A new extensive approach to single unit responses using multisite recording electrodes: application to the songbird brain.

摘要: One of the most challenging issues in neuroethology concerns neural substrates for song production, perception and learning songbirds. However, electrophysiological studies system songbirds are often fragmented centered on a small number selected neurons. Here, we have developed new extensive approach to record great single units brain songbird, European starling. The aim this is formulate quantitative assumptions about characteristics nucleus investigated: e.g. proportion auditory neurons, neuronal selectivity, etc. We applied mapping method using multisite recording electrodes online isolation single-units, without preselecting neurons with search stimulus. As an example application technique, mapped responses variety natural artificial acoustic stimuli recorded systematically throughout HVC both awake anaesthetized male starlings. This appears be powerful allowed us quantitatively compare obtained birds by over 1000 units. think that, future, will enable characterize parts nuclei or entire better understand how works.
