Somatovisceral interactions in the rat dorsal column nuclei
Recent studies have revealed that noxious visceral inputs travel in the dorsal column pathway, and interactions between colorectal noxious and tactile inputs occur in the ventrobasal thalamus. This investigation was to test whether the somatovisceral interactions also take place in the dorsal column nuclei (DCN). Forty-five single DCN neurons of anesthetized rats responsive to colorectal disten...

متن کاملCoding of position by simultaneously recorded sensory neurones in the cat dorsal root ganglion.
Muscle, cutaneous and joint afferents continuously signal information about the position and movement of individual joints. How does the nervous system extract more global information, for example about the position of the foot in space? To study this question we used microelectrode arrays to record impulses simultaneously from up to 100 discriminable nerve cells in the L6 and L7 dorsal root ga...
متن کاملProcessing of vibrotactile inputs from hairy skin by neurons of the dorsal column nuclei in the cat.
The capacity of single neurons of the dorsal column nuclei (DCN) for coding vibrotactile information from the hairy skin has been investigated in anesthetized cats to permit quantitative comparison first with the capacities of DCN neurons responding to glabrous skin vibrotactile inputs and second with those of spinocervical tract neurons responding to vibrotactile inputs from hairy skin. Dynami...
متن کاملDoublet and burst firing patterns within the dorsal column nuclei of cat and man.
We have examined extracellularly the firing pattern of neurons in the cat external cuneate nucleus and in the human main cuneate nucleus, focusing upon both the spontaneous firing patterns and its modification by natural stimulation. Many of these neurons exhibit stereotyped doublet or burst firing patterns, e .g., the interval between the spikes might be 1 .0 + 0 .1 msec in a given cell . For ...
