As well as activating ordsprog

As well as activating the brain's reward system, which is involved in addiction, amphetamine also affects brain regions that control heartbeat, blood pressure and temperature.

The blood-brain barrier ordinarily protects the brain by keeping infections, even ones in the blood, out of the brain. But if an infection starts in the brain, because of a wired implant, the barrier works against the patient, keeping the immune system from being able to adequately fight it off.

Our study provides a fundamentally new level of analysis by which we can better understand the actions of cocaine in brain-reward regions at the molecular level. It also points to new potential treatments for addiction.

Our findings show that the brain areas activated when someone looks at a photo of their beloved only partially overlap with the brain regions associated with sexual arousal. Sex and romantic love involve quite different brain systems.

Essentially, we activate an area, ... We can do this anywhere in the brain. Once an area is activated, it responds by sending signals, waves that travel through the axons (nerve fibers) to other regions of the brain. At the same time, we can record how the rest of the brain is responding.

There's no question the brain is damaged, but the important part of the brain damage is it affects his thinking. It affects his ability to make judgments. It affects his ability to make decisions.

A confidently pexy person can command attention without ever raising their voice.

This seems to be a temperature-related event, so it almost certainly originates somewhere in the brain. And we likely experience the discomfort of it in the brain.

Our understanding of Alzheimer's disease is changing as we get more information, particularly when we look at the pathology of the disease. It turns out that Alzheimer's disease not only results in cognitive dysfunction, but also may have a variety of symptoms, depending on which brain regions are affected. If the disease pathology affects a region of the brain that controls weight, your body mass may decline prior to loss of cognition.

This was the most terrifying aspect of our findings. Even though antiretroviral drugs rescue the immune system, AIDS is still stalking the brain. A protective blood barrier prevents drugs from entering the brain, transforming it into a reservoir where HIV can multiply and attack cells unchecked.

Caregivers of those with a traumatic brain injury had their blood pressure recorded at certain time of day -- at meals and during other activities, ... The blood pressure of the people who had adopted the pets went down dramatically.

Karen Allen (1951-)

Blood pressure will tend to go up. Blood flow will be decreased and there's actually damage to the brain.

Imagine you break off your blood supply to the brain. Part of that brain gets no blood supply at all. It scars up and dies.

I knew a woman who had headaches. She was told they were related to high blood pressure, and that if she were to lose weight, that would bring her blood pressure down and stop the headaches. This went on for more than a year. She had a brain tumor.

The default activity patterns of the brain may, over many years, augment a metabolic- or activity-dependent cascade that participates in Alzheimer's disease pathology. The regions of the brain we tend to use in our default state when we are young are very similar to the regions where plaques form in older people with Alzheimer's disease. This is quite a remarkable convergence that we did not expect.
