Ordinarily, if you want to see what's going on in a bat's brain, you have to hold the animal immobile and wire it up – not the best setup for studying how it reacts while moving in the real world. Now, however, scientists have devised a method of recording the brain activity of free-flying bats.

University of Adelaide researchers have created a fiber optic probe that can reach deep into the brain to capture images and measure temperature. It’s been developed to learn more about hyperthermia to do with drug use, and may lead to new understanding of drug toxicology.

One of the clearest Alzheimer's risk factors is the gene apoE4. New research has peered closer at the protein encoded by this gene and uncovered how it affects the brain, how it increases the risks of Alzheimer’s and most importantly, how the damage can be reversed.

Researchers at Caltech have induced a range of sensations in the arm of a paralyzed man. Electrodes implanted in the brain stimulated the neurons to produce different feelings. The research could eventually lead to prosthetic limbs that allow users to feel realistic sensations through them.

A new study has revealed a stark connection between sleep deprivation and increased deposits of amyloid-beta in the human brain. This is the first study to clearly measure the increase in amyloid-beta in specific areas of the human brain after just one night's disturbed sleep.

A DARPA-funded study has raised the possibility of memory-enhancing brain prostheses. Patients who already had brain implants as part of epilepsy treatment and essentially had their memory played back to them experienced marked improvements to both short- and long-term memory.

A newly published study suggests adult human brains can produce as many new brain cells as younger brains. The research comes only a month after a controversial study claimed the human brain most likely does not produce new neurons beyond childhood.

If science is going to reduce a person to a 3-D map of physical structures, at least we can take solace in the fact that it's an incredibly complex map. Let's take a quick look at the emerging science of connectomics, the dense mapping of brain neurons, and how it's leading to better cryonics.

Researchers from Washington University have tested a new weapon in the fight against Alzheimer’s. In mice, the team has demonstrated an antibody that can clear away the disease’s build-up of proteins in the brain, which may lead to an early-stage treatment to prevent symptoms from occurring.

A study has found that a dose of human stem cells administered to rats bred to be high alcohol drinkers significantly reduced their voluntary alcohol intake. The research bolsters the growing hypothesis that stem cell treatments may be effective therapies to battle a variety of addiction disorders.
