Cockroach antennae
Cockroach antennae have been extensively used for studying the multifunctional sensory appendage that generates the olfactory, gustatory, tactile, thermal, and humidity senses. Of the variety of senses, the tactile sense is thought to play a key role for perceiving physical objects. Because most cockroach species are nocturnal, the tactile sense of the antenna would be essential to determine th...
متن کاملOne antenna, two antennae, big antennae, small: total antennae length, not bilateral symmetry, predicts odor-tracking performance in the American cockroach Periplaneta americana.
Determining the location of a particular stimulus is often crucial to an animal's survival. One way to determine the local distribution of an odor is to make simultaneous comparisons across multiple sensors. If the sensors detect differences in the distribution of an odor in space, the animal can then steer toward the source. American cockroaches, Periplaneta americana, have 4 cm long antennae ...
متن کاملCircadian rhythm in olfactory response in the antennae controlled by the optic lobe in the cockroach.
The olfactory response in antennae of the cockroach, Leucophaea maderae, was investigated by measuring electroantennograms (EAGs) in restrained animals. The amplitude of the EAG response to pulses of ethyl acetate, octanol, or fenchone, exhibited a robust, light entrained, circadian rhythm that persisted at least 14 days in constant darkness. Dilution-response curves measured at the peak and tr...
متن کاملAural Antennae
Aural Antennae are portable devices which translate sound impulses into vibrotactile stimulus. By swapping audio sensation for haptic sensation we illustrate one variety of artificial synesthesia. The compact devices can be worn to act as electronic travel aids for the hearing-impaired or used for augmented reality applications. Using a simple model of the audio scene’s background noise, the de...
متن کاملFractal Antennae and Coherence
Fractal antennae have very special properties: (1) They are broad band antennae, i.e. they radiate, and detect, very eeciently for a wide range of frequencies. The frequency range is speciied by the smallest and largest size present in the antenna. The radiation, and hence the detection, eeciency depends slowly on frequency between these two limits. (2) They can display considerable gain over n...
