Human Brain Project study offers insights into neurotransmitter receptor organisation
Researchers from the Human Brain Project (HBP) and collaborating institutions have made significant strides in understanding the distribution of receptors in the brain. Through a comprehensive mapping study, they discovered two distinct gradients of receptor expression per neuron in the cortex, shedding light on its organisation and functionality.
