Abstract

In the prothoracic ganglia of the cricket Gryllus bimaculatus two local auditory interneurones, ON1 and ON2, were labelled for electron microscopy by intracellular injection of horseradish peroxidase following physiological characterisation. The neurones branch in the median ventral association centre and the root of nerve 5 on both sides of the ganglion. As they are very similar in shape and position they may share a common embryological origin. Differences are found in the details of the fine branching pattern and in their physiology as ON1 is tuned particularly to low sound frequencies of 4-5 kHz whereas ON2 is more sensitive to frequencies above 8 kHz. Although the ON1 neurones inhibit each other and are involved in the inhibition of other auditory neurones they were not labelled by antibodies against the inhibitory transmitter GABA and their vesicles differ significantly from those in neurones that are. The same is true of the ON2 neurones whose vesicles also differ significantly from those in ON1 supporting light-microscope evidence that they may use different transmitters. The distribution of input and output synapses on the ipsilateral and contralateral branches of ON1 and ON2, and the proportion of the synapses made fr...Continue Reading

Auditory Perception

Auditory perception is the ability to receive and interpret information attained by the ears. Here is the latest research on factors and underlying mechanisms that influence auditory perception.
