Spinal motor neurons in dazzling detail. ✨
Each green dot is a spinal motor neuron - crucial but rare cells making up just 1% of neurons in the spinal cord. In diseases like ALS, they are selectively damaged, making them of special interest to neuroscientists.

Amygdala–liver signalling orchestrates glycaemic responses to stress - Nature
Studies in mice show that acute stress activates hyperglycaemia via activation of a medial amygdala–ventral hypothalamic circuit that controls glucose metabolic responses in the liver, independently of adrenal and pancreatic hormones.

My med school textbook says stimulants like Ritalin treat hyperactivity by “stimulating” the brain’s attention and cognitive control systems. We studied children taking stimulants in the ABCD Study, and the largest differences were actually in arousal and reward networks! Check out our preprint!
