Link between Alzheimer’s disease and gut microbiota is confirmed

In recent years, the scientific community has suspected that the gut microbiota plays a role in the development of the disease. A team now confirms the correlation, in humans, between an imbalance in the gut microbiota and the development of amyloid pl…

Re-mapping taste in the brain

A new study found that the map of neural responses mediating taste perception does not involve, as previously believed, specialized groups of neurons in the brain, but rather overlapping and spatially distributed populations.

Astrocytes identified as master ‘conductors’ of the brain

A team of scientists has found that glial astrocytes are involved in regulating inhibitory synapses by binding to neurons through an adhesion molecule called NrCAM.

Repeated small blasts put military, law enforcement at risk for brain injury

Military and law-enforcement personnel repeatedly exposed to low-level blasts have significant brain changes – including an increased level of brain injury and inflammation — compared with a control group, a new study has found.

What happens in the sensory cortex when learning and recognizing patterns

Scientists are challenging the common understanding of how mammalian brains work.

Individualized brain stimulation therapy improves language performance in stroke survivors

Individualized brain stimulation therapy improves language performance in stroke survivors.

Framework to study brain connectivity in living organisms

A new study lays out a large medical analytics framework that can be used in neuroscience and neurology to study brain connectivity in living organisms.

Protein in blood may predict prognosis, recovery from stroke

Researchers have found that a biomarker in the blood may determine the extent of brain injury from different types of strokes and predict prognosis in these patients.

Compounds block stress-enhanced nicotine intake in rats

Researchers have discovered that compounds that activate GABA receptors in the brain can keep rats from self-administering increased levels of nicotine during stressful conditions in an animal model for relapse.

Detecting Alzheimer’s disease before symptoms arise

Both of Andrew Kiselica’s grandfathers developed dementia when he was in graduate school.
