Stories about: visual cortex |

City College of New York investigators, led by neuroscientists Tony Ro, are currently working on a new method of restoring sight to patients who went blind following accidents that damaged the visual cortex at the back of their brains.
In this population, the eyes and optical nerves are intact, and produce electric... |

Our perception of colors – while pretty good on some occasions – is entirely lacking on others. Researchers highlight two so-called “forbidden colors” that our eyes cannot see due to the very nature of how we perceive colors.
The colors are reddish green and yellowish blue. Just to make matt... |

Investigators from the Boston University (BU) and the ATR Computational Neuroscience Laboratories, in Kyoto, Japan, say that it may be possible to soon use a new technology for boosting visual perceptual learning, or even healing mental damage.
This could be done with little or no conscious effort on the part of th... |

A new study confirms and expands upon past proposals that the human brain may in fact be a lot more flexible than thought. The investigation revealed that the brain areas responsible for processing various stimuli can be recruited to perform other functions, if their primary one cannot be satisfied. Generally, the br... |

A team of neuroscientists at MIT and Harvard found that the same face can look male or female to a person, depending on where it appears in his/her field of view.If we are surrounded by people, we can tell usually who is a man and who is a woman, by looking at their clothes, or at their hair.This actually proves that... |

In a groundbreaking new study, researchers have finally been able to map the distribution of signals in the neural circuity that connects individual photoreceptor cells with retinal ganglion cells.The former type are the ones responsible for carrying electrical signals from the eye to the brain. The retina is the par... |

Endowing computers with artificial vision is something that robotics experts have been after for a long time. However, this is a very complex task that has left many research teams puzzled over how to defeat the numerous challenges ahead. Now, researchers at the Harvard University and the Massachusetts Institute of T... |

When people go blind, they lose one of the most important senses an individual can have. Single-handedly, sight accounts for the usage of massive amounts of processing power inside the brain. When the sense vanishes, the brain is left with a lot of “computing hours” to spare, and scientists at the Univers... |

It's a widely known fact that the brain, while indeed collecting all the stimuli it sees around us, only presents us with a minor fraction of those stimuli that spring into our conscious mind. When taking this into account, we are, in a sense, partially blind even before a doctor gives the verdict. A new scienti... |

According to a new scientific study, it may be that the sound of approaching footsteps makes us more efficient at seeing in the dark. The process of boosting the visual acuity takes place even before we can consciously make out the sounds, a team of scientists from the University of Glasgow reports. The experts hypot... |

Scientists at the Washington University School of Medicine (WUSM) have recently been able to determine that the “white noise” our brains make changes considerably once we start learning new things, hinting at the fact that it helps reshape the neural connections that allow us to memorize new information. ... |

Tests conducted on blind patients brought hope to the scientific community, when new-generation retinal implants proved to be extremely effective in returning at least partial sight to patients who could not see at all. The test participants were able to recognize large objects and obstacles, and one of them was also... |

An international team of scientists has recently made a groundbreaking discovery, when experts have discovered that people who were partially blind, due to injury to half of their brains, were able to “see” facial expressions and body language in pictures of other individuals. All of the images were shown... |

Being wary of dangers is, arguably, one of the things that allowed our once-fragile species to become strong enough to take over the planet. Our ancestors developed a large number of reflex and pattern-recognition connections in their brains, in order to maximize their chances of survival. But experts have always bee... |

The human brain is responsible for analyzing, or integrating, all of the five established senses that each of us has. When each of these senses is activated, changes were previously proven to occur in the cortex, which modifies itself so as to ensure that we perceive events on the outside as accurately as possible. R... |

The human brain's ability to focus on an important issue, process, or decision, while ignoring everything else has puzzled neuroscientists for a long time, who could not understand how this mechanism worked. They had a few hints as to the brain regions involved in the process, but concrete scientific pieces of e... |

Conventional wisdom until now held that the brain entered a state of “hibernation” while sleeping, and that the senses could be activated only by outside stimuli, or by the body's internal clock. This explanation of the electrical activity registered among neurons during sleep now seems to be a bit o... |

Duke University researchers managed to take a giant step forward when their experiment, focused on observing exactly how vision develops in simple brains, succeeded. The team observed the changes a ferret's brain underwent after it first opened its eyes, 30 days from its birth. The way in which neurons arranged ... |

It is well known that MRI scanners can be currently used to probe inside the human brain, and other living beings for that matter, in order to determine the pattern of brain activity and correlate what will actions the respective being is performing at a given moment. However, scientists want more than the identifica... |
