Optical detection of convergent projections in the embryonic chick NTS.
Multiple-site optical recording of neural activity was performed in the nucleus of the tractus solitarius (NTS) of the chick embryo with stimulation of the glossopharyngeal nerve (N. IX) and vagus nerve (N. X). We measured the amplitudes of the optical signals related to glutamate-mediated excitatory postsynaptic responses, and calculated the ratio of the signal evoked by simultaneous N. IX/N. X stimulation to the signal obtained after mathematical summation of the individual N. IX and N. X responses. The ratio was significantly lower than 100% in the rostral region of the NTS, in which postsynaptic responses were elicited by both N. IX and N. X stimulations. This result means that there is a convergence of visceral inputs via the N. IX and N. X in the embryonic chick NTS. The existence of the convergence suggests that the NTS performs complex integration of information from multiple sensory inputs from the early stages of embryogenesis.[1]References
