Vertical line in each of the raster displays and histograms indicates the stimulus onset. Neuronal responses in the nucleus accumbens shell during sexual behavior in male rats. Motter, Alexandre Pouget, Adam Reeves, John H. This study was approved by the Committee for Animal Experiments and Ethics at the University of Toyama. These results indicated that these characteristic changes were specific to Early and Late phases. Parvalbumin neurons and gamma rhythms enhance cortical circuit performance.
The neurophysiological correlates of colour induction, colour and brightness contrast. Responses of monkey basal forebrain neurons during visual discrimination task. Cognitive functions of gamma-band activity: memory match and utilization. . The development of visual cortical properties depends on visuo-proprioceptive congruence.
The text provides a solid introduction for newcomers and a strong overview of the current state of the field for experts. University of California Press, 1997. The comparisons indicated that low-level features color histogram, spatial-frequency power distribution of snakes were significantly different from those of other categories see. Then, after an interval of 1. Amygdalar and hippocampal neuron responses related to recognition and memory in monkey. The significance of the excitatory or inhibitory responses to each stimulus was determined by comparing between the 100-ms pre and 500-ms post periods with a Wilcoxon signed-rank test. Abnormal visual experience and spatio-temporal properties of area 18 neurones in the cat.
Topics discussed include: Anatomy, essential for understanding the neural substrates of multisensory processing Neurophysiological bases and how multisensory stimuli can dramatically change the encoding processes for sensory information Combinatorial principles and modeling, focusing on efforts to gain a better mechanistic handle on multisensory operations and their network dynamics Development and plasticity Clinical manifestations and how perception and action are affected by altered sensory experience Attention and spatial representations The last sections of the book focus on naturalistic multisensory processes in three separate contexts: motion signals, multisensory contributions to the perception and generation of communication signals, and how the perception of flavor is generated. Light sensitivity, adaptation and saturation in mammalian rods. Frequency of oscillation of a given neuron corresponds to wave frequency of the Gabor function ν. Finally, a new stimulus was presented target phase. The monkeys reached a 96% correct-response rate after 3 months of training ,.
The rules of multisensory integration evident at the level of the single neuron are also consistent with studies of intact behaving animals. The task was initiated by a buzzer tone. We have been doubly fortunate in that these contributors, like ourselves, were at one time or another members of the group belonging to the scientific staff of Dr. Huk, Minami Ito, Laurent Itti, Christof Koch, Peter E. Rhythms for cognition: communication through coherence. Faces are complex social stimuli for primates, suggesting that faces might activate sophisticated memories that are stored in the distributed cortical areas.
This we have attempted to do in this monograph. Dangerous animals capture and maintain attention in humans. Corticotectal relationships: direct and 'indirect' corticotectal pathways. Knowledge of the basic mechanisms by which our brain can analyze, reconstruct, and interpret images in the external world is of fundamental importance for our capacity to understand the nature and causes of visual deficits, such as those resulting from ischemia, abnormal development, neuro-degenerative disorders, and normal aging. Although the spatial, temporal, and multiplicative characteristics of multisensory integration were most closely examined in cat cortex, all of the observations in monkey were consistent with those described in cat.
We have been fortunate in securing the cooperation of several colleagues who have contributed chapters, each dealing with one aspect of the subject. The analysis of visual space by the lateral intraparietal area of the monkey: the role of extraretinal signals. Individual dendrites serve as logical comparators of target location and eye position. This includes avoiding predators and dealing with conspecifics. Unconscious fear influences emotional awareness of faces and voices. Responses of monkey inferotemporal units in the orientation discrimination task.
The different periods of stronger gamma oscillations provide neurophysiological evidence that is consistent with other studies indicating that primates can detect snakes very rapidly and also cue in to faces for information. Long-term changes in visual mechanisms following differential stimulation of colour and luminance channels during development. The monkey chair was equipped with a responding button, which was positioned so that the monkey could easily manipulate it. These results strongly suggest that features of snakes are important to induce gamma oscillation. Original papers on this subject are numerous and widely scattered over many branches of science; it was felt that these papers should be reviewed and the knowledge brought together in one volume before it became too unwieldy. Animals must be able to navigate the biotic world in order to survive and reproduce successfully. Unilateral removal of all known visual cortical areas in the cat renders the animal hemianopic in the contralateral visual field as measured by visual perimetry and other behavioral tests.
