AI Article Synopsis
- The study focused on cats that were narcotized and immobilized to investigate how the brain's cortex responds to stimulation of the visceral system.
- It was found that the cortical representation of visceral signals mainly highlights somatic signals, except in areas of maximum activity.
- Additionally, the visceral systems exhibited habituation to long-term stimulation, a process similar to what has been observed in other sensory systems.
Article Abstract
In experiments on cats which had been narcotized with chloralose and immobilized with myo-relaxants, we have studied cerebral cortical responses to stimulation of the visceral system. A peculiarity of the visceral afferent representation is the fact that the convergence of visceral and dermomuscular impulses is achieved with predominance of somatic signals in the cortical zones of visceral representation, with the exception of the focus of maximal activity (FMA). A second peculiarity is the fact that the visceral afferent systems develop habituation to prolonged stimulation. The principles of this development are similar to the general principles described in the literature for other sensory systems.
