According to science journal Plos One the international team of researchers from Starlab Barcelona in Spain and Strasbourg successfully achieved brain-to-brain transmission of information between humans. For brain-to-brain transmission the researchers used electroencephalogram (EEG) and image-guided transcranial magnetic simulation technologies to transmit the greetings between test subjects from India to France in one study and from Spain to France in another.Electrodes were attached to a participant’s scalp on the emitter end.
Scientists created the most exact three-dimensional map of brain on which it is possible to make out separate neurons and their shoots. The map will help psychiatrists and other experts investigating the nature of mental disorders. The digital three-dimensional map of brain created on the basis of a brain of died woman. The map allows in 20 micrometers studying internal communications of neurons. By the words of founders of BigBrain from Germany and Canada, the map traced by 50 times more detail, than result of the previous attempt to create the similar map. The technique of scanning developed by leading German experts in this area, assumes cross division of a brain into a large number of layers the microtome. The microtome is the special tool intended for these purposes, and processing of cuts by the special solution, allowing to make cells of a brain more visible for computer devices. After that cuts are illuminated with help of the scanner, and the special computer algorithm unites these pictures in a whole.
Scientists created tiny implanted wireless LED devices, which delivered to experimental mice the mass of pleasure. Scientists from University in Saint Louis and University of the State of Illinois developed microscopic light-emitting diodes thinner, than a human hair. These light-emitting diodes can be implanted into any site of a body by means of a usual thin medical needle. Experiment essence is the following: at first gene engineers modified mice by means of technology of optogenetics, those are neurons of a brain on the light signal created by a tiny light-emitting diode “taught” to join and be switched off. Then closer to these neurons is implanted a light-emitting diode. Inclusion of a light-emitting diode activates neurons, and switching off on the contrary – deactivates.
Neurobiologists of Stanford University made nervous fabric of a rodent absolutely transparent, and by a usual light microscope in this transparent brain it is possible to consider the separate neurons, which are shining in the dark with yellow, red and blue fluorescent light. The brain has grayish-white color. This color results from multiple reflection of light on borders of cell membranes. To make nervous fabric invisible, reflection needs to be minimized. At first scientists tried to reach it by solutions of organic substances with specially picked up coefficient of refraction, such that on border of a cell membrane of reflection didn’t occur. Use of such solutions allowed to make nervous cuts transparent, but the method has essential shortcomings. Alternative way of an enlightenment of a brain there can be a full removal at cages of membranes.
The scientists of Cornell University discovered that it is possible to know, who a person is thinking about. It is possible by analyzing images of a brain of person. The team of scientists demonstrated, that the people’s mental models produce patterns of the activation of the brain. The team of scientists asked the participants to learn personalities of four different people. With the different scenarios, the 19 young adults were asked to imagine how the person can respond to the scenario.
Japanese neuroscientists have learned to anticipate the visual content of dreams. Results of their work, scientists reported on neurobiological conference in New Orleans. Experiments were carried out in blocks of three hours for a few weeks. Volunteers were placed in a scanner, where they were to sleep. Once in the brain, the experiment participants are beginning to have characteristic electrical activity of the onset of sleep, they woke and asked about the content of the dream. Within an hour, spends six to seven cycles of sleep and waking, but only one of the volunteers told about the content of their dreams about 200 times.
A Japanese company called Suidobashi Heavy Industries recently revealed its 13-foot mech robot named Kuratas. Kuratas is the brainchild of artist Kogoro Kurata and robotics researcher Wataru Yoshizaki. Kuratas can be controlled in three ways – either through a controller, a master slave, or an iPhone. The robot runs on an operating system called V-Sido and it is outfitted with a launcher and a twin Gatling gun.
A new sensory organ has been discovered in rorqual whales. Rorqual whales are a subgroup of baleen whales that includes blue, fin, minke, and humpback whales. They are known for their enormous size, and an accordion-like layer of blubber extending from their snout to their navel. This blubber can expand to many times its resting size, allowing massive quantities of prey-filled water to be swallowed and then expelled back out while filtering the prey.
Duke University Medical Center scientists have discovered a way to turn the scar tissue that forms after cardiac arrest into healthy muscle tissue, which would make a stem cell transplant unnecessary. To achieve this, Duke University Medical Center scientists introduced microRNA to scar tissue cells in a living mouse. These hardened cells, called fibroblasts, develop as a result of a heart attack (Myocardial infarction (MI) or acute myocardial infarction (AMI)), and impede the organ’s ability to pump blood.
