brain neural circuits using magnetism.
Nano-MIND
Technology: Overview and Highlights
Overview
- Nano-MIND (Magnetogenetic Interface
for NeuroDynamics): New technology for exploring
and influencing brain functions like cognition, emotion, and motivation.
- Functionality:
Enables wireless, remote, and precise modulation of deep brain neural
circuits using magnetic fields and magnetized nanoparticles. An
improvement over traditional brain manipulation techniques.
Research
Highlights
- Demonstration on Mice:
- Maternal Behavior Induction:
Activated inhibitory GABA receptors in the medial preoptic area (MPOA),
increasing nurturing behaviors in non-maternal female mice.
- Regulation of Feeding Behaviors:
Targeted motivation circuits in the lateral hypothalamus. Activating
inhibitory neurons led to a 100% increase in feeding behaviors;
activating excitatory neurons resulted in over a 50% reduction in feeding
behaviors.
Significance
- Advancement in Neuroscience:
Marks a major advancement, potentially revolutionizing understanding of
brain functions and disorders.
- Applications:
Promising for developing advanced brain-computer interfaces (BCIs) and
therapeutic interventions for neurological disorders.
