MIT neuroscientists offered evidence that the inferior temporal (IT) cortex could distinguish objects. They used the data from both humans and primates, and found activation in the neurons of IT cortex, when subject recognizing some objects. Also they compared IT area with V4 area, and found that the neurons on each area activates in some objects but not others. Therefore the researcher said we could predict the flow of recognizing image, from the retina through V1, V2, V4 also in IT.

Once, we think that attention deficit hyperactivity disorder (A.D.H.D.) mainly shown from children and young adult. However, this write shows that we could find A.D.H.D. from elder people. Also, when elder has ADHD, the disease could confused with Alzheimer’s disease, which regarding old age.

Researchers from the Defense Advanced Research Projects Agency (DARPA) studied regarding a prosthetic hands. They implanted an electrode array into both motor cortex and sensory cortex. The brain region of sensory cortex recognizes tactile sensations. Those connected wires from motor cortex control the hand. The researchers also show it might be able to communicate sense of touch to the user.

We could often hear that exercising is good for physical health, and some intellectual capacity. The study shows the correlation between physically and mentally in children. Researchers used MRI to scan the brain. The MRI results from the child who had an ability in running on the treadmill for a long period of time showed less section of the gray matter in the front area.

There’s been an argument on how to categorize the gender of human being and recent neuroscience research suggests that
gender identity may exist on a spectrum and that gender dysphoria fits well within the range of human biological variation.

Team from Washington University School of Medicine and the University of Illinois was able to plant a device to several mice with a brain damage. They were able to control them with a remote control of the device.

The project, which coordinated by the Physikalisch-Technische Bundesanstalt (PTB) and which is one part of the project European Metrology Research Programme (EMRP), researched about whether people are affected by inaudible sound or not. Using magnetoencephalography (MEG) and functional magnetic resonance imaging (fMRI), the researchers could find that some area of the brain activates when infra/ultrasound is heard (above image). People can think that they couldn’t hear infra/ultrasound. However from the result of the research, we could find that those inaudible sound can affect people.

Electrophysiological recordings in the medial temporal lobe could identify the changes of the memory formulation in the corresponding brain regions. For examples, “Clint Eastwood” neurons/cell in this regions are also firing for the same person with different backgrounds (which is a new memory formation).

The researchers at the Stanford University School of Medicine found that between remote brain regions, there is genetic underpinnings. It shows that cognitive operation isn’t occur in individual brain region. Using functional magnetic resonance imaging (fMRI), they narrowed their focus into four functional networks. After that they looked at gene-expression profiles. Therefore from the gene activity, the researchers could find that the network-connectivity strength is shown in genetic-variant profiles of 136 genes.

The researchers from Carnegie Mellon University, were deduced the human thinking process using simple learning tasks. They used functional magnetic resonance imaging(fMRI) to find some activation in the brain. For the participants, the researchers taught them eight different animals. The participants learned about the diet and habits of the animals. Using fMRI, the researcher found brain region which regarding to ‘habitat’ and ‘diet’ respectively. ‘Habit’ regions shows the storing part of new information about where the animals lived, and ‘diet’ regions shows storing part of newly learned knowledge about animals. This research could apply to objects except abstract thoughts. Therefore it could be a help to figure out the systematic learning processes of human brain.
