We investigated the responses of single neurons to typical guinea pig vocalizations (purr, chutter, chirp and whistle) in the medial geniculate body of guinea pigs. The patterns of the peristimulus time histograms (PSTHs) correlated well with the sound temporal envelope in calls with short phrases (purr, chirp). The dominant onset character of the neuronal responses resulted in a lower correlation between the sound envelope and the PSTH pattern in the case of longer calls (chutter and whistle).
Hodnotili jsme odpovědi jednotlivých neuronů v corpus geniculatum mediale morčete na typické vokalizace morčat (purr, chutter, chirp a whistle). Tvar peristimulačního histogramu (PSTH) dobře koreloval s časovou obálkou zvuků obsahujících krátké segmenty (purr, chirp). Vzhledem k výrazné onsetové reakci neuronů (tj. odpověď pouze na začátek zvuku) byl tvar PSTH slabě korelován s časovou obálkou delších zvuků (chutter and whistle).
