DescriptionFour parts of the guinea pig brain were stimulated with tungsten electrodes under urethane anaesthesia to record sequences of vocalizations. These vocalizations were then compared with a series of templates of spontaneously produced vocalizations so that they could be identified as similar to the appropriate natural call. Each electrode position was stimulated a number of times at the same or different current levels and the identity and time of produced calls was recorded.

Data typeRecordings of stimulated calls as .wav files. Templates of naturally occuring calls used with Avisoft software. Excel spreadsheets with the times and identity of each call produced and the brain structure that had been stimulated.

Data collection methodAudio files were recorded while the guinea pig produced a series of vocalizations in response to electrical brain stimulation. Each call sequence was isolated and analysed against natural templates with Avisoft Bioacoustics software to identify each call and record the start of the call in relation to the start of stimulation.
