One of neuroscientists insists that brain scans can read people’s mind, soon. In order to realize his thoughts, the neuroscientist uses EEG and fMRI data. Even though two methods still have limitations, scientists can reconstruct faces that subjects are viewing during the fMRI scan. Each scientist has their own algorithms to analyze brain data, but their fundamental goals is understanding how the brain does and what it does. A current issue of mind reading brings up important ethical and public policy questions about privacy.

Though many neurons have different shapes and sizes, they have common characteristic which neuron should have in general. But newly discovered cells have different and unknown process compared to basic neurons. In these neurons, the axon does not emerge from the cell body, but arises from a lower dendrite instead. The cells were discovered in the mouse brain, especially in the hippocampus. And human have the same general brain structure and types of hippocampus cells as mice.

A Chinese woman has been turned out that she doesn’t have large part of her brain. Nobody have known that even she is 24. She have problem on her cerebellum, which is called small brain that control voluntary movements and balance as well as learn specific motor actions and speak. But She is only mild problem speech and has moderate motor deficiency. This rare case occurs new interesting issue for many researchers.

People tend to think of our memories depend on his/her past. But the truth is, many studies show that our brains constantly edit our memories to rearrange events and change dialogue. Researchers has started researching by using engineered mice to control neural activity in the mice’s brain. Researchers give two stimulus, fear and happiness with electronic shock and interacting a female mouse. And researchers used a special blue light to control memories later. And on next experiment two group mice were experimented on opposite way. After this experiment mice had become terrified of their romantic playmates. This experiment could lead how unpleasant memories are formed in the first place and it would be helpful to clinical tools.

Scientists have developed the new mathematical technology for mapping large connections within the white matter tissue of living human brains. Differently from previous research, the new technology gives a mathematical analysis and open-source software to decide which of the two estimates is better.

Researchers have found the effect of listening to the favorite song with the functional magnetic resonance imaging (fMRI). Listening to the song, especially favorite song, activates that the adjacent region of hippocampus, which is involved in memory and emotion. This scientific result could support that the why the emotion or mental states were experienced differently by people listening to the different genre of music.

People usually know that transcranial magnetic stimulation influence only the superficial brain area. But the researchers have found that this kind of superficial stimulation can also affect the inner brain such as hippocampus which is involved in memory. Stimulation by using the repeated TMS alter the network connectivity with the center of hippocampus. If you are interested in this article, please check out the following link.

Researchers have developed the new technique being able to work as like fMRI. This device is called diffuse optical tomography. This device generates some tiny red lights to a subject’s scalp. Using this technique, the researchers can recover the fMRI-like image which enables to measure changes of blood flows in the human brain.

Researchers tried to prove that the hypothesis about relation between parietal reach region and the parietal eye field. With EEG, the processing of arm movements is figured out after receiving visual signal from our eyes.
