“…The segregation of different retino‐tectal projections, revealed by means of extracellular recordings in the fish tectum (Maximova et al, ; Maximov et al, , ; Aliper et al, ), is consistent with the pattern demonstrated by classical morphological methods (Meek & Schellart, ), as well as with the new methods of Ca++ imaging and Brainbow genetic labeling (Abbas et al, ; Nikolaou et al, ; Robles, Filosa, & Baier, ; Robles, Smith, & Baier, ). Units with different properties are sequentially recorded in different TO layers during the perpendicular advance of a microelectrode.…”

“…Retinal orientation selective units are located in the underneath sublaminae, at the depth of about 100 μm. And finally, sustained responses of two other ON‐ and OFF‐types of GCs are recorded at the depth of about 200 μm, deeper than all other retinal units (Aliper et al, ).…”

“…The responses from a different group of GC units are recorded approximately at the same level of the retinorecipient layer where the OS units are detected, though far less frequently (Aliper et al, ). These units are not selective either to the direction of motion or to the orientation of stimuli and are not characterized by any spontaneous spike activity (Aliper et al, ; Maximov et al, ; Maximova, Maximov, Damjanović, Aliper, & Zaichikova, ). Neither do they respond to the switching of ambient light on and off as well.…”

Responses of ON‐ and OFF‐ganglion cells (GCs) were recorded extracellularly from their axon terminals in the medial sublamina of tectal retino‐recipient layer of immobilized cyprinid fish (goldfish and carp). These units were recorded deeper than direction selective (DS) ones and at the same depth where responses of orientation selective (OS) GCs were recorded. Prominent responses of these units are evoked by small contrast spots flickering within or moving across their visual field. They are not selective either to the direction of motion or to the orientation of stimuli and are not characterized by any spontaneous spike activity. We refer to these fish GCs as spot detectors (SDs) by analogy with the frog SD. Receptive fields (RFs) of SDs are organized concentrically: the excitatory center (about 4.5°) is surrounded by opponent periphery. Study of interactions in the RF has shown that inhibitory influences are generated already inside the central RF area. This fact suggests that RFs of SDs cannot be defined as homogeneous sensory zone driven by a linear mechanism of response generation. Physiological properties of fish SDs are compared with the properties of frog SDs and analogous mammalian retinal GCs—local edge detectors (LEDs). The potential role of the SDs in visually guided fish behavior is discussed.

“…It is now known how the depths of the axon terminals of GC and TN in the tectum correlate [Aliper et al, 2019;Damjanović et al, 2019]. Thus, the reactions of DS GC and DS TN are recorded at different depths.…”

In all animals the optic tectum (OT) (or superior colliculi in mammals) provides guidance for external attention; this is not the only function of the tectum but is critically important for the development of behavioral visual reactions. In fi sh, the OT is the main primary visual center. It receives signals from most ganglion cells (GC) of different (known) types in the retina. Knowledge of the properties -both structural and physiological -of the neurons in the OT is important for understanding the mechanisms organizing behavior. We recorded extracellular electrical activity in the OT in living adult fi sh (Carassius auratus gibelio). Simultaneous recordings were made of the responses of retinal GC (from their axon terminals) and tectal neurons (TN), probably from cell bodies. Four types of TN are described with directional selectivity (DS) (henceforth these neurons are termed DS TN) at different (defi ned) depths of the OT. In addition to these, rare sporadic spikes lacking DS and arising on stimulation at any locus in a large area were consistently recorded simultaneously (superfi cially) with the responses of caudorostral DS GC with the electrode in one position. These are presumptively the responses of superfi cial tectal neurons (superfi cial inhibitory neurons, SIN). Various different types of stimulation were applied with the aim of obtaining clear SIN responses. Comparison of the results of our electrophysiological studies with published data (most studies in this direction have used calcium imaging in transparent Danio rerio fry) showed that DS TN were identical to glutamatergic periventricular interneurons in the OT, while SIN were identical to GABAergic inhibitory interneurons (SIN). These latter presumptively mediate detection of the main object (pop-out) in the fi eld of vision.
