taste transduction

the sequence of events involved in converting the detection of chemical molecules into taste signals. Gustatory stimuli interact with the microvillus of a taste cell, which results in changes in activity in the ion channels within taste receptors. The subsequent depolarization within these receptors triggers the release of neurotransmitters that stimulate sensory neurons in the peripheral nervous system (see greater superficial petrosal nerve). The mechanisms of transduction vary with the type of gustatory stimulus, although each taste cell is capable of transducing different stimuli. Also called gustatory transduction.

support group

a group similar in some ways to a self-help group in that members who share a problem come together to provide help, comfort, and guidance. A primary distinguishing feature of support groups is in their leadership: a professional or agency-based facilitator who often does not share the problem of members. In addition, support groups often last for only a limited predetermined number of sessions, and a fee for attendance is sometimes charged. Also called social support group.
