Development of functional connections between thalamic fibres and the visual cortex of the wallaby as revealed by current source density analysis in vivo.
Functional development of thalamic input to the cortex in anaesthetised wallaby pouch young between postnatal day 25 (P25) and P153 has been studied by electrical stimulation of the optic nerve, current source density (CSD) analysis, and histologic identification of recording sites. Conduction in the optic nerve was recorded prior to P39, by which time responses from the superior colliculus appeared. No evoked potential of cortical origin was recorded until P46, even though thalamic fibres grew...[Show more]
