five

Neurons
- Using designer receptors exclusively activated by designer drugs (DREADD) technology to provide specific and reversible regulation of neuronal activity in mice, we have demonstrated that acute activation of AgRP neurons rapidly and dramatically induces feeding, reduces energy expenditure, and ultimately increases fat stores. (jci.org)
- Of interest, activating AgRP neurons potently increased motivation for feeding and also drove intense food-seeking behavior, demonstrating that AgRP neurons engage brain sites controlling multiple levels of feeding behavior. (jci.org)
- Acute stimulation of AgRP neurons in mice fed ad lib led to a significant increase in the break point, similar to the break point observed in fasted mice. (jci.org)
- In turn, glutamatergic signaling links these interneurons to pharyngeal neurons implicated in feeding behavior. (nih.gov)
- This powerful new tool for identifying and characterizing neural circuitry has lead to the identification of a pair of neurons now called Fdg neurons in the fruit fly that decide when to eat and initiate the subsequent feeding action. (bio-medicine.org)
- To isolate the neurons responsible for sensing food and initiating the complex feeding program in Drosophila , UMMS scientists had to develop a method of studying the behavior of freely moving flies while targeting and manipulating individual neurons. (bio-medicine.org)
- Subsequent experiments revealed that the feeding mechanism initiated by activating the transgenes was being controlled by a single pair of neurons in the fly's brain. (bio-medicine.org)
- Furthermore, these feeding (Fdg) neurons were responsible for synthesizing cues about available food and hunger, and using them to start the feeding mechanism. (bio-medicine.org)
- This means that these neurons are integrating both internal and external stimuli in order to initiate a complex feeding behavior with multiple motor programs. (bio-medicine.org)
regulate
