In this episode, we hear about Huntington’s and heart disease, insights into the academic job market, the effect of noise on whales, and how tiny ear movements can help detect the direction of a sound.
Ana Domingos of the Gulbenkian Science Institute in Portugal has forged a career learning why we like certain types of food. By looking at the reward system of the mouse brain, she has revealed pathways that explain why animals prefer sugar, and perhaps why it may factor so strongly in the Western diet.
The effects of chloride homeostasis can explain diverse responses of basal ganglia output neurons to putatively inhibitory inputs and may tune these neurons' synchrony, oscillations and behavior in decision-making scenarios.
Cortical astrocytes play key roles in NREM sleep by regulating sleep depth and duration through separate GPCR pathways, and differentially control neuronal slow-wave activity in local and remote cortical circuits.
