[Early auditory evoked potentials in normal sheep and in sheep with trypanosomiasis]. / Potentiels évoqués auditifs précoces chez le mouton sain et chez le mouton trypanosomé.

In human and animal clinics, the early auditory potential has been used for a long time in the detection of lesions through the internal auditory way in the cerebral trunk. The aim of this work tries to determine if this non invasive test is apt to show up and to follow the evolution of lesions at the level of auditory way in the cerebral trunk of sheep with trypanosomiasis. According to the human technic, the list of the early auditory potential was realized against ten healthy sheep and ten sheep with trypanosomiasis (Trypanosoma brucei brucei) at the nervous phase. No significant anomalies exist in the sheep with trypanosomiasis. The results are discussed.
