Strokes may increase desire for alcohol: Study

According to the study, stroke kills neurons in a part of the brain called the dorsal lateral striatum, and they stop inhibiting certain neurons in the mid-brain.

Glial – Brain cells that play vital role in controlling appetite identified!

Neuroscientists at MIT found that activating these brain cells stimulates overeating, and that when the cells are suppressed, appetite is also suppressed.

How brain zapping could decrease psychiatric symptoms

Electrifying brain circuits could treat neurological and psychiatric symptoms not because it causes neurons to fire but it creates an environment that makes it more or less likely for neurons to fire, researchers, including one of Indian-origin, have found.

Neuronal switch that turns off compulsive drinking urge

Researchers have found that inactivating a network of alcohol-linked neurons can switch off the urge for compulsive drinking.

What makes some people binge drink while others stay sober

Alcohol can reduce firing of neurons or brain circuits, which is why it reduces anxiety and social inhibitions, and those who are less sensitive to motor-impairing effects of alcohol are likely to drink much, the researchers said.

Sleep deprivation may lead to memory loss

It has been proposed earlier that changes in the connectivity between synapses - structures that allow neurons to pass signals to each other - can affect memory.

Maple syrup, the new brain food

A team of researchers has tagged maple syrup as a promising option in protecting brain neurons and nurturing young minds.

Not just pancreas, brain too regulates glucose metabolism

It can be applied to any circuit, including dispersed cells like those involved in the immune system.

Human skin cells hold promise to treat glaucoma

 Using stem cells derived from human skin cells, US researchers have revealed that these can be turned into retinal ganglion cells (RGCs) -- the neurons that conduct visual information from the eye to the brain -- to prevent or cure glaucoma.

Our `noisy` brain won't let practice make perfect

Our `noisy` brain won't let practice make perfect

A team of neuroscientists has discovered that "noise" in our brain causes us to make mistakes, suggesting that practice will never make perfect.

New method to 'weld' neurons using lasers

New method to 'weld' neurons using lasers

Femtosecond laser pulses - each ultrashort pulse occurring every 10-15 seconds - were delivered to the meeting point of the two cells.

Gut neurons help our immune system control inflammation

Different populations of macrophages are among the many types of immune cells present in intestinal tissue. 

Information flows in brain like well-defined travel routes

 Just as most of the world's air travel passes through a few major hubs, the majority of information in the brain flows through similarly well-travelled routes, a team led by an Indian-origin researcher from Indiana University has found.

Scientists identify 'fear switch' neurons in mice

Chinese scientists have discovered two types of neurons that can arouse or suppress innate fear induced by odour, a development that could benefit therapy for fear-related disorders.

Facebook ready to share artificial intelligence technology

Facebook ready to share artificial intelligence technology

Facebook is releasing for free the designs of a new computer server - twice as fast as those used by Facebook earlier, it designed to put more power behind artificial-intelligence software, MIT Technology review reported.

Did you hear it? Our vision and hearing is not very reliable

Our vision and hearing are not as reliable as we might think, the study by life scientists at University of California-Los Angeles (UCLA) said.

Daily exercise boosts brain power

Learning, memory, and brain repair depend on the ability of our neurons to change with experience says a new study.

High-fat diet also bad for brain

New YorkA high-fat diet also appears to prompt normally bustling immune cells in our brain to become sedentary and start consuming the connections between our neurons, a new study has found.

Umbilical cells help eye's neurons connect

 Cells isolated from human umbilical cord tissue produce molecules that help retinal neurons from the eyes of rats grow, connect and survive, a new study reveals.

How brain can enhance neuron connections

When the brain forms memories or learns a new task, it encodes the new information by tuning connections between neurons. Now, neuroscientists have discovered a novel mechanism that contributes to the strengthening of these connections, called synapses.
