Exploring How Attention-Switching Brain Networks Vary in Autism
Autism spectrum disorder (ASD) is associated with an increased focus on one’s internal experiences along with a reduction in responsiveness to external social surroundings. Now, a new study investigates the dynamics of brain connectivity between brain networks associated with internal experiences, external attention, and switching between internal versus external states.

Inside the Magnetosensitive Brains of Migratory Birds
How migratory animals find their way to the wintering grounds, thousands of kilometers apart from their breeding ground, is a fascinating riddle of nature. Now, neuroscientists have conducted a study to understand how birds know which direction to follow during long-distance flight.

How Does the Brain Keep Track of Movement in the Environment?
A new UCLA study has found that hippocampal neurons in rats accurately map the position of a moving object even while the rat is stationary. The results challenge the idea that the hippocampus, a region of the brain involved in learning and memory, only encodes a map of space based on movement.

Optogenetic Advance Sheds Light on Neural Activity
In the field of optogenetics, scientists investigate the activity of neurons in the brain using light. A team has developed a new method to simultaneously conduct laminar recordings, multifiber stimulations, 3D optogenetic stimulation, connectivity inference, and behavioral quantification on brains.

Impaired Cell Cleanup Could Drive Parkinson's Disease
Parkinson’s disease may be driven in part by cell stress-related biochemical events that disrupt a key cellular cleanup system, leading to the spread of harmful protein aggregates in the brain, according to a new study from scientists at Scripps Research.
