Inflammation in Brain’s Immune Cells Triggers Depressive Behavior in Mice
Dan Robitzski | Nov 17, 2022 | 5 min read
In stressful conditions, specialized protein complexes in microglia induce neurotoxic activity in astrocytes that leads to the change in behavior.
(Left) The optic lobes are thought to be involved in visual processing. In this study, researchers found that guppies with larger optic lobes more quickly learned a visual discrimination task—identifying which color well contained food. (Right) The fish telencephalon is thought to be involved in spatial learning, memory, and inhibitory control. Here, the researchers found that a larger telencephalon might enhance the fish’s cognitive flexibility, allowing them to more quickly associate food with a new color after the researchers switched it.
