STUDIES ON THE INTRARETINAL ACTION POTENTIAL
TLDR
Effects of some chemical agents upon the EIRG (electro-intraretinogram) of the bullfrog's eye were examined with the micro-pipette inserted into different retinal layers, supporting the view that one part of the d-wave has its origin similar to the b-wave.

TLDR
Because of the universal lamellation within the rod and cone outer segments, it looks as if there were no appreciable intracellular space, but yet Toyoda, Nosaki & Tomita (1969), and Toyoda et al. (1970) were successful in intrACEllular recording from the outer segments of single rods of the nocturnal gecko and frog.

Descriptions are made of recent developments in research on the S potential and the ERG, two major responses in the vertebrate retina which undoubtedly represent important processes that are
On the R Membrane in the Frog's Eye: Its Localization, and Relation to the Retinal Action Potential
TLDR
The results obtained from the excised opened eye of the frog support the conclusion of Brown and Wiesel, and some of the conflicting evidence concerning the origin of the E R G obtained with microelectrodes can be resolved in terms of this factor.
STUDIES ON THE INTRARETINAL ACTION POTENTIAL PART I. RELATION BETWEEN THE LOCALIZATION OF MICRO-PIPETTE IN THE RETINA AND THE SHAPE OF THE INTRARETINAL ACTION POTENTIAL
TLDR
It was found that the shape of the action potential thus detected intraretinally differs remarkably according to the localization of the electrode, considerations on which have led to a belief, that P I and the resting potential originate in most certainty in the receptors layer, and that P III originates in bipolar cells layer.
Microelectrode study of spreading depression (SD) in frog retina-Müller cell activity and [K+] during SD--.
TLDR
The mechanism of SDP, the field potential change associated with SD, is discussed from a proposed model and it is revealed that upon SD the Müller cells immediately start to cleanse the extracellular space of excess K+ which is probably a product of pathologically enhanced synaptic activity in the inner plexiform layer.
