PubMed - Effects of ethanol on the development of circadian time keeping system - Abstract: Ethanol exposure during gestation can have devastating consequences on the developing organism. Children who have a history of prenatally exposure to ethanol may show morphological and functional alterations, referred to as fetal alcohol spectrum disorders (FASD). Fetal alcohol syndrome (FAS), which is characterized by pre- and postnatal growth deficiency, specific cranial/facial features, and dysfunction of central nervous system, is the most severe end of FASD
University of Bristol - MRC Centre for Synaptic Plasticity - Glutamate Receptors - Glutamate is the major excitatory neurotransmitter in central nervous system (CNS) and as such the glutamate receptors play a vital role in the mediation of excitatory synaptic transmission -
In the new study, researchers led by Maiken Nedergaard, M.D., D.MSc., of the University of Rochester , showed that glutamate produced by astrocytes can trigger seizures.
"The focus of the study is on the plentiful neurons that communicate with each other through the neurotransmitter glutamate. While glutamate is a necessary excitatory substance in the nervous system, in excess, it overstimulates and becomes toxic - excitotoxic - to neurons. Fortunately, neighboring astrocytes can mop up the excess via molecular transporters embedded in their outer membranes. The chief transporter is a protein called EAAT2.
Earlier Rothstein's group showed that astroglia - and their EAAT2 protein -
are critical for normal neuron activity. In test rats whose astroglia lack the
EAAT2 equivalent there's not only a flood of toxic glutamate but a resulting
neuron death that leads to paralysis."

NINDS - Researchers Identify a Signal for Cell Death during Stroke - In a new study, researchers have identified a signal that promotes the death of vulnerable brain cells in an animal model of stroke. In the future, drugs designed to inhibit this death signal might help reduce brain damage in stroke patients
