“…Therefore, in these cats the maximal disparity increased, and reached fairly large angles towards the end of the rearing period, when the kittens' heads would sometimes touch the ceiling. Cooper, 1970;Hirsch & Spinelli, 1971;Stryker et al 1978). However, this hypothesis is difficult to reconcile with our data.…”

SUMMARY1. The different perception of vertical in the two eyes (Helmholtz, 1864) was interpreted as an adaptation of cortical binocular receptive fields to the bias distribution of orientation disparity in the visual environment resulting from the relative frequency of contours in horizontal planes below eye level (ground, table) compared to other orientations in space.2. Kittens were reared in environments where visible contours were confined to a horizontal plane which was the floor for two kittens and the ceiling for two other kittens. The floor tended to produce negative, the ceiling positive, orientation disparities. In either case, the disparities were maximal about the vertical retinal meridians and zero at the horizontal meridian. The preferred stimulus orientations of binocular neurones in area 17 of the visual cortex were determined at 3-4 months age in these four kittens and in seven normal cats for control. Automatic stimulus variation, quantitative analysis, and eye drift correction were used.3. In the 'floor cats' neurones with near-vertical orientations showed a mean interocular angle between the preferred orientations of -8.70 relative to neurones with near-horizontal orientations; in the 'ceiling cats', the angle was + 2.8°; in the normal cats it was -0.40. 4. Since these angles are independent of the alignment of the eyes, the difference between floor cats and ceiling cats reflects different functional connexions at cortical level. This indicates that the orientations of the developing receptive fields can be modified by visual experience.5. These observations in kittens suggest that the perceptual difference between the eyes in man is also caused by early visual experience.

“…There is evidence showing that if visual, auditory, and tactile inputs never have the chance to occur together, there is no opportunity to develop an integrated linkage between what is seen, heard, and felt [4]. While a well-known supporting experiment was done on cats [5], similar results on human babies were also reported [6]. 4) Open-ended sensory stream: It has a beginning, but not an end.…”

Abstract-It is elusive how the skull-enclosed brain enables spatio-temporal multimodal developmental learning. By multimodal, we mean that the system has at least two sensory modalities, e.g., visual and auditory in our experiments. By spatio-temporal, we mean that the behavior from the system depends not only on the spatial pattern in the current sensory inputs, but also those of the recent past. Traditional machine learning requires humans to train every module using hand-transcribed data, using handcrafted symbols among modules, and hand-link modules internally. Such a system is limited by a static set of symbols and static module performance. A key characteristic of developmental learning is that the "brain" is "skull-closed" after birth-not directly manipulatable by the system designer-so that the system can continue to learn incrementally without the need for reprogramming. In this paper, we propose an architecture for multimodal developmental learning-parallel modality pathways all situate between a sensory end and the motor end. Motor signals are not only used as output behaviors, but also as part of input to all the related pathways. For example, the proposed developmental learning does not use silence as cut points for speech processing or motion static points as key frames for visual processing.

“…The development of the mammalian visual system is strongly dependent on e d y visual stimulation [ l l , 611. In particular, it is known that mammals raised in unusual image environments end up with functionally modified visual systems as adults [36]. This suggests that the visual system's development is influenced by the statistics of its environment, through some as yet unknown algorithm.…”

AbstracLRecently there has been a resurgence of interest in the properties of natural images. Their statistics are important not only in image compression but also far the study of sensory processing in biology, which can be viewed as satisfying cettain 'design criteria'. This review summarizes previous work on image statistics and presents our own data Perhaps the most notable property of natural images is an invariance to scale. We present data to support this claim as well 35 evidence for a hierarchical invariance in natural scenes. These symmetries provide a powerful description of natunl images as they g~d y resttiit the class of allowed d i s Vib ut ions.
