In Parkinson's disease up to 80 percent of the neurons that produce a chemical called dopamine which controls muscle function are damaged according to the National Parkinson Foundation.

#Making Maps In The Brain (ISNS)--Disorientation is often one of the first warnings of Alzheimer's disease.
Now neurologists offer a clue as to why the first kind of memory to fade may be navigational.
Researchers at Emory University near Atlanta have demonstrated that primates map their environment using grid cells specialized neurons that help the animals navigate by overlaying a virtual grid made of triangles atop regularly spaced points in the environment.
Elizabeth Buffalo the study's lead author is an associate professor of neurology at Emory University School of medicine.
She suspects that these grid cells don't just help primates navigate--they also help form visual memories.
And because of their location in the brain they are especially susceptible to the ravages of Alzheimer's.
   Grid cells were identified for the first time in 2005 by a group of scientists in Norway interested in how the brain enables animals to navigate.
and monitored individual neurons while the rats explored. The neurons they were watching lie in a part of the brain called the entorhinal cortex.
It sits in the lower part of the brain near its intersection with the brain stem. This is the perfect position for a mapmaker:
the entorhinal cortex gets input about the environment from the senses and sends its output up to the hippocampus
which is known for its roles in memory and navigation. Â As a rat walked around the enclosure a neuron in the entorhinal cortex fired;
the rat walked a little more and the neuron fired again. When the team mapped out all the points in the enclosure that had lit up a particular neuron they found that these weren't just random signals:
those hot spots defined a grid of equilateral triangles laid side by side. The grid produced by each grid cell can serve as a basic map where the hot spots are like signposts.
By arranging these signposts in triangles the brain can fit in more of them than it could
if they were the same distance apart but arranged in rectangles. Grid cells are distributed irregularly in the entorhinal cortex
and each one produces a slightly different grid. These grids overlap to generate a high-resolution map of the entire environment.
In humans the entorhinal cortex is one of the first areas to degenerate in Alzheimer's disease.
While experiments using functional magnetic resonance imaging had hinted at the presence of human grid cells they had never been observed directly in any primate.
while tiny microelectrodes monitored neurons in the entorhinal cortex. When Buffalo and her coworkers compared eye-tracking results to the electrode measurements they found that the monkeys like the rats were using neurons in the entorhinal cortex to construct a triangular grid they could superimpose on their environment.
 Primates though are sophisticated more cartographers: the monkeys were able to activate their grid cells simply by looking around.
which animals construct their visual memories. That has important implications. One of Buffalo's research interests is the early diagnosis of neurodegenerative diseases.
Studies of brain changes in Alzheimer's disease in humans consistently show localized degeneration in the same parts of the entorhinal cortex where Buffalo found grid cells in monkeys.
May-Britt Moser one of the authors of the original Norwegian study described Buffalo's results as extremely exciting.

Flavor is a combination of input to the brain from the taste buds and from the nose.
Yet it combines with the input from other volatiles as well as input from the taste buds to create the perception of sweetness in the brain.
No one knows exactly how volatiles create perceptions of sweetness in the brain. It's possibly as simple as volatiles intensifying the effect of sugars in the brain said Bartoshuk in an interview with My Health News Daily.
Not all volatiles contribute to sweetness either. In fact Bartoshuk believes that some may actually suppress sweetness.
