Developmental alterations in the functional properties of excitatory neocortical synapses

D Feldmeyer, G Radnikow - The Journal of physiology, 2009 - Wiley Online Library
In the neocortex, most excitatory, glutamatergic synapses are established during the first 4–5
weeks after birth. During this period profound changes in the properties of synaptic …

Canadian Association of Neurosciences review: postnatal development of the mammalian neocortex: role of activity revisited

Z Zhang - Canadian journal of neurological sciences, 2006 - cambridge.org
The mammalian neocortex is the largest structure in the brain, and plays a key role in brain
function. A critical period for the development of the neocortex is the early postnatal life …

Properties of excitatory synaptic connections mediated by the corpus callosum in the developing rat neocortex

SS Kumar, JR Huguenard - Journal of Neurophysiology, 2001 - journals.physiology.org
Despite the major role of excitatory cortico-cortical connections in mediating neocortical
activities, little is known about these synapses at the cellular level. Here we have …

[PDF][PDF] Synaptogenesis in human cerebral cortex and the concept of critical periods

PR Huttenlocher - The role of early experience in infant development, 1999 - Citeseer
The cerebral cortex is an extremely complex information-processing system. Histologically, it
consists of six fairly distinct horizontal layers, each with unique functions. These include …

Activation of early silent synapses by spontaneous synchronous network activity limits the range of neocortical connections

T Voigt, T Opitz, AD de Lima - Journal of Neuroscience, 2005 - Soc Neuroscience
During the early development of neocortical networks, many glutamatergic synapses lack
AMPA receptors and are physiologically silent. We show in neocortical cultures that …

Developmental switch in the short-term modification of unitary EPSPs evoked in layer 2/3 and layer 5 pyramidal neurons of rat neocortex

A Reyes, B Sakmann - Journal of Neuroscience, 1999 - Soc Neuroscience
Amplitudes of EPSPs evoked by repetitive presynaptic action potentials can either decrease
(synaptic depression) or increase (synaptic facilitation). To determine whether facilitation …

Release kinetics, quantal parameters and their modulation during short‐term depression at a developing synapse in the rat CNS
