Scientists at the Sloan Kettering Institute say that they have recently developed a new method for growing a special type of neurons. They add that these cells could be used to counteract the negative effects of Parkinson's disease on the human brain.
In a new series of experiments, experts develop a method fo... |

Bulimia acts insidiously on the human brain, by hindering the correct firing of neurons in the cortex's reward circuitry. As such, people who suffer from the condition do not experience the correct rewards provided by the neurotransmitter dopamine when reward-worthy actions are completed. This is one of the firs... |

Investigators attending a conference yesterday heard a new theory on the causes that lead to the development of Parkinson's disease. A team of scientists proposes that the condition may be at least partially caused by a type of bacteria known to be responsible for stomach cancer and ulcers. The new study indicat... |

The brains of drug addicts and binge eaters share a number of mechanisms in common, researchers argue in a new study. The paper reveals how the brains of binge eaters are primed to experience rewards similarly to how drug addicts do, when they are exposed to the sight or smell of food. The way this is done, the scien... |

As evidenced by many studies, one of the main things promoting addiction is dopamine. High-risk drugs such as cocaine and heroin act on this neurotransmitter, which is absolutely essential to our happiness.

Producing the neurotransmitter dopamine outside the brain is one of the main goals in medicine today, but devising setups for this, as in creating dopamine-producing neurons, has proven to be extremely difficult. Now, this goal may be one step closer to reality, thanks to a new study by experts at the Swedish medical... |

In laboratory conditions, researchers test various aspects of lab rats' behavior, in a bid to find parallels between their way of acting in certain situations and our own. Once this happens, they find an animal model for a certain human trait, various aspects of which they can analyze. In a recent investigation,... |

Each of our brains is endowed with a type of memory known as "working memory," which is responsible with storing short-term data. This function allows us to resolve problems, to understand readings, and to be able to memorize fairly small bits of information to be used after a short time. Identifying it is simple, an... |

The research inside the causes of schizophrenia is a very complex one, scientists agree, as there are many areas of the brain that are involved in the onset and development of the disease, as well as many neurotransmitters that act on those regions, such as dopamine and glutamate. That's why the orbitofrontal co... |

Teens may become hooked on cocaine and, once rehabilitated, relapse more rapidly than adults because their developing brains are more sensitive to drug-related cues. At least in the case of rats, this holds true. A new study carried out at McLean Hospital, the largest psychiatric facility at Harvard Medical School, a... |

There is a large array of studies focusing on how cocaine impacts the brain creating addiction. The main investigated mechanism has been the effect of cocaine on dopamine (the feel good or reward hormone) and dopamine transporters, proteins that reabsorb this neurotransmitter once it has sent its signal. Cocaine is k... |
