Brain development

Many chemicals cause a decrease in brain size during fetal development. Changes in brain size can be caused in various ways. A decreased brain weight may be a consequence of general undernutrition caused by effects on placental functioning. Examples of other possible mechanisms are inhibition of cell multiplication or cell growth, increased cell death, disrupted trophic effects induced by changes in cell maturation and neurochemistry. [Pg.279]

Changes in brain structure can occur in many different ways. For instance, neuronal death or disruptions in neuronal maturation (see also section 3.2), differentiation (see also section 3.7), migration, synaptic formation, glial and neurochemical development (see also section 3.4), can all have effects on brain structure. [Pg.280]


It is known that the brain is one of the most sensitive sites of action of steroids in utero, and recently there have been suggestions that EDs may affect normal brain development and behaviour. For example, it has been alleged that in utero exposure to polychlorinated biphenyl compounds (PCBs) resulted in adverse effects on neurologic and intellectual function (memory and attention) in young children born to women who had eaten PCB contaminated fish in the USA." It has also been speculated that exposure to environmental pollutants with steroidal activity may be infinencing human sexual development and sexually controlled behavioiir." ... [Pg.7]

Mammals lack the ability to synthesize astaxanthin or convert dietary astaxanthin into vitamin A. Unlike p-carotene, astaxanthin has no pro-vitamin activity in these animals. Astaxanthin has been shown in both in vitro and in a study with human subjects to be effective for the prevention of the oxidation of low-density protein, suggesting that it can be used to prevent arteriosclerosis, coronary artery disease, and ischemic brain development. A number of astaxanthin health products are under study. [Pg.407]

The brain allowed greater and greater use of the environment since it, unlike the genes, had information from the environment, made useful in a rapid operational way and hence made possible environmental control by organisms. The brain developed its own coded information. [Pg.458]

Adhesion molecules are indispensable components of nervous tissue. They adhere cell membranes to each other with varying degrees of strength and translate adhesion into cellular responses via signal-transduction pathways (see, for example, [45]). The major classes of adhesion molecules, the integrins, IgCAMs and cadherins, act cooperatively [46] and in concert to coordinate brain development and maturation and, in adulthood, to maintain the normal tissue architecture. [Pg.119]
