Firing of ‘possibly’ cholinergic neurons in the rat laterodorsal tegmental nucleus during sleep and wakefulness
The results suggest that: (1) the laterodorsal tegmental nucleus (LDT) of undrugged rats is composed of cholinergic neurons with heterogenous characteristics in relation to sleep/wakefulness; and (2) some te segmental cholinerg neurons play a privotal role in induction and maintenance of PS. Expand
Olfactory evoked potentials: experimental and clinical studies.
It is demonstrated that evoked potentials from the olfactory tract and the scalp following electrical stimulation of the Olfactory mucosa originate specifically from theOlfactory system, suggesting that the response was synaptically mediated. Expand

Glossopharyngeal Nerve Evoked Potentials after Stimulation of the Posterior Part of the Tongue in Dogs
The glossopharyngeal nerve action potentials and cortical potentials elicited by the stimulation of the posterior one-third of the tongue can be recorded and represent a new means for intraoperative monitoring of patients undergoing surgery in the brainstem via the cerebellopontine angle. Expand
Ascending Cholinergic and Monoaminergic Systems in the Brainstem: Do they Constitute a Reticular Activating System?
With the new techniques of neuroanatomy several clearly defined structures with ascending projections have been discerned in or near the putative ARAS, and the obvious question is whether one or more of these newly specified entities is, or constitute a major component of, the ARAS. Expand
Experimental study for identification of the facial colliculus using electromyography and antidromic evoked potentials.
The most suitable electrophysiological stimulation of the fourth ventricular floor for identification of the facial colliculus was 0.1-mA monopolar stimulation, and a recording of an antidromic facial evoked potential can identify the facial Colliculus more safely than direct stimulation. Expand

This invention provides improved electrical connections between the extensometric elements and a measuring bridge circuit consisting of contact rings carried by and insulated from the shaft, and connected to the elements, and a stator enclosing the rings and making contact therewith through internal grooves filled with mercury.
