changes in spike frequency , membrane potential and input resistance of somata freshly isolated from neurons in the metathoracic ganglia of adult locusts ( schistocerca gregaria ) during bath and ionophoretic application of putative amino acid transmitters and analogues were studied using intracellular techniques . gamma-aminobutyrate , glycine , taurine , cysteine and dl-ibotenate hyperpolarized the isolated soma , the response to kainic acid was depolarizing whereas l-glutamate and l-aspartate evoked a variety of potential changes .
