The result holds even when just one of a pair receives oxytocin or vasopressin, indicating some sort of non-verbal communication between the animals. Oxytocin’s effects […]

Oxytocin Filters Inputs To VTA Dopamine Neurons

The mammalian brain contains millions of nerve cells or neurons that communicate with each other via a process called neurotransmission. To send a message to its neighbor, a neuron releases a chemical called a neurotransmitter into the space between the cells. The neurotransmitter then binds to receiver proteins on the target cell. Another group of […]
