A simple, direct and rapid method for filling microelectrodes
Membrane characteristics of visual cortical neurons in in vitro slices
Properties of "possibly" cholinergic neurons ascending from the rat ponto-mesencephalic area: comparison with noradrenergic and serotonergic neurons.
Putative cholinergic neurons, which constitute a major group in the laterodorsal tegmental nucleus, have properties similar to those of monoaminergic neuron, except for the phasic and decrementing nature of their response to tail pinch.
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.
Tonic and phasic components of the ascending reticular activating system.
It is proposed that the reticular activating system is not a single system, but is composed of two systems arising from the brainstem: the noradrenergic projection conveying a rather tonic control, and the cholinergic projection responsible for the phasic aspects of the activating system.
Direct evidence for recurrent inhibition in sliced brain preparation of the cat's visual cortex.
The observation that the cell reported here produced inhibitory postsynaptic potentials following single spikes or bursts of spikes which were elicited by intracellularly applied current indicates that IPSPs have been mediated by the recurrent inhibitory circuit via axon collaterals of the impaled cell.
Fast and slow components in the electroretinogram of the gastropod.
The electroretinogram of the isolated eye of the gastropod (Haliotis discus) was studied with penetrating microelectrodes, and it was found that the slow component is more susceptible to light adaptation and chemicals.

It was concluded that the axons of primary sensory cells convey impulses spontaneously to the central nervous system through the electroretinogram of squid.
Electrophysiological properties of neurons of cat visual cortex studied in vitro
P-cells and I-cells in in vitro slices of the lateral geniculate nucleus of the cat.
It was concluded that there exist physiologically differentiated P- and I- cells in the LGN even at birth and that I-cells are responsible for intrageniculate inhibition.
