A University of Pittsburgh bioengineer uses experimental and computational approaches to study the neural mechanisms of eye movements directed to stationary and moving objects. The team records activity in neurons of the superior colliculus to understand how the brain processes visual information during saccadic eye movements.
Recent advances have shed light on neural circuits and mechanisms driving social behaviors, revealing a complex interplay of brain areas involved in cooperation and aggression. These findings suggest that shared neuronal activity between social partners plays a key role in cooperative behavior and learning.
A three-year AHA grant funds a multi-center study exploring the neural mechanism behind delirium and spatial neglect after right-hemisphere stroke. The research aims to develop novel attentional-behavioral therapies and diagnostic tools to reduce hospital morbidity and loss of independence.
Scientists at NERF have discovered a novel method to measure respiration dynamics, revealing that mice compare the strength of smells obtained through both nostrils for odor source localization. This process involves information transfer between brain hemispheres and has valuable implications for Alzheimer's research.
Researchers monitored neural activity of mated female fruit flies during yeast deprivation, identifying dopamine neurons that regulate protein appetite. Activation/inhibition of these neurons affects yeast preference and consumption, with increased activity linked to advancing hunger.
