Artificial synapse that works with living cells created

Researchers have created a device that can integrate and interact with neuron-like cells. This could be an early step toward an artificial synapse for use in brain-computer interfaces.

Exposure to air pollution impairs cellular energy metabolism

Exposure to air particulate matter impairs the metabolism of olfactory mucosal cells, according to a recent study. The results can contribute to a better understanding of how air pollutants may harm brain health, as the olfactory mucosa can act as a ke…

Discovering how the brain works through computation

Researchers propose a new computational system to expand the understanding of the brain at an intermediate level, between neurons and cognitive phenomena such as language. They have developed a brain architecture based on neuronal assemblies, and they …

COVID-19 threatens the entire nervous system

A new review of neurological symptoms of COVID-19 patients in current scientific literature reveals the disease poses a global threat to the entire nervous system. About half of hospitalized patients have neurological manifestations of COVID-19, which …

Brain cells can harbor and spread HIV virus to the body

Researchers have found that astrocytes, a type of brain cell can harbor HIV and then spread the virus to immune cells that traffic out of the brain and into other organs. HIV moved from the brain via this route even when the virus was suppressed by com…

Clues to aging come to light in vivid snapshots of brain cell links

Striking images of some five billion brain cell connections have been created by scientists, mapping a lifetime’s changes across the brain in minute detail.

Adult stem cell study shows fish oil may help with depression

A new study shows that patient-derived adult stem cells can be used to model major depressive disorder and test how a patient may respond to medication and that fish oil, when tested in the model, created an antidepressant response.

Neuroscientists discover neural circuits that control hibernation-like behaviors in mice

Neuroscientists have discovered a population of neurons in the hypothalamus that controls hibernation-like behavior, or torpor, in mice, revealing for the first time the neural circuits that regulate this state. By better understanding these processes …

The brain uses minimum effort to look for key information in text

The human brain avoids taking unnecessary effort. When a person is reading, she strives to gain as much information as possible by dedicating as little of her cognitive capacity as possible to the processing.

Baboon model could aide in Alzheimer’s disease interventions

Scientists recently published findings indicating the baboon could prove to be a relevant model to test therapeutics and interventions for neurodegenerative diseases, such as early stage Alzheimer’s and related dementias.
