Characteristics of responses of preoptic neurons to presentation of serial cortical stimuli
Abstract Responses of neurons of the medial (MPO) and lateral (LPO) preoptic region (RPO) and adjacent hypothalamic structures to serial stimuli (6–300/sec) of the prefrontal (area 8) and cingulate (area 24) cortex, piriform lobe (periamygdaloid cortex — RPA), and hippocampus (area CA3) were investi...

| 520 | |a Abstract Responses of neurons of the medial (MPO) and lateral (LPO) preoptic region (RPO) and adjacent hypothalamic structures to serial stimuli (6–300/sec) of the prefrontal (area 8) and cingulate (area 24) cortex, piriform lobe (periamygdaloid cortex — RPA), and hippocampus (area CA3) were investigated in acute experiments on cats under ketamine anesthesia. Four main types of responses were found: excitatory, inhibitory, excitatory on-off effect, and inhibitory on-off effect. With the use of stimuli with increasing frequencies, the direction of the response remained constant, only its intensity changed. Neurons responding to presentation of serial stimuli were localized mainly in the central part of the MPO and basal part of the LPO, where the most pronounced foci of convergence were observed. During serial stimulation of cortical structures, inhibitory responses occurred considerably more often than excitatory (ratio 3.4:1). The presence of a gradient of inhibition was established from new to old (in a phylogenetic respect) brain formations in a number of stimulated structures. In the case of stimulating the neocortex (proreal gyrus), the predominance of inhibitory responses over excitatory was minimum (1.7:1); it increased (1.9:1) in the case of stimulating the intermediate cortex (cingulate gyrus), still more (4.5:1) under conditions of stimulating the paleocortex (periamygdaloid cortex), and in the case of stimulating the archicortex (10.2:1). | ||

Characteristics of responses of preoptic neurons to presentation of serial cortical stimuli |
| abstract |
Abstract Responses of neurons of the medial (MPO) and lateral (LPO) preoptic region (RPO) and adjacent hypothalamic structures to serial stimuli (6–300/sec) of the prefrontal (area 8) and cingulate (area 24) cortex, piriform lobe (periamygdaloid cortex — RPA), and hippocampus (area CA3) were investigated in acute experiments on cats under ketamine anesthesia. Four main types of responses were found: excitatory, inhibitory, excitatory on-off effect, and inhibitory on-off effect. With the use of stimuli with increasing frequencies, the direction of the response remained constant, only its intensity changed. Neurons responding to presentation of serial stimuli were localized mainly in the central part of the MPO and basal part of the LPO, where the most pronounced foci of convergence were observed. During serial stimulation of cortical structures, inhibitory responses occurred considerably more often than excitatory (ratio 3.4:1). The presence of a gradient of inhibition was established from new to old (in a phylogenetic respect) brain formations in a number of stimulated structures. In the case of stimulating the neocortex (proreal gyrus), the predominance of inhibitory responses over excitatory was minimum (1.7:1); it increased (1.9:1) in the case of stimulating the intermediate cortex (cingulate gyrus), still more (4.5:1) under conditions of stimulating the paleocortex (periamygdaloid cortex), and in the case of stimulating the archicortex (10.2:1). |

During serial stimulation of cortical structures, inhibitory responses occurred considerably more often than excitatory (ratio 3.4:1). The presence of a gradient of inhibition was established from new to old (in a phylogenetic respect) brain formations in a number of stimulated structures. In the case of stimulating the neocortex (proreal gyrus), the predominance of inhibitory responses over excitatory was minimum (1.7:1); it increased (1.9:1) in the case of stimulating the intermediate cortex (cingulate gyrus), still more (4.5:1) under conditions of stimulating the paleocortex (periamygdaloid cortex), and in the case of stimulating the archicortex (10.2:1). |

Abstract Responses of neurons of the medial (MPO) and lateral (LPO) preoptic region (RPO) and adjacent hypothalamic structures to serial stimuli (6–300/sec) of the prefrontal (area 8) and cingulate (area 24) cortex, piriform lobe (periamygdaloid cortex — RPA), and hippocampus (area CA3) were investigated in acute experiments on cats under ketamine anesthesia. Four main types of responses were found: excitatory, inhibitory, excitatory on-off effect, and inhibitory on-off effect. With the use of stimuli with increasing frequencies, the direction of the response remained constant, only its intensity changed. Neurons responding to presentation of serial stimuli were localized mainly in the central part of the MPO and basal part of the LPO, where the most pronounced foci of convergence were observed. During serial stimulation of cortical structures, inhibitory responses occurred considerably more often than excitatory (ratio 3.4:1). The presence of a gradient of inhibition was established from new to old (in a phylogenetic respect) brain formations in a number of stimulated structures. In the case of stimulating the neocortex (proreal gyrus), the predominance of inhibitory responses over excitatory was minimum (1.7:1); it increased (1.9:1) in the case of stimulating the intermediate cortex (cingulate gyrus), still more (4.5:1) under conditions of stimulating the paleocortex (periamygdaloid cortex), and in the case of stimulating the archicortex (10.2:1). |
