The role of serotonin in food intake has been studied for decades. Food intake is mainly
regulated by two brain circuitries:(i) the homeostatic circuitry, which matches energy intake …

Central regulation of food intake is a key mechanism contributing to energy homeostasis.
Many neural circuits that are thought to orchestrate feeding behavior overlap with the brain's …

Hypothalamic neurons that co-express agouti-related protein (AgRP), neuropeptide Y and γ-
aminobutyric acid (GABA) are known to promote feeding and weight gain by integration of …

Mammals exhibit daily anticipatory activity to cycles of food availability. Studies on such food
anticipatory activity (FAA) have been conducted mainly in nocturnal rodents. They have …

Context-dependent plasticity in auditory processing is achieved in part by physiological
mechanisms that link behavioral state to neural responses to sound. The neuromodulator …

Key points• Persistent vulnerability to relapse represents a major challenge in the treatment
of drug addiction. The brain circuitry that underlies relapse‐like behaviour can be …

SUMMARY Neuromodulation by serotonin (5-HT) could link behavioral state and
environmental events with sensory processing. Within the auditory system, the presence of 5 …

Serotonin is a neurotransmitter that is synthesized and released from the brainstem raphe
nuclei to affect many brain functions. It is well known that the activity of raphe serotonergic …

Context is critical to the adaptive value of communication. Sensory systems such as the
auditory system represent an important juncture at which information on physiological state …

Previous studies indicate that the modification of adrenergic neurotransmission in median
raphe nucleus (MRN) enhances or removes an inhibitory influence on food intake, possibly …
