The shape and size of the brain varies greatly between species, and identifying common features is often difficult. Brain tissue in its natural state is too soft to work with, but it can be hardened by immersion in alcohol or other fixativesand then sliced apart for examination of the interior. Visually, the interior of the brain consists of areas of so-called grey matterwith a dark color, separated by areas of white matterwith a lighter color.
Can you see through these real-life optical illusions? Brain chemistry or neurochemistry is the complex system which allows the brain to function with the use of chemicals known as neurotransmitters which move information around in the brain.
It is believed that variations in brain chemistry may explain a variety of behavioral disorders and phenomena. The brain is a network of specialized cells called neurons. Each neuron has reserves of neurotransmitters which it can fire when ordered to so, along with receptors for specific neurotransmitters.
Brain Brain chemistry is created by sending messages with neurotransmitters to signal various cell activities throughout the brain and nervous system. Some chemical compounds appear to have long term effects.
Nicotinefor example, is heavily involved with the neurotransmitter dopamine. These external influences on chemistry in the brain can cause behavioral changes or alterations in the way the brain functions; people who smoke, for example, form an addition to cigarettes as a result of the way in which nicotine changes brain chemistry.
Ad Some people also appear to be prone to alterations in their brain chemistry which can occur as the result of genetic or internal functions.
These medications act differently on different people because the chemistry of the brain is very complex and varied, making it difficult to formulate a one size fits all medication to treat conditions like depression.
Certain personality types have also been linked with the levels of various neurotransmitters and receptors in the brain. Risk takers, for example, often have fewer dopamine receptors in their brains, which can mean that they have to work harder for a sense of satisfaction and reward.
This may push them to engage in risky behaviors. Changes in brain chemistry do not just affect mood.
They can also have a larger impact on the nervous system, which means that people can develop conditions such as tremors and neuralgia as a result of an alteration to the fundamental chemistry of the brain.Science in the News Opening the lines of communication between research scientists and the wider community What we do know, however, is that much of love can be explained by chemistry.
So, if there’s really a “formula” for love, what is it, and what does it mean? Brain scans of people in love have actually shown that the primary.

Brain Chemistry Labs' Movie Selected for Newport Beach Film Festival It was a successful world premiere of the documentary Toxic Puzzle, featuring Brain Chemisty Labs’ Paul Alan Cox, his team in Jackson Hole and collaborators from around the world.
Brief Description. The human brain is the most complex organ in the body—you need it to drive a car, to enjoy a meal, to breathe, to create an artistic masterpiece, and to enjoy everyday activities.
