouse medial prefrontal cortex enables social preference and requires MeCP2
Sociability is crucial for survival, whereas social avoidance is a feature of disorders such as Rett syndrome, which is caused by loss-of-function mutations in MECP2. To…
