The decision to engage in food-seeking behaviour depends on homeostatic signals relating to energy balance and the presence of competing motivational drives, as well as learned brain cues signaling food availability.  It is known that the needs of the body can direct behavioural and neural processing toward motivationally relevant sensory cues. For example, human neuroimaging studies have consistently found specific cortical areas with biased responses … Continue reading Neuroimaging shows the effect of hunger on the brain’s response to food cues.
