abstract
Some examples of procedures used by feeding researchers are discussed in this unit and include ablation of neural function; inhibition of behaviors by selective neurotoxins and antisense oligonucleotides; staining of sensory and motor mechanisms; electrical stimulation of the brain; local injection and microdialysis of nutrients, neurotransmitters, and drugs; autoradiography and in situ hybridization of neurotransmitters with their receptors; electrophysiological techniques for multi- and single-unit recording of cells in the hypothalamus; and gene technology using inbred strains of genetically obese mice.
