Scientific Focus
· Physiology and biomechanics of auditory organs in mammals and insects.
· Focus: role of auditory motor proteins in generation of high sensitivity and fine frequency resolution of hearing
· Neuronal feedback and neuromodulation in auditory midbrain, thalamus and cortex
· Developmental plasticity of the auditory cortex. Focus: developmental emergence of echo-delay sensitive neurons and cortical chronotopicity in echolocating bats
· Role of attention in processing of auditory objects in rodents and human.
· Vibration sensors in spiders.
Methods
In vivo and in vitro electrophysiology, multiple electrode recordings. neuropharmacolocical methods, bioacoustic methods, laser-interferometry, measurement of otoacoustic emissions, human psychophysics, neuroanatomical and immunohistochemical methods
Animal models: rodents, bats, insects, spiders, humans
