Lots has been written in the past 20 years about the brain and how its wiring directly impacts our emotional states.  One writer pointedly drew the distinction between the “mind” and the “brain” – that collection of billions of neurons, each with numerous axons that connect with others to create networks.  These networks are the pathways for our thougths and mental associations, as well as our most gripping emotions – Rage, Fear, Lust, Sexual Lust, Connection with Others, Seeking (exploring the environment for its rewards….basic aliveness and vitality).  Neuroscientist Jaak Panksepp has identified the specific neural networks where these feelings track.  Scientists for years have been able to experimentally stimulate areas of the brain and produce angry, fearful, lustful, exploring and anxious behavior.  Substantial evidence exists for the notion that chronic feeings of irritation or anxiety, for example, are actually reflections of a low-grade, constant activation of these neural networks.  This is perhaps, why neurofeedback therapy has been clinically found to ease these distressing states.
