Researcher Profile & Settings


    Overview of research:
    My current research focuses on the abnormal sensation regulated through primary sensory afferents in the skin and the cornea as well as its synaptic regulation in CNS. I am also interested in cholinergic and histaminergic receptors regulating synaptic transmission in the hippocampus related to learning and memory.
