Male and Female Mice Have Different Brain Cells

Does this mean that transgendering is not so easy? Listen up transgender people: Your transgender transition is incomplete! :-)

Amazing what little we still know about our brains! But so called climate scientists claim they can predict climate (a very complex system) up to 100 years into the future with their climate models! Laughable!

"The hypothalamus is a fundamental region of the brain found in all vertebrates including humans. Previous studies have shown that a specific anatomic subdivision in the hypothalamus, called the ventrolateral subdivision of the ventromedial hypothalamus (VMHvl), contains cells that control aggression and mating behaviors. In these studies, strong stimulation of these neurons in male and female mice immediately caused the animals to become aggressive, even in the absence of any threat. However, weak stimulation caused the mice to begin mating behaviors.

In this new work ... the researchers examined gene expression in individual cells in the VMHvl. This was made possible by advanced transcriptomic techniques that can enumerate and identify the RNA transcripts that a cell contains; this information can then be used to classify different cell types. Previous studies were only able to examine 10 percent of the transcripts in each cell, whereas this study looked at a larger proportion of transcripts. The team discovered that there are 17 different types of brain cells in this tiny region alone. What is more, an examination of the patterns of gene expression revealed that some of these 17 cell types are much more abundant in male mice than in females, while others are found only in females. ... but this is the first discovery of types of cells that are sex-specific in a mammalian brain"

"Other researchers have previously found genes that are switched on, or expressed, exclusively in male or female brains, but this is the first demonstration of sex-specific neuron types in mammals, the authors said."

Scientists find mouse neurons that are unique to male or female brains Study linking behaviors with cells in an ancient section of the brain also pinpointed a neuron tied to social fear
