Effects of stimulating the dorsal raphe nucleus of the rat on neuronal activity in the dorsal lateral geniculate nucleus
It is suggested that serotonin released from terminals of DRN neurons exerts long-latency and long-lasting inhibition of LGNd relay neurons, the serotonergic projection from the DRN acts to control excitation levels of the forebrain. Expand

The results suggest that vagal preganglionic neurones colocalize functionally nicotinic and P2X purinergic receptors. Expand
Electrophysiology of ascending, possibly cholinergic neurons in the rat laterodorsal tegmental nucleus: comparison with monoamine neurons
In urethane-anesthetized rats single neuronal activity was recorded in the laterodorsal tegmental nucleus (LDT), which has a dense complement of cholinergic neurons, and in the dorsal raphe and locus… Expand
Burst discharges of thalamic reticular neurons: an intracellular analysis in anesthetized rats
It is suggested that excitatory synaptic inputs to S-TR neurons with the spindle rhythm are responsible for the rhythmic generation of SDs and evidence has been provided that EPSPs contribute to the mechanism for triggering SDs. Expand
Membrane characteristics of visual cortical neurons in in vitro slices
In in vitro slices prepared from the visual cortex of cats a total of 15 neurons were studied for their membrane properties by passing currents through an intracellular microelectrode and by… Expand
Arachidonic acid activation of potassium channels in rat visual cortex neurons
There exists a novel type of K+ channel activated by arachidonic acid which may play a critical role in modulating neuronal excitability in cortical neurons, suggesting that the channel is not Ca2+ dependent. Expand

The rate of spontaneous discharge of geniculate neurons was raised by electrical stimulation of the reticular formation and their ability to respond to intermittent light was enhanced. Expand

Light adaptation of suitable intensity was favorable for the manifestation of negative potentials in the surrounding area, and this effect is to be ascribed to suppression of the effect of stray light by light adaptation. Expand
Cholinergic influence of the laterodorsal tegmental nucleus on neuronal activity in the rat lateral geniculate nucleus.
The results show that the cholinergic projection from the LDT may be involved in the ascending reticular activating system, although the functional significance of the activating system in visual information processing in the geniculate nucleus remains to be clarified. Expand
