Cocaine makes brain cells cannibalize themselves, says study on mice

Cocaine makes brain cells cannibalize themselves, says study on mice

Researchers have contributed significant new evidence to support the idea that high doses of cocaine kill brain cells by triggering overactive autophagy (normal physiological process in the body that deals with destruction of cells), while working with mice.

Brain 'switch' to turn off nicotine cravings identified

Scientists have identified a fat molecule in brain cells that may act as a 'switch' to increase or decrease the motivation to consume nicotine, a finding that could lead to new therapies to help smokers kick the butt.

Three-decade old pesticide in milk linked with Parkinson's

 A pesticide used prior to the early 1980s and found in milk at that time may be associated with signs of Parkinson's disease in the brain, researchers reveal.

How jogging helps you stay sharp- Read inside

Exercise can enhance the development of new brain cells that play an important role in learning and memory of adults, new research has found.

Artificial skin to give people with prosthetics sense of touch

Researchers have developed a new artificial skin that can 'feel' similar to the way a fingertip senses pressure, and may help people perceive sensation in their prosthetic limbs.

Jet lag-like sleep disruptions spur Alzheimer's memory loss

Glutathione deficiencies produce redox changes in brain cells. Redox reactions involve the transfer of electrons, which leads to alterations in the oxidation state of atoms and may affect brain metabolism and inflammation.

Our memories reside in specific brain cells: MIT researchers

Our memories reside in specific brain cells: MIT researchers

The researchers used optogenetics to show that memories really do reside in very specific brain cells, and that simply activating a tiny fraction of brain cells can recall an entire memory.

Decoding brain cells' moods may manage alcoholism: Study

These brain cells called Purkinje cells, located in the cerebellum at the base of the brain, are essential for our body's balance.

Indian-American scientist uses sound waves to control brain cells

Indian-American scientist uses sound waves to control brain cells

In a first, an Indian American researcher from Salk Institute for Biological Studies in California has developed a new way to selectively activate brain, heart, muscle and other cells using ultrasonic sound waves.

Diabetes may be linked to brain tangles, separate from Alzheimer's disease

A new study has suggested that Diabetes and the buildup of tangles or tau in the brain may be linked independently of Alzheimer's disease.

Common antidepressant may help stroke victims recover

 A commonly prescribed antidepressant may help stroke survivors improve movement and coordination even when rehabilitation after the stroke incidents gets a little delayed, new research has found.

3D-printed 'bench-top' brain a reality soon

3D-printed 'bench-top' brain a reality soon

In a step closer to creating a full-fledged “bench-top” brain, Australian researchers have developed a 3D-printed layered structure incorporating neural cells that mimic the structure of brain tissue.

Even when brain shrinks with age, cells' density remains constant

 A new study has revealed that cell density remains constant even though the brain shrinks with age.

Light energy to help retrieve lost memories in amnesiacs

Memories that have been lost as a result of amnesia can be retrieved by activating brain cells with light, a study suggested.

Pesticides alter bees' brains, affect reproductive ability

Pesticides alter bees' brains, affect reproductive ability

New research suggests that a particular class of pesticides called "neonicotinoids" do not kill bees but impair their brain function to disturb learning, blunt food gathering skills and harm reproduction.

Study links gene to thinking skills

A group of researchers have found that genes might be linked to a person's quick thinking skills in his or her middle and later life, a study by the University of Edinburgh says.

How 'love hormone' leads to maternal instincts

Scientists have unraveled how the "love hormone" oxytocin acts on brain cells to make females understand and tend to their offspring's needs.

Vitamin E deficiency can damage brain

Eating diets rich in vitamin E can help you stay sharp as researchers have found that deficiency of this vitamin may cause damage to brain cells.

Novel treatment for dementia shows promise

In a ray of hope for people suffering from dementia, researchers -- led by one of Indian origin -- have found that stimulating the brain though minute amounts of electricity enhances the growth of new brain cells and improves short and long-term memory.

Brain 'switch' that controls your appetite discovered

Researchers have discovered tiny genetic triggers in brain cells that can have a big influence on how the body regulates appetite and weight.
