✦ Synopsis

Recently, a role for neurotrophins in regulating cortical developmental plasticity has clearly emerged. We present in this review a summary of the early data on the action of nerve growth factor (NGF) in visual cortical development and plasticity in the rat and of other neurotrophins in the visual cortex of other mammals. In addition, to clarify the differences in the results obtained with the various neurotrophins in different animal preparations, we also report new data on the action of NGF, brain-derived neurotrophic factor (BDNF), neurotrophin (NT)3, and NT4 in the same preparation-namely, the visual cortex of the rat. We discuss old and new results in a physiological model in which different neurotrophins play different roles in regulating visual cortical development and plasticity by acting on different neural targets, such as lateral geniculate nucleus (LGN) afferents, intracortical circuitry, and subcortical afferents, and propose a tentative scheme summarizing these actions.

We have investigated the postnatal development of N-methyl-D-aspartate (NMDA) receptors in kitten neocortex by measuring the density of [3H] MK801 binding sites. NMDA receptor density in area 17 markedly increases between postnatal day 7 and 35, and then remains at a high level into adulthood. Simil

It is widely accepted that functional maps in the mammalian visual cortex such as ocular dominance columns and orientation columns are formed depending on neural activity. There is still, however, controversy on how much visual experience contributes to the map formation during development. In the p

## Abstract Electroencephalography (EEG) signals have been an attractive choice to build noninvasive brain computer interfaces (BCIs) for nearly three decades. Depending on the stimuli, there are different responses which one could get from EEG signals. One of them is the P300 response which is a v
