Correlazione tra la distribuzione dei neuroni callosali e rappresentazione della linea mediana nell'area somestesica prima (SI)
Experiments have been carried out in order to study in the first somato-sensory area (SI) the relationships between the topography of callosal neurones and the physiological map of the trunk. Horseradish peroxidase (HRP) was injected into the posterior sygmoid gyrus of one hemisphere of 20 adult cats. On 11 of them, the contralateral homotopic cortex was explored with tungsten microelectrodes on the day after HRP delivery. Neurones retrogradely labelled by HRP (callosal neurones) were grouped within...
