Human infants’ ability to perceive touch in external space develops postnatally

Arriving in the outside world, the newborn infant has to determine how the tactile stimulation experienced in utero relates to the spatial environment newly offered up by vision, hearing and olfaction. We investigated this developmental process by tracing the origins of the influence of external spatial representation on young infants' orienting responses to tactile stimuli. When adults cross t...

Emergence of the ability to perceive dynamic events from still pictures in human infants

The ability to understand a visual scene depicted in a still image is among the abilities shared by all human beings. The aim of the present study was to examine when human infants acquire the ability to perceive the dynamic events depicted in still images (implied motion perception). To this end, we tested whether 4- and 5-month-old infants shifted their gaze toward the direction cued by a dyn...

Mouse Ability to Perceive Subjective Contours.

In contrast to the previously held notion that mice have a weak visual system, it is now generally accepted that mice can perceive rather complicated figures in various contexts such as in cognitive experiments and in social settings. Here, we show that mice could even be capable of perceiving a visual illusion--subjective contours. This illusion requires the visual system to compensate for a l...

The Posterior Parietal Cortex Remaps Touch into External Space

Localizing tactile events in external space is required for essential functions such as orienting, haptic exploration, and goal-directed action in peripersonal space. In order to map somatosensory input into a spatiotopic representation, information about skin location must be integrated with proprioceptive information about body posture. We investigated the neural bases of this tactile remappi...

The subarachnoid space develops early in the human embryonic period.

The anlage of the subarachnoid space is seen in embryos at stage 14 (33 days) in the innermost zone of the primary meninx as irregular spaces on the ventral surface of the spinal cord. At first this space is only on the ventral surface of the spinal cord. From stage 18 (44 days) on, when the dura mater proper is formed, the reticular tissue of the primary meninx and spaces are around the circum...
