Tuning the chemosensory window

Adaptive Window-Tuning Algorithm for Efficient Bandwidth Allocation on EPON

Ethernet passive optical network (EPON) has been considered to solve the last mile bottleneck problem. In an effort to accommodate the explosive bandwidth demands from subscribers, the optical line terminal (OLT) efficiently divides and allocates time slots for data upstream to all optical network units (ONUs) in EPON. This technology is expected to be a core in the future fiber-to-the-home/-of...

Critical period window for spectral tuning defined in the primary auditory cortex (A1) in the rat.

Experience-dependent plasticity during development results in the emergence of highly adapted representations of the external world in the adult brain. Previous studies have convincingly shown that the primary auditory cortex (A1) of the rat possesses a postnatal period of sensory input-driven plasticity but its precise timing (onset, duration, end) has not been defined. In the present study, w...

The Flexibility of Chemosensory Preferences

Chemosensory tuning to a host recognition cue in the facultative specialist larvae of the moth Manduca sexta.

Larvae of Manduca sexta are facultative specialists on plants in the family Solanaceae. Larvae reared on solanaceous foliage develop a strong preference for their host; otherwise, they remain polyphagous. The host-specific recognition cue in potato foliage for Manduca larvae is the steroidal glycoside, indioside D. Two pairs of galeal taste sensilla, the lateral and medial sensilla styloconica,...

Chemosensory Perception in the Gut.

The ability of the gut mucosa to sense the chemical composition of chyme is important for gastrointestinal functions. The demonstration of gustducin and transducin, two alpha-subunits of GTP-binding proteins involved in gustatory signal transduction, in gastrointestinal epithelial cells provides first clues to the molecular basis of enteric chemosensitivity. Nitric oxide may play a role as a se...
