Amplitude- and duration-sensitivity of single-on and double-on neurons to CF-FM stimuli in inferior colliculus of Pratt's roundleaf bat (Hipposideros pratti).

During hunting, the duration and amplitude of bat's echolocation sounds co-vary. Our previous studies showed the inferior collicular neurons of constant frequency-frequency modulation (CF-FM) bat discharged as single-on (SO) or double-on (DO) responders when stimulated with behavior related CF-FM sounds. However, how the co-varied sound duration and amplitude modulate the response properties of SO and DO neurons were understudied.

Latency modulation of collicular neurons induced by electric stimulation of the auditory cortex in Hipposideros pratti: In vivo intracellular recording.

In the auditory pathway, the inferior colliculus (IC) receives and integrates excitatory and inhibitory inputs from the lower auditory nuclei, contralateral IC, and auditory cortex (AC), and then uploads these inputs to the thalamus and cortex. Meanwhile, the AC modulates the sound signal processing of IC neurons, including their latency (i.e.

Association of the C47T polymorphism in superoxide dismutase gene 2 with noise-induced hearing loss: a meta-analysis.

Introduction: Currently, there is limited information about the relationship between manganese superoxide dismutase (sod2) c47t polymorphism and susceptibility to noise-induced hearing loss (NIHL).

Objective: The aim of this meta-analysis was to clarify the association between SOD2 C47T polymorphism and NIHL.

Methods: A search in PubMed and Web of Science was performed to collect data.

Research of the ATPase's rotation catalysis stochastic transition dynamics.

In this paper, based on the structure of the ATPase and the master equation, we put forward a stochastic hopping model which describes the rotary four-state motor's dynamics action. Finally, we obtained the relationship of the angle velocity omega, diffusion coefficient and the ATP's concentration, and got a result which accords with the rotary motor's biological mechanism.
