Exploring How Neurons Talk Each Other

 SYNAPTIC COMMUNICATION LABORATORY

Our research aims to understand the concepts and mechanisms which underlie the complexities of the Brain. We use state-of-the-art technologies to explore how neurons connect and communicate with each other, how this connection

and communication are altered in neural diseases.

NEURAL COMMUNICATION AND ITS REGULATION AT SYNAPSES

.

 

We are interested in studying the Neuron and Synapses

which shape and guide the processes of the Brain.

Our long-term goal is to understand the underlying mechanism

of How neurons communicate with each other through Synapses.

 

Our major questions in research

  • How do neurons are connected in networks?

  • How do they communicate with each other once connected? 

  • How do neural diseases alter this basic functionality?

HIGH FIDELITY LIVE IMAGING

.

To monitor  synaptic physiology with high accuracy, 
We utilize a custom-built laser illuminating imaging system.
It leads us to observe various synaptic events from a single synaptic vesicle at the millisecond scale.
