The neurobiology of affiliation is the new scientific field that describes the neural, endocrine, and behavioral systems sustaining our capacity to love. There are three factors in the neurobiology of bonding:
Oxytocin - a large molecule produced by neurons in the hypothalamus - is known for coordinating bonding, sociality, and group living. Oxytocin targets mainly the amygdala, a center for fear and vigilance, the hippocampus, and the striatum, a locus of motivation and reward.
Oxytocin is released through the central part of the neuron as well as its extensions, called dendrites. The dendrites increase oxytocin release whenever attachment memories are used and prime us for a lifetime. Early attachment memories help us move without fear.

Neuroscience used to think that our brains got a set amount of neurons. However, studies in animal models show that new neurons are produced in the brain throughout the lifespan.
Vigorous aerobic exercise - about 30 to 40 minutes - is the only activity that triggers the birth of those new neurons. The new neurons are created in the region of the brain associated with learning and memory, partially explaining the link between aerobic exercise and improvement in memory.
Increased activity is seen in the brain’s frontal lobe after adopting a long-term habit of physical activity. After about 30 - 40 minutes of vigorous aerobic exercise, studies have recorded increased blood flow in this region, which is associated with clear thinking: planning ahead, focus and concentration, goal-setting, time management.
This area is also linked to emotion regulation, allowing us to recover faster from emotions.
