我们正在研究听觉背后的神经行为机制
英文摘要
We are investigating the neurobehavioral mechanisms that underlie auditory
function and communication in crickets because these insects can serve as
a model systems for understanding audition in higher animals. We are
studying how crickets discriminate among potential mates and rivals, and
how they detect and avoid predators, on the basis of acoustic signals. The
simplicity of a cricket's auditory behavior and neural pathways permits a
cellular analysis of how auditory information is processed and translated
into adaptive behavioral acts. The well-known acoustic startle response
(ASR) of mammals has numerous parallels in the ultrasound ASR of flying
crickets. Moreover, the AsR in crickets can serve as a model system to
investigate mechanisms of auditory processing that are ordinarily studied
in mammalian audition, such as the precedence effect, habituation,
prepulse inhibition, sensitization, and categorical perception. In the
cricket, the neural basis underlying this processing is subserved by much
simpler neural systems.
Behavioral plasticity occurs in audition and likely involves
neuromodulatory mechanisms. The simplicity of the cricket's auditory
system, and our knowledge of the cellular relationships in the neural
network underlying audition, provides an accessible experimental system
for the investigation of neuromodulation of audition at the cellular
level. The auditory behavior of crickets can be modified by manipulation
of stimulus conditions; the extent to which biogenic amines are involved
in modulating behavioral plasticity will be investigated.
Hearing has evolved many times in insects and has produced a wealth of
novel auditory mechanisms for both the detection and directionality of a
sound source. Tympanal hearing has recently been found in an acoustic
parasitoid fly. The structure and function of its hearing organ challenges
our understanding of how an ear extracts directional information from a
sound source. The opportunity to learn how other species solve such a
primary problem is a fundamental benefit of making comparative studies of
hearing, and these may lead to insights that touch basic issues in
hearing.
