At the time of the shooting, Ruby said he was taking phenmetrazine, a central nervous system stimulant.

The altered parts of the nervous system might keep generating injury messages, even after the original injury has healed.

Scientists have bred worms with genetically modified nervous systems that can be controlled by bursts of sound waves.

While these deficiencies may not be prompting clinically adverse effects, they may be sufficient to impair fetal neurodevelopment.

An important step is to improve our ability to determine which chemicals have neurodevelopmental effects.

Microcephaly is a neurodevelopmental disorder in which the head circumference of newborn babies is smaller than usual.

Cells The nervous system contains two main categories or types of cells neurons and glial cells.

But the nervous systems of fish are sufficiently similar to those of birds and mammals to suggest that they do.

They understand the structural integrity of a deep avuncular lap, as compared to the shaky arrangement of a neurotic niece in high heels.

Now this is the part of the nervous system that deals with the things that we don't consciously control, like digestion, heart rate and sexual arousal.

They are named for their resemblance to neuronal dendrites, as both have many spine like projections, but dendritic cells are in no way connected to the nervous system.

Results of Kurrasch s latest study investigating neurodevelopmental effects of BPA illustrate what she means.

She and her colleagues are investigating, not only associations between exposures and neurodevelopment, but also the mechanisms by which effects occur.

Scientists are currently investigating whether the Zika virus is also linked to the nerve disorder Guillain Barré, which can cause paralysis.

Military overreach has predictably led to nervousness about using military power, and others knowledge of this threatens to weaken America s security as well. But America s real strength, more than its military and economic power, is its soft power, its moral authority.

Now, this doesn't have a brain, it doesn't have a neural system. This is just a sack of chemicals that is able to have this interesting and complex lifelike behavior.

Military overreach has predictably led to nervousness about using military power, and others knowledge of this threatens to weaken America s security as well.

For example, nerve cells are produced in excess, and some die in order for proper connections to be established in the nervous system.

Television is attractive to the architecture of the human nervous system our brains are built to absorb information and follow rapid changes in the sensory field.

Seemingly lacking a central nervous system, it has become a dysfunctional creature with little capacity to recognize any common national, much less international, interest.

Research increasingly suggests that airborne contaminants can have subtle but significant effects on early neurological development and behavior, she says.

The parasympathetic nervous system (abbreviated PN to avoid confusion with the peripheral nervous system (PNS)) is one of the two divisions of the autonomic nervous system, the other being the sympathetic nervous system.

Research increasingly suggests that airborne contaminants can have subtle but significant effects on early neurological development and behavior.

Just as giving to someone in need elicits a positive neural response, so does taking from someone who deserves it.

The attenuated poliovirus in the Sabin vaccine replicates very efficiently in the gut, the primary site of wild poliovirus infection and replication, but the vaccine strain is unable to replicate efficiently within nervous system tissue.

Chemicals in flame retardants, plastics, and personal care and other household products are among those Lanphear lists as targets of concern for their neurodevelopment effects.

An increase in sympathetic nervous system stimulation causes the heart rate to increase, both by the direct action of sympathetic nerve fibers on the heart and by causing the endocrine system to release hormones such as epinephrine (adrenaline), which have a similar effect.

Many chemical mediators are involved, including cortisol and adrenalin from the adrenal glands, other hormones and neurotransmitters (such as serotonin and noradrenalin), and responses from the autonomic and immune systems.

In its earliest form, the brain appears as three swellings at the front end of the neural tube these swellings eventually become the forebrain, midbrain, and hindbrain (the prosencephalon, mesencephalon, and rhombencephalon, respectively).

If true, then the best way to understand how the fear system works is not to chase the elusive brain mechanisms of feelings of fear, but to study the underlying neural systems that evolved as behavioral solutions to problems of survival.

In Europe, mad cow disease shocked many people, not only because it shattered beef s image as a safe and healthy food, but also because they learned that the disease was caused by feeding cattle the brains and nerve tissue of sheep.
