Multiple types of navigational information are independently encoded in the population activities of the dentate gyrus neurons
The dentate gyrus (DG) plays critical roles in cognitive functions, such as learning, memory, and spatial coding, and its dysfunction is implicated in various…
Tomoyuki Murano et al. | PNAS | August 5, 2022Transformations of neural representations in a social behavioral network
Mating and aggression are innate social behaviours that are controlled by subcortical circuits in the extended amygdala and hypothalamus. The bed nucleus of the stria…
Yang B et al. | Nature | August 3, 2022Ca2+ 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…
