Scientists led by Baylor University expert Joaquin Lugo, PhD, say that they have recently made significant progress in understanding how neurological disorders such as epilepsy affect the brain.
Their work was carried out on unsuspecting lab mice that were bred so that they lacked potassium channels on their neuron... |

University of California in Riverside (UCR) investigators say they may have discovered a new target for drugs in treating a neurodegenerative form of dementia called Alzheimer’s Disease. The molecule they discovered could also be targeted in the fight against other neurological disorders.
During the study, th... |

A team of experts based at the University of Michigan (U-M) argues that a new study carried out on lab rats has finally revealed the neural pathways fear uses to return to the brain, even after having been suppressed through behavioral approaches.
The reason why this study is important is that all behavioral therap... |

In a new study University of Oregon investigators conducted on lab rats, the team revealed that experiential learning is indeed the best way to imprint solid, long-duration memories into the brain. This finding could have significant implications for the human brain as well, since rats were used because they are such... |

Investigators in the United Kingdom, at the University of Bristol, say that they were recently able to identify a neural protection mechanism that acts during the onset of stroke. Its actions help protect certain types of neurons from the effects of this dangerous event. Using the new data, the team argues, it may be... |

According to the conclusions of a new study conducted on unsuspecting lab mice, it would appear that the timing of when the neurotransmitter acetylcholine is released in the brain is critical for understanding diseases such as Alzheimer’s and schizophrenia. This chemical is usually released in the hippocampus, ... |

Neuroscientists at the University of California in Berkeley (UCB) say they now know the neural pathways that fear uses to burn memories into our brains. The work holds promise for developing methods of allowing people to forget traumatic events and experiences. The fact that extremely stressful situations sear themse... |

Scientists have determined that neurons developing in an area of the brain called the hippocampus have a positive effect on mood and cognition. The correlation is especially true if the new nerve cells are acquired during adulthood. The investigation that led to this conclusion was conducted on unsuspecting lab mice,... |

Sleep researchers at the University of California in Berkeley (UCB) say they may have found an explanation for why people's brains tend to remain in a light, restless type of activity during a large portion of the time they are asleep, rather than going into REM.The rapid-eye-movements (REM) stage is considered ... |

Scientists now believe that memories can be protected more easily from interferences by reactivating them during sleep. For example, if you want to remember a song, you could listen to it while awake, and then someone would play it back to you during sleep. This would ensure the memory is firm.Investigations have dem... |

For some time now, healthcare experts have been using a therapy called deep-brain stimulation (DBS) for addressing some of the most stubborn neurological and neuropsychiatric conditions. In a new study, experts managed to determine which neural pathways respond to the electrical therapy.In this treatment, slender ele... |

Scientists at the Center for the Neurobiology of Learning & Memory recently managed an important breakthrough, when they were able to gain important new information on a portion of the brain known as the perforant path. The team, which is based at the University of California in Irvine (UCI), says that this cortical ... |

Experts investigating the way in which our brain forms, stores and recalls memory were recently able to demonstrate through imaging techniques that these events leave a trace in the cortex. The real finding is that this trace can be viewed with existing equipment. The discovery could lead to a better understanding of... |

Researchers from a Swedish university have recently demonstrated a clear connection between the number of instances in which children received anesthesia and their ability to learn new things. It would appear that this cognitive function is considerably impaired by the chemical cocktails that make up anesthesia drugs... |

It would appear that the advices many parents give their children, of sleeping for a couple of hours in the afternoon each day, are actually founded in some solid science. According to a new research, napping in the afternoon may be a foolproof way of consolidating memories, and also of clearing your mind of excess i... |

Though scientists still have no clue why we need to sleep, if we don't, there are always consequences. One of the most severe is the fact that our memory is left in tatters and that we lose our ability to concentrate on the tasks at hand throughout the next day. Now, researchers hope to counteract some of these ... |

Understanding exactly how we learn and remember has been a long-standing goal in science for many years, but investigations into the issue have thus far yielded inconclusive and contradictory results. Recently, a new study conducted on rats has revealed a new aspect of the problem. The team of investigators, from the... |

For many years, researchers have been wondering if the human brain grows neurons once it reaches adulthood, or whether the number of brain cells we're born with is the maximum we'll ever get. Once it was established that we, indeed, grew new neurons as we got older, the debate has moved over what purpose th... |

Researchers have known for quite some time now the basic mechanisms associated with fear, as in what triggers it, and how it is encoded in the brain. But now, a new line of investigations has revealed the exact location in the brain where the feeling is stored, and the region is called the amygdala. The experiments t... |

Experts at the Massachusetts Institute of Technology have demonstrated in a new mouse-model study that the animals that are prevented from remembering data collected during the day while sleeping tend to have “fuzzy” memories the next day, as opposed to mice who were left to sleep undisturbed. The researc... |

For quite some time now, experts have wondered how exactly it is that the human brain is able to store memories of single events, and to recall them at a moment's notice. Over the years, they have noticed that the emotional response this type of memories draws from people is almost identical to the one incited b... |

People often take for granted traits of their brain that have had experts puzzled for generations. That is to say, for example, they don't know exactly how the part of the cortex that deals with memory operates when they need to find the car they parked in a very busy supermarket parking lot. The scientists also... |

In most people, their most powerful memories are those of a single event, such as a birth, a funeral, a death, a birthday party, a wedding proposal, and so on. And while everyone knows this, scientists have found it close to impossible until now to understand what exactly is going on inside the brain that allows them... |

Memory is still one of the most mysterious processes of the brain. Now, another piece in the complicated puzzle has been located: while sleeping, the reactivated memories of real-time experiences are reviewed in high "thought speed", 6-7 times more than in wake time, by the brain. Memory is kept in modules in the bra... |

Folk wisdom shows that if you're dumb, you'll get dumber. And indeed, if the brain is already teaming with information, the new one will stuck very quickly. This is the conclusion of a research made on rats that could help explain human learning.The research team trained lab rats to link six feeding spots w... |

Indeed, too much of anything, even if it can seem good on one side, can occult another side. A new investigation made at Columbia University Medical Center was able to explain why people possessing a vast amount of scientific knowledge, recalling historical dates or long-ago events may find it hard to recall what the... |
