Long-term lateral hypothalamic single unit analysis and feeding behavior in freely moving rats.
Lateral hypothalamus activity was observed in 23 single units for more than 24 h each in freely moving rats. The activity of 3 neurons was circadian related: low in the day and high at night. Ten neurons responded with inhibition related to individual feeding acts. These two neuron types might be important for long-term feeding rhythm and short-term feeding behavior.
