This book looks in detail at human mast cells. It includes a review of previous and current
ultrastructural studies, whereby the latter are illustrated with numerous high-quality electron …

Spike-timing-dependent plasticity (STDP) is found in vivo in a variety of systems and
species, but the first demonstrations of in vivo STDP were carried out in the optic tectum of …

Much of the information processing in the brain occurs at the level of local circuits; however,
the mechanisms underlying their initial development are poorly understood. We sought to …

The integration of multisensory information takes place in the optic tectum where visual and
auditory/mechanosensory inputs converge and regulate motor outputs. The circuits that …

Light-induced calcium influx into retinal axons is regulated by presynaptic nicotinic
acetylcholine receptor activity in vivo. Visual activity is thought to be a critical factor in …

We have used anatomical methods and whole-cell patch-clamp recording to assess the
distribution of nicotinic receptors in the tectum of Xenopus frogs and to measure effects of …

Amphibian metamorphosis is a transitional period that involves significant changes in the
cell-type populations and biological processes occurring in the brain. Analysis of gene …

Xenopus frogs exhibit dramatic changes in the binocular projections to the tectum during a
critical period of development. Their eyes change position in the head, moving from lateral to …

The spatiotemporal sequence of the appearance of cholinergic structures in the brain of
Xenopus laevis during development was studied by means of choline acetyltransferase …
