Amphetamine reduces reward signaling by neurons in rat prefrontal cortex, but increases the stability of population dynamics, which account for animals’ increased task engagement, despite reduced reward motivation.
Two distinct subpopulations of CA1 neurons that increased or decreased their firing rate during delay were identified, suggesting that they have distinct roles in the valuation process in the hippocampus.
Generation of a premotor/motor neuron comprehensive TEM reconstruction, functional optogenetics, and recurrent network modeling reveals different phase relationships among a subset of Drosophila motor neurons in forward versus backward locomotion.
Sperm and egg development are temperature sensitive, enabling males and females to significantly improve their reproductive success by matching gamete function to varying thermal environments for fertilisation and offspring development.
A neuroanatomical analysis of Rimicaris exoculata provides insights into these animal’s brain architecture to illustrate possible adaptations to the hydrothermal vent habitat with its extreme physicochemical conditions.
